MS Science & Engineering Expo 2018

The annual Middle School Science & Engineering Expo was a huge success once again, thanks to the hard work and positive attitudes of so many students, parents, teachers, and staff. This year's theme of The Human Machine inspired a range of hands-on explorations, from Masa and Cameron's tennis and baseball clinic, to Heidi and Ella's eye dissection, to robotic prosthetic hands built by the Intro to Engineering class.

Mr. Alker worked hard with every 8th Grade student over a period of several weeks to hone their demonstrations to perfection. With such a rich inspiration as the human body itself, students were well able to explore athletics, biology, physics, and engineering.

Never too young to begin!  Providence class of  2033?

Architectural Competition in Santa Ynez

If you had been lurking around the Upper Campus at 6:55 am on Tuesday the 13th of March, braving the rain and stumbling about in the dark, you might just have caught sight of a strange and unusual thing: eight high school students and one teacher loading up into a white van. Wielding scale rulers, plastic triangles, and mechanical pencils, these intrepid adventurers had only two things in mind—the Santa Barbara High School Architectural Competition, and a desire for strong coffee.

Victor, Gabe, and Trevor: together in life, together in architecture!

All grades were represented in the group: Tys (our sole senior); Eva, Gabe, Josh, Trevor, and Victor (juniors); Peter (sophomore); Josh (freshman). They arrived at Santa Ynez Valley Union High School, and quickly found their way to the gymnasium. Along with about 50 other high school students from Dos Pueblos, San Marcos, Santa Ynez, Dunn, St. Joseph's, Santa Maria, and more, they listened attentively as the design challenge was described.

Josh and Peter read the design brief carefully as the

competition begins

The challenge: to design a new fire station that would be both functional and attractive, having a natural "park-like" feel. Constraints were given as to fire truck bay dimensions, equipment lockers, living quarters requirements. Particular difficulty lay in the small size of the property described. Not to be fazed, the students launched into it with gusto!

This competition has been running annually for the last 27 years, conceived and managed by David Goldstien from the Architectural Foundation of Santa Barbara.  Recent winners have come from Dos Pueblos, Laguna Blanca, St. Joseph's, and Dunn. This is the first year that Providence has entered the competition; David reached out personally to our school this year to make us aware and extend his invitation.

Tys, Eva, and Josh working hard and enjoying the day!

It was a long day of creating professional-style scale drawings (site plan, floor plans, and elevations), but the students all agreed that the seven hours had flown by, and they could have done with just a little more time! Gabe commented that this was the "the best icebreaker you could do to get into the world of architecture." Trevor noted that the whole experience "helped us understand how to spend time wisely."

The entries were judged on the same day by practicing architects, and within 24 hours we received some good news: Josh and Gabe had both placed in the top twelve, and were asked to present their designs to the final panel at the Alisal Guest Ranch!

In the end, the competition was won by Vivian from Dunn School in Los Olivos. Vivian has placed amongst the winners in years past, and so was well prepared to take the lead. However, our congratulations go out to all of our eight students, and especially Josh and Gabe, who represented Providence so well in their very first attempt. A supervising teacher from Santa Maria commented on the difference that our students exhibit: her students have commented that they want "the Providence confidence!"

Josh and Gabe proudly stand for a photo at the Alisal

The Providence Engineering Academy teaches many different aspects of design and engineering, in its pursuit to "inspire and equip students to find creative solutions to the world's problems through mathematics, science, and engineering, as imitators of a creative God." Architecture is but one of those many exciting elements, and we congratulate all of our participants for their creativity and hard work.

Gliders: In Production!

A quick update on our Advanced Engineering II glider project: the students are currently hard at work translating their theoretical calculations into hand-made reality. The problem is at first daunting; how do you create the various parts of a flying machine, according to a specific design? There are dozens of materials that might be chosen for each component, and the production needs to be accurate enough and cheap enough and quick enough and repeatable enough!

in place, ready to glue

All teams have settled on a 3D-printed rib-and-spar design for the wings, although the exact rib profile varies in size and shape. All teams are using carbon fiber square tubes for the spars (the long beams that run through from wing tip to wing tip). Some teams are planning on skinning their wing with cellophane, and others are planning on tissue paper and dope (a kind of glue that tightens and hardens the paper).

Kylie and Josh and Luke are producing
the largest, thickest ribs of all teams
(sounds delicious, in fact)

To see some interactive CAD models that Tys and Mikaela and Colby and Victor are working on, click here.

Other components, such as the undercarriage and fuselage and tail, are being made from 3D-printed parts, balsa sheets, more carbon fiber, and even colorful pipe cleaners.

advice from our classroