Fredericksburg’s STEM Academy/Rocket Program-Spring Term Update #2 (February 21-March 31)

April 1st is tomorrow, so time is becoming a factor for the Fredericksburg STEM Academy as launch dates approach for the junior and senior groups. There are no fools here though, just several groups of future engineers working hard to meet their timelines. With March behind them there is only a little over 6 weeks left for the junior group until Rockets 2017 and their May 18th test date. The seniors have approximately 60 days as Redbird 18 is scheduled for completion two weeks before school ends to allow for preliminary systems tests.

More on these groups and their current status reports will be later in the article.

Sophomores are currently taking mid-term exams. This is due to the new schedule for classes this year which puts a full year’s curriculum into one standard semester. They have been busy using AutoCAD to create multi view drawings of objects. Dimensioning and tolerancing of these drawings will be learned next, followed by isometric drawings and 3D modeling. The students have been printing models of their multiview drawings using the newly installed 3D printer. All 3 3D printers available now are working well.

The student aide, Colby Marthaler has also been using the 3D printers to print all the parts necessary to create a model of the Falcon 9 Rocket SpaceX uses to transport satellites and the Dragon spacecraft into orbit.

Juniors had CDR’s (Critical Design Reviews) due for their rockets by March 30. Unfortunately they are just getting to them. Students will have to be studious in order to meet their May 18th launch date due to being behind schedule at this time. The payload for this rocket is a rapid growth slime mold. They have designed the payload in order to create a controlled experiment in which they should be able to determine how flight impacts the mold’s growth, negatively or positively.

The design criteria for their rocket is a one pound payload and breaking the speed of sound therefore achieving a transonic state. Currently neither criteria has been met so the group has more work to do to accomplish their goals by their launch date.

Their mid-term which is a LabVIEW development project has come along well. They are creating a workable program which requires specific methods and functions in order to attain a goal of designing and fabricating a micro test stand for Estes motors. They will be connecting a (DAQ) Data Acquisition unit to a computer and registering it to that computer in order to read sensors, and programming a control and DAQ Virtual Instrument in LabView in order to run the test stand.

March began with more fuel grain tests at test stand. Two tests were completed in the first week alone, consisting of many hours of work to accomplish each. A temperature sensor indicated a high enough value in order to cause a programmed shut down on the first test that week. After investigation, it was found that a ‘electrical noise’ caused an anomaly which gave the sensor its reading, and that it was in fact not outside normal operating parameters. The actual test did not experience any temperature concerns.

The same fuel grain was able to be used again in a 20 second burn, which allowed students to achieve a cumulative 40 second burn on one fuel grain. The shut down was disabled for the second burn, allowing the data to still record the temperatures caused by the ‘electrical noise’, but not to stop the burn test and it was a full success without any further exceptions.

Mr. Matthes was very pleased with these burns and stated , “All data was processed and showed again the test stand was producing verifiable data similar to theoretical expectations.”

Students began another round of testing this week. Six new fuel grains will be tested accounting for three tests each of two different fuel types students have been working on. The hope is that they will cycle through smoothly due to the fuel grains being prepped prior to testing.

Here Hannah Boubel is working with graphite in order to make ablative, which is a sacrificial material in the pre and post combustion chamber so the burn does not penetrate the liner and steel test cell.

In this photo, Sterling Weatherford is preparing a fuel grain for installation in to the test cell.

Along with test stand work, the students have been hard at work on Rebird 18, their Goddard level rocket slated to launch at White Sands Missile Range on June 27th. Students have already contracted with Heartland Enterprises and SRM Manufacturing for fabrications and parts have been supplied to them.

At this point in the process students are learning true cause and effect, and just how it can affect their outcomes. The entire success of the vehicle from this point forward is contingent on the group not only working as a team as a whole, but also for each individual team to stay on top of their work and outcome. Many of the components are dependent on the progress of the others. Delays on one team’s element directly affects the next team creating delays down the line and strained time schedules. Individual testing is conducted on each piece as it is finished. Full up integration and testing of any systems that allow for ground based testing is scheduled for two weeks from the end of school when the rocket is due to be complete.

“They are well on their way to a successful vehicle. The seniors will not have the luxury of adopting senioritis as there is still significant and mutually dependent work to be accomplished,” Mr. Matthes reported. “These next 60 days will be a true test of their team work, peer loyalty and persistence. ”

As the end of the school year approaches, these students are becoming more and more adept in their learning and knowledge as young and capable engineers. Their end of year rockets will be a testament to that learning, time and ability.

According to Mr. Matthes, “Students are becoming ‘plagued’ with knowledge and experience: the more they know and become aware of, the more they have to take into consideration and the more challenging the process becomes. However, it also makes for conditions more aligned with success. Additionally, if we consider these students products of FHS and the FHS Engineering, then they should be welcomed by a market hungry for what they have to offer.”

The senior group is tentatively scheduled to launch their Goddard level rocket at White Sands Missile Range (WSMR) in New Mexico the week of June 26-30. The current schedule for that event is as follows:

Sunday, Jun 25th Travel Day

Monday, Jun 26th T-1 and Site Set up/Rocket Prep at WC-50

Tuesday, Jun 27th Launch Day One (Three Rockets – Fredericksburg, Union Grove, Alamo Heights)

Wednesday, Jun 28th Launch Day Two (Three Rockets – Anahuac, Booker T. #1, Booker T. #2)

Thursday, Jun 29th Contingency Day

Friday, Jun 30th Travel Day

There are also launches in Houston for schools in that area the weekend of May 12-14, 2017. New for this year the Hobbs, New Mexico group of schools will launch 1/1 rockets in Jal, New Mexico on April 27, 2017, this site will also be open to public viewing.

Second Term Update #1 (January 9-February 21)-Fredericksburg’s STEM Academy/Rocket Program

January is past and February is waning quickly, but the spring program is really building. There are big goals and events for each class group. This semester is where their learning hits the pad literally for the junior and senior groups as they build toward Rockets 2017 and their end of class projects. There are three class groups this semester as the sophomore class begins study and the freshman class is complete until they re-enter the program as sophomores in January of 2018.

The freshman have moved on due to the new accelerated block schedule, but at the end of the semester they all agreed that communication skills were what they felt they had developed the most. They found themselves to be much more comfortable and proficient when speaking in public. Their final projects, the orange juice production plants went well as reported by Mr. Matthes. The students were all very excited about the class and course study, but not about having to wait a whole year to return to the STEM Academy.

The sophomores are just beginning their 5th week of studies since they are new to the program for this year. Their studies to this point included learning to hand draw multi-view drawings, interpreting 3D objects, and learning engineering lettering which they have recently completed. With these skills accomplished, they will be moving on to the ACC Auto CAD course within the next week.

These students have been using two older 3D printers for these projects. The printers have a relatively small build space and so limit what the students can produce on them. The district has recently received a new larger 3D printer, the MakerBot Z18 which will be available later this month. This will be a benefit to these students as well as both upperclassmen groups as it will allow for much larger production pieces and will give them the ability to prototype designs.

While junior and senior classes will use this printer more often, the sophomores will be the first to learn how to use it. Even though their current course study will still be focused on smaller printing jobs, prototyping and future uses will necessitate knowing how to use the new printer.

Juniors began work on January 23, on their transonic rocket that they will launch in Willow City in May. They have begun the initial stages of the Design and Development processes. A timeline and a problem statement have been created, and they are about midway through the research process.

They have a Critical Design Review (CDR) due before spring break. Unfortunately they have not been able to narrow down the scope of their research as of yet. This keeps them spread out as a team, and means they have to make up ground in order to make the pre-spring break CDR deadline.

They are researching rapid growth organisms for a possible payload for the rocket, and hope to be able to study how flight affects their growth.

On Friday, February 17, the juniors along with sophomores, Gloria Burns and Eston Cooke joined the juniors as Brian Evans of Space Propulsion Group provided instruction on the basics of mathematical modeling. At the end of the presentation, juniors had the opportunity to present models they had developed and then also do trouble shooting on their profiles.

Sophomores Gloria Burns and Eston Cooke with Dr. Brian Evans.

The junior students were very receptive to Mr. Evans and his instruction, alleviating numerous roadblocks and enabling rapid progress in their modelling.

Here juniors, Harrison Spisak and Jacob Weinecke make their presentations their burn model to Dr. Evans.

“Dr. Evans was down to earth and made comprehension of something really difficult, easy.”-Corbin Smajstrla

“It was nice to have rocket science explained so it wasn’t rocket science.” -Evan Knapp

Juniors have been officially invited to begin learning and participation in fuel grain motor test burns, but currently seniors are the only ones conducting any test burns.

Corbin Smajstrla and Dr. Evans at the board.

The seniors conducted their first hot fire test on Friday, February 17, while Dr. Evans from the Space Propulsion Group was in attendance. They accomplished a 10 second burn of Low Density Polyethylene (LDPE).

A still photo from the burn test.

According to Mr. Matthes, ” The test was extremely successful with outstanding data acquisition that showed the motor preformed nominally, according to expected design parameters. This was very exciting to have such a good, clean burn, good data, and fitting expected performance.”

Heartland Enterprises and SRM Manufacturing created a newly designed injector plate. This allowed the class to keep their Friday deadline. In spite of the piece needing to be manufactured quickly for the project, these companies came through and the product was, “beautifully machined and performed with 10% of expectation regarding oxidizer mass flow rate,” stated Mr. Matthes.

On January 27, the Fredericsburg Middle School 7th grade GT(Gifted and Talented) group presented their payload for the Redbird #18 Rocket to the senior STEM class. It consisted of a group of sensors to measure UV Light, methane, acceleratometer, and barometric pressure.

The 7th grade GT class presentation.

New this school year, Mr. Matthes started requiring after school and extra curricular hour work on senior projects. When asked how this senior group was doing with this on their project, here is what he had to say about the group.

“There have been a solid group of students who have been putting time in during study halls and some others who have been able to commit extended numbers of hours outside of school time to keep things moving forward. These senior students have worked phenomenally. They bit off a lot to accomplish this year and are on target to meet all of their expectations. It is quite remarkable having the opportunity and privilege to work with them. A substitute recently commented that during my absence, walking into the classroom after the passing period between classes was like walking into a full-fledged workforce environment where students were all fully engaged, scheduling, designing, problem solving, and just plain working without any instruction to do so. I believe the skills these students have honed over the last 4 years through this program and all their other coursework has created a ‘product’ that any college, industry, and organization would wish to recruit.”

Keep up the great work, seniors, what an amazing and glowing endorsement.

If you follow this program and like to view the launches, Rockets 2017 will be held at the Stewart Ranch in Willow City, Texas on the weekend of May 18-21, 2017. This testing site is open to the public. Please watch the SystemsGo website and this blog for upcoming information on the event. The FHS junior group will be testing their rockets on Thursday, May 18, 2017. The senior group is tentatively scheduled to launch their Goddard level rocket at White Sands Missile Range (WSMR) in New Mexico the week of June 26-30. There are also launches in Houston for schools in that area the weekend of May 12-14, 2017. New for this year the Hobbs, New Mexico group of schools will launch 1/1 rockets in Jal, New Mexico on April 27, 2017, this site will also be open to public viewing.

The STEM Academy group was encouraged to attend the movie, “Hidden Figures” on Friday, February 10th at Fritztown Cinema. About 35 students from the program attended. Here is what a few of them had to say about the movie:

“The movie was about African-American women breaking social barriers in the engineering community at NASA. It should be your talent, skills, and work ethic that decide your position at your workplace, not your ethnicity or gender. I found it to be a fun/feel good movie that was well-directed and enjoyable to watch. I found myself caring about the characters and rooting for them throughout the movie which means the characterization was done well. My favorite part of the movie was the climax when they shot the marine into orbit. The entire movie was building up to this and it was worth the wait.”–John West

“I found “Hidden Figures” to be a very inspiring and thought-provoking film. The primary idea that I took away from the movie was to “look past the numbers.” During the film, NASA mathematicians had difficulty making complex calculations due to there being no existing method available to make them. The protagonist of the film “looked past the numbers” and was able to use her intuition to come up with calculations that fit the situation. In rocket science, numbers are nothing without a physical attribute to tie them to. My favorite part of the movie was when the machine that made quicker calculations than humans malfunctioned and the protagonist was brought in to confirm them. This invoked the idea that machines, although they may be faster, can never replace the need for an engineer.”–Jacob Weinecke

Wishes for the New Year

Once again, the old year passes away.
We greet a new year at the dawning of a new day.
May we each find a way,
To be kind in all we say.

May the New Year bring us hope,
And a new found strength with which to cope.
May we always find a strong hold no matter how steep the slope,
As well as the sense to know when to say, “Nope!”

May we always show love and kindness
To family and friends even in duress.
May we not be overloaded with stress,
And may goodness of character, we always possess.

May we always remember the power of a kind touch,
And how it can mean so much.
May we never hesitate to lend a hand or be a crutch
To those who for strength to us clutch.

May we remember the very young and the very old
And not forget their hands to hold.
May we have courage and be bold,
That what is right we may always uphold.

May we always show love,
In the manner shown to us from above,
Wrapped around us and others as a glove,
A sign to all who meet us, of His love.

May blessing abound in your new year,
Bringing you hope and good cheer.
May your way be clear
And your course easy to steer.
Have a Happy New Year!

Once Upon A Christmas Day

Once upon a Christmas Day,
On the floor asleep I lay.
Cuddled beneath the Christmas tree,
With a fire blazing in the stove next to me.

The lights were shining with colors bright,
Casting warm reflections in dawning light.
My eyes though mostly still asleep,
Still saw their beauty in the dreams of sleep.

Around the tree and my resting head,
Dozens of presents had been shed.
Bright colored wrapping covering each one,
Each tied with a bow when it was done.

Stockings were hung from cabinet knobs,
Filled with goodies by the gobs.
Pretty decorations sat here and there,
Santas, Snowmen, and Angels placed with care.

A miniature village covered the shelves,
Seemingly put there by Santa’s elves.
All of these show beauty and splendor,
And inspired joy on a morning yet tender.

Two things stood out most important of all,
Displayed on a table, not decking the hall.
The first was a Bible opened to Mark,
Telling the story the angels did hark!

The second was a crèche depicting the scene,
Of the Christ child’s birth in a manger mean.
Despite all the trappings, He is still the reason,
There would be no true Christmas, He is the season.

We enjoy all the lights and the glitter and bows,
But may each person who celebrates, truly know;
That it is only this way because God made it so,
It’s according to his plan that this Jesus we know.

There is no meaning in all at Christmas we share,
If Jesus Christ our Lord is not kept there.
There is no reason to have great joy,
If the Savior does not this Holiday employ.

Once upon a Christmas day,
Christ was born in just God’s way.
He came to save us from all sin,
So that the Devil should not win.

It’s all according to God’s plan,
That His true story the world should span.
So as I awake to Christmas bright,
I first celebrate the Christ, born Christmas night.

The Season is So Bright (Villanelle)

Oh the Season is so bright,
Filled with decorative, fancy fare;
Beautiful, colorful, twinkling lights.

To the eye what a delight,
With cards and food and gifts to bare;
Oh the Season is so bright.

Buildings adorned to the heights
With bows, and trees, and holiday ware;
Beautiful, colorful, twinkling lights.

What joy that fills our busy plight,
As love and stories and songs we share;
Oh the Season is so bright.

What a wondrous shining sight,
That as we pass, we stop and stare;
Beautiful, colorful, twinkling lights.

The excitement of Christmas night,
Reminding us to stop and care;
Oh the Season is so bright;
Beautiful, colorful, twinkling lights.

First Term Wrap Up (Nov. 18-Dec. 21)- Fredericksburg’s STEM/Rocket Program

December is nearly over and Winter break starts today, but before we send the Fredericksburg High School STEM Academy home for Christmas, we need to review what they have been working on these last four weeks, and try to wrap up the fall program. January starts the spring program loaded with really big goals and events that this past fall has been building toward. Each group’s learning will be evident in the success of this coming semester’s projects.

During the month of November the Freshman visited Toyota Manufacturing and Southwest Research Institute (SwRi).

The students were impressed with Toyota and how huge the plant itself is, as well as the difference in the type of automation used as compared to last month’s visit to Caterpillar. Toyota’s assembly line resemble Ford assembly lines. The components actually moved along on a line and each team had an assigned task as it moved by them. Caterpillar operated in stages where one team did several components before it moved to the next staging area.

Mr. Matthes remarked that ” The delivery logistics of parts to the assembly line was phenomenal!”

On December 13, the Freshman group visited Fischer and Wieser, Heartland Enterprises, and UT Aeromechanical Lab.

Fischer and Wieser and Heartland are Fredericksburg companies. They both demonstrated automation on a small-scale as compared to companies like Toyota and Caterpillar. Fischer and Wieser explained the importance of loyal employees and a family like environment.

Heartland is similar in framework and belief on how they treat their employees. Where as many companies prefer to hire very experienced candidates from other companies, Heartland prefers to hire inexperienced people and train them in their ways of operation. They find that by doing this they keep a certain working quality and alleviate the bad habits that experience can sometimes bring with it which can be adverse to the companies current operating practices and quality control initiatives.

Below are pictures from Heartland Enterprises:

Here, Alvin Culak, shows machine operations to students.

Students at UT Aeromechanical Lab and Flow Field Imaging Lab in Austin, were working on ablative testing for high velocity projectiles or vehicles, and a research lab studying hydrogen combustion and anomalies that may exist with it. These anomalies must be understood before hydrogen combustion can be considered for fuel. They are also studying wind tunnel testing designed to help discern the tendencies of shock for use in ramjet and hyper velocity propulsion systems.

Below, candidates took time with the students to explain and exhibit their work.

For more information on this: https://utexas.box.com/s/n1kk9ozocyp8ozloo9dm9ujx23q6vuwj

Dr. Noel Clemens is the Principle Investigator for all experiments in the lab, and the primary decision maker. Jeremy Jagodzinski is the lab facilitator. He helps to support the research in the lab and also set up the visit for the students. Phillip Varghese oversees the Center for Aeromechanics Research which often collaberates with this lab. Thank you to all of them for facilitating the tour.

Mr. Matthes stated that, “the students really loved the research facility.”

Aside from field trips to see first hand about automation and manufacturing, the freshman have been learning about production/automation engineering. They are currently in the process of designing an orange juice production plant. Their product goal for the plant is to take raw material and produce packaged juice in palletized product bundles ready for sale. Jenny Weiser will be coming in January to see their presentations and evaluate and provide constructive criticism.

Sophomores will be entering the program for the second term, starting Jan. 23. ACC’s Auto CAD course will be their main focus learning to utilized specific skills and design elements.

The juniors flew their Generation 3 rockets recently. This provided several learning points that will be useful on their projects next semester. Students realized that even cutting edge design doesn’t always transfer well into the manufacturing ability of the vehicle. Failures in these construction and design frailties, resulted in irregular flight patterns. These mishaps translated into two days of Post Mission Analysis insuring that lessons from this would not carry over to next semester’s larger rocket project.

Here the juniors are building their G3 rockets.

In January, the juniors will begin work on their one pound/one mile vehicles to be tested out at Willow City in May. This is considered a sounding rocket designed to break the speed of sound without breaking a ceiling of 13,000 feet while carrying a one pound payload.

Seniors have been very busy, and experienced both successes and set backs on their projects recently. Testing on fuels is expected to begin in January as they are nearly complete with updates on test stand.

After manufacturing pieces for their small motor test stand out of 2024 aluminum, they discovered that this metal type cannot be welded. This resulted in having to procure another high strength aerospace aluminum which is conducive to welding. Once they find this they will have to begin again the manufacturing of the fuel grain containment system.

“These were very important lessons learned for all, them and me,” stated Mr. Matthes.

Preliminary Design Reviews were conducted on their Goddard level rocket, last week. Due to the set backs on test stand, previously discussed, the group lost time they should have had to work on their rocket design and therefore have a bit of ground to make up there in order to have those completed by January’s end.

Happy Thanksgiving All

I had planned to post something that I had written in the past for Thanksgiving, only to discover I couldn’t find anything I had written in the past for Thanksgiving. How sad, I thought, such a wonderful holiday and I have never taken the time to write a word about it. Well, now I shall remedy that, even if at the moment I have no idea what I plan to say. So you will just have to bear with me a bit!

It is odd that I haven’t taken the time to write about this holiday since I know it is one of my favorites and I know many say the same. I think it stands out as such because it involves all the wonderful aspects of a holiday without so much commercial fuss. Yes, it does still have some, but not like Christmas, Easter, and Halloween.

It is designed as a holiday of thanks and sharing of all that we have, so we take the time to get together with family and friends and prepare and share food, fellowship, fun, parades, football, hunting, church, prayer and thanks. We share sheer joy at just being together. Our gifts for this particular holiday are our food, our joy, our love, and our companionship. We wrap them in smiles, hugs, tears and laughter.

We relax, visit, watch football, play games and eat all day long, and in our case late into the night. In fact sometimes it becomes a campfire party later in the evening.

The biggest stress is preparing food and cleaning at the house. Yes I said it that way on purpose because quite often all the cleaning never gets done (mostly dusting, the floors and bathrooms are clean-hey if you can’t handle that, write your name in the dust and then politely leave through the same door in which you came), and my family never seems to mind. What didn’t get done will get finished as the Christmas decorations go up next week. Besides, I live in a sand field and I can dust today and it will look like I never did by tonight, especially if the windows are open which they have been off and on lately. But I digress, that is not the point. The point is we get together for this holiday to give great thanks and to just plain eat and have fun.

The stressful stuff starts on Friday as we start shopping for that next biggest holiday of Christmas. But for Thanksgiving Day, wake up, watch the sun rise and go enjoy your family. I know that is what I am going to do. Actually most of them are coming to my house. I wish every last one of them was, but unfortunately some due to circumstances just cannot. I pray that where ever they are, they are safe and have a wonderful day anyway.

God bless and give thanks for all you have, and pray for those less fortunate than you that may not being having such a wonderful day. May God bless and keep them and fill their needs as well.

Happy Thanksgiving All may you have a wonderful and blessed day.

Fall Highlights (Oct. 1-Nov. 18)- Fredericksburg’s STEM/Rocket Program

It is mid November and time to review once more all that the Fredericksburg High School STEM Academy has been working on throughout the past seven weeks. Each group has new skills they are learning, goals they are working to achieve and events they are working towards.

During the month of October the Freshman visited Caterpillar Manufacturing, where Warren Houston, Caterpillar plant manager, acted as the groups’ host during their tour. They also toured Aqua Power Cutting, where owner BJ Millard showed them around and gave demonstrations. Mr. Millard’s two sons have both participated in the STEM Academy.

The following photo is from their visit to Caterpillar Manufacturing.

On Monday November 21, they will visit Toyota, Center for the Intrepid, and Southwest Research Institute (SwRi).

They have also been learning about Electrical Engineering. Keith Kunz a representative of Teledyne, formerly Real Time Systems, was on site Thursday, November 10 for subject presentations.

The juniors have been studying aerodynamic drag, resistance, and impulse momentum theory. They are completing work on the test stand burn models and the associated fuel grain burn simulations. After this they will be moving on to new heights, attempting to reach 1900 feet on C6-Estes motors in Generation 3 rockets. These rockets are designed using the same RockSim software used to design rockets they will launch at Willow City next year. This is a lesson in design and construction and each must match identically their design.

The whole senior group made a trip to NASA Johnson Space Center on Monday and Tuesday, November 7 and 8. Only two were unable to attend, one due to family complications and the other was attending State Marching Contest on Monday with the FHS Band but joined the group later.

On Monday they collectively made a Grant Presentation to NASA. Mr. Matthes reports that, “they did wonderfully.”

On Tuesday, Ian Kendrick, Sterling Weaterford, Nathan Bain and David Becker presented a flight readiness profile. “NASA was impressed with test-stand updates and the focus on analysis and improved data acquisition,” according to Mr. Matthes.

They also toured Johnson Space Center.

Students had time for fun while in Houston as well. On Monday, after dinner, students spent time at Kemah Boardwalk. Interestingly the “Crane Game” was the entertainment of the evening, pitting them against each other to see who could pluck the most stuffed animals. Reportedly, Ricky Robles was the winner.

Those not involved in Tuesday’s presentation went to Space Center Houston where a good time was had by all.

The STEM Academy would like to extend many thanks to Mr. Logan Minshew, FHS Counselor and CTE coordinator. He took the time to attend this field trip and drive the group.

In other senior news, even though there is still quite a bit more to be done on test-stand, they have made good strides and are progressing forward diligently. They are back at work with rocket design as well.

In a related note, Mr. Matthes reports that they held their first Engineering Advisory Committee meeting on Friday, November 11. Members present were Brian Evans (Space Propulsion Group), Jay Mallinckrodt (Heartland Enterprises), and Scott Netherland (SystemsGo). Mark Cornett, Allen Nance (Teledyne), Luke Morin (SRM Manufacturing), and Logan Minshew (FHS Career and Technology Coordinator) were unable to attend.

Happy Halloween-The Final Fare Cafe’

My arms were full of food which I balanced against the wall as I opened the cooler door and reached in groping for the light switch on the wall inside. As my hand finally made purchase of the switch, someone else’s hand clamped tightly over my wrist preventing me from turning the light on. Stunned I shrieked briefly, dropping my load, before standing there wide-eyed, and still, unable to move and unsure if I should. As far as I knew, I was alone, all of the other staff in the restaurant had gone home, so I had no idea who to expect. After a few seconds I finally gathered my wits, or perhaps lost them, and hollered, “Who’s in there? Let go of me and show yourself.”

There was no answer, but the hand suddenly released me and I yanked my arm back and slammed the cooler door. I knew there was a safety latch inside, and whoever was in there could still get out. Grabbing a rolling-pin off a rack near the door, I waited. Nothing happened, not even a sound. My hands shook, and my wrist still felt the imprint of icy fingers as I braved the door again. I grabbed the latch and yanked the door wide backing away quickly. No one came out. I eased closer and peered into the darkness, seeing nothing.

“It’s ok, I’m not going to hurt you,” I said still brandishing my rolling-pin, and slowly reaching around to the switch. This time I flipped it on and as light flooded the cooler, I looked around, seeing absolutely no one, only racks full of food.

I braced the door open and began picking up and moving my supplies into the cooler, keeping a watchful eye. As I turned to leave and reached for the switch, it clicked off, on its own. A coincidence I told myself as I hurried out and shut the door.

I knew no one had walked past me while I loaded supplies into the cooler, but I searched the restaurant looking for the intruder.

The place always took on an eerie silence when it was empty after dark, which I had grown used to, and usually welcomed it after a long busy day. I was always here late preparing things for the breakfast crowd.

The restaurant was a renovated underground basement, beneath an old rock building full of little rooms which had been renovated and filled with stores designed to delight any shopper. Noises like pops, creaks, and whines from the old wood, rock, and metal reacting to temperature changes and wind whistling through old cracks and crevices were normal. In the late hours, the building had a life of its own, with a full chorus of sounds.

I had listened to the old building speak to the night in its usual way as I worked. Sometimes this seemed like being an eaves dropper on a private conversation. This particular evening while I worked, this conversation had seemed even more animated as though some sort of real excitement were being discussed. The wind howled outside, branches scraped against windows, the tin awning above the outside entrance popped and complained as the temperature cooled, and the wood stairs creaked as though they still bore the footfalls of the day. My small noises as I put away cooking pans and shoved boxes seemed loud in the absence of other human noises, but the building seemed as though it were trying to be heard over me tonight. I had become lost in my own thoughts.
If I had been truly present in nature’s conversation on this evening, I would have realized sooner, that the building had gone from highly animated to quiet. It had ceased its conversation, as though in hushed stillness we both waited to see what I would find.

It came in the form of blackness, as every light in the restaurant went out. I moved toward the light switch by the back door where shallow light filtered down the outside stairwell from a street light a few yards away. Just as I reached for it, the light nearest me came on, followed by each light across the restaurant, one by one.

I turned to walk back into the kitchen, watching the lights resume burning; there on the floor in my path set one of the very frying pans I had previously put away. I picked it up glancing around as I did, “Ok, who is here?” I laughed nervously, “Come on, show yourself!”

As the last lights came on, I saw him walk toward me dressed in an old style, gray pen stripe suit and a black top hat. Just for a fleeting second he was there, and then he was gone.

There was the sudden loud crashing of several pots onto the tile floor in the kitchen. I turned in time to see the last of them fall from their shelf as though someone had swept them off from one side to the other. I saw no one there to have caused their descent. I rather cautiously began picking them up and replacing them on the shelf. As I placed the last one back in its spot, another one fell, just missing my head. I tried putting it away several times and each time it clattered past me to the floor.

“Alright, so you don’t want that one up there. How about we just leave it on the stove?” I asked setting it on the nearest burner. As I looked up, I was startled to see him standing next to me. He reached and moved the pan from the front burner to the back, and then took two steps away and disappeared.

I stood still, waiting. Then five minutes after his disappearance, the building resumed it former chatter.

I finished my work looking over my shoulder all evening and then went home. The next day the pan I had left on the stove, had been put away again.

“Thank you to whoever put the pan away that pan I left it on the stove last night,” I said.

“There wasn’t a pan on the stove when we came in,” was the unanimous response.

One of the other cooks stopped and gave me an earnest look, “You met him, didn’t you?”

“Met who?” I asked, not sure I wanted to share the previous evening’ events.

“Dr. Fritz, our resident ghost,” he answered.

I said nothing.

During that day, the good doctor, took a special interest in me. He moved my cup and hid my spatula. Sometimes he would even lay the utensil I was searching for by my side for me to find. I even saw him walk by a few times, as did other staff and even some patrons.

That evening I found myself alone again. I was cleaning the stove which still had hot food on it when he appeared in a rage and threw the pot and its contents at me, and I barely had time to dodge the mass of it. I tried to ignore this and just clean it up, when he shoved another thankfully empty pot off the shelf above onto my head.

As I stood up from cleaning his mess, I realized there were several other ghosts walking the premises. Each wore white gowns that tied shut in the back and they appeared to be searching for someone or something. He was watching them too, looking distraught. Occasionally it seemed they spoke to one another in passing; mumbled voices I could hear, but not understand.

As I worked, they all disappeared again, and it was only him and me. He sat with his head in his hands at a corner table, ignoring me, which I welcomed. I finished my work and left that night.

He greeted me and some of my staff early that next morning with a glass bowl crashing at our feet as we entered the door. Several of the other ghosts were with him. He moved from one to the next to the next as though observing them. At least it was a slow day, but I noticed that these other ghosts, appeared to be patients still dressed in hospital gowns, perhaps whom the good Dr. lost some many decades past, and they seemed to account for his mood.

Some of the patrons observed theses ghosts walking right through tables as though nothing was there. Others would lie down on the tables as though sleeping and simply disappear. None of our regular customers seemed anything but intrigued by all this, leading me to believe I was the last to know of our paranormal friends. The dishes crashing in the kitchen, only mildly startled any of our customers.

I was sure they thought we were really having a bad day back there, and I supposed we were. A bad mood day for the ghost doctor resulted in our subsequent hardships. Before the evening was over I had to get stitches from the cut a large chef’s knife had left across my arm when it sailed through the air at me. Luckily the last of our customers had left just before this happened. Perhaps a courtesy he afforded us.

I have found that the customers come here because they are fascinated with eating where the dead still walk the rooms.
Why do we all still work here? Why not find another job you might ask? The question is, why leave? The good doctor is temperamental, but he hasn’t lost a patient in 100 years, which makes us relatively safe, except minor mishaps of his moods. And the ones he lost are still walk the floors of a century old renovated hospital morgue, known as The Final Fare Café.

Happy Halloween all! Hope you have a fun and safe night!

September Highlights- Fredericksburg’s STEM/Rocket Program

The school year is now into it’s seventh week. September has come and gone and the Fredericksburg High School STEM Academy has been working steady at all levels. Each group has new skills they are learning, goals they are working to achieve and events they are working towards.

Mr. Matthes says that, ” The Freshman are great! Already I have seen an improvement in their presentation skills. They have also been successful in finishing the structural engineering fix for the SystemsGo launch tower, and have followed up with a PMA (post mission analysis) and current event report.”

This is the second period Freshman class with their structures. Students including in the picture, in no alphabetical order are as follows: Jowad Aysheh, Gloria Burns, Luke Duderstadt, Manuel Enciso, Jack Fox, Jack Gallagher, Jacob Hinterlach, Thomas Johnson, Troy Kneese, Aquilino Perez, Zoe Rivera, Darien Robles, Jessen Stableford, Noah Stotz, Deja Turkett, Alek Vasquez, Calissa Vollmar, Dalton Waters, Joshua Wienecke, and Zachary Willis.

This is the third period Freshman class with their structures. Students including in the picture, in alphabetical order are as follows: Dylan Ahrens, Jarrett Beard, Jorge Giral, Blake Boubel, Chad Braden, Jacob Brown, Esten Cooke, Samuel Cowsar, Ryan Davis, Gavin Eckert, Tucker Elliot, Frank Fackovec, Cathryn Huff, Brendon Huynh, Abel Jaimes, Ryan Majors, Antonio Martinez, Tristan McDonald, Gabriela Moreno, Robert Sanchez, Landon Sparrow, Carl Wilger, Lane Wallendorf, and Landon West.

The freshman will be traveling to several companies to investigate how engineering plays a part in their industries. This will take place over the next three months in three separate trips. Included in these trips are: Caterpillar Manufacturing, Aqua Power Cutting, Soutwest Research Institute (SwRI), Toyota Manufacturing, and Center for the Intrepid, all out-of-town trips, and Fischer and Wieser, Heartland Enterprises, Ltd. , Swissomation, Kager Industries, and Rode’s Iron and Pipe locally. During the month of October they will visit Caterpillar Manufacturing and Aqua Power Cutting.

The Juniors are currently working in the R&D (Research and Development) element of the curriculum after having completed building and launching their Generation 1 model rockets. During this phase they are working on modeling the motor burn.

Junior class with the Generation 1 rockets.

Seniors are alternating between rocket history and work on the test stand and testbed. They are currently in a break from the history but will rejoin it in a couple of weeks. Mean while they have conducted successful CDR’s (critical design review) for test stand that generated positive and developmental feedback. They have also had success updating the testbed. Wiring and programming issues have been corrected, they were able to create a new tank system which will increase safety in the fill and weigh of nitrous operating systems, as well as succeeding in making the testbed more frictionless. Their senior rocket is still in the works as they continue in the design development of the vehicle.

New this year, the seniors created rocket history children’s books. Students will be doing recordings of themselves reading the books, and both the books and the audios will be sent to the Fredericksburg Elementary School where students there will be able to read the books and hear the high school authors read the books to them.

According to Mr. Matthes, “Their rocket history children’s books were awesome!”

On November 7 & 8, the senior group has a chance to go to the NASA Johnson Space Center, for flight profile reviews, grant updates, and a possible preliminary design review. Three students will go for sure, and those will be named at a later date.

Seniors, here is your challenge for the month, according to Mr Matthes, “If you complete the analysis of historic test data from the teststand then you will all be eligible to attend this trip. He would like to see that happen and take you all. Can you meet the challenge? Next month’s edition of this article series will publish the answer to this challenge. Now is your chance to show my readers and Mr. Matthes that you can meet the challenge.

This article is the second in a new series of monthly updates that will follow the Fredericksburg STEM Academy/Rocket program. This school is a participant of the SystemsGo STEM program. This series of articles is intended to support, encourage, and challenge students in the program as they share their working status and accomplishments throughout the year in the program. These publications will be available for tags and re-posting.
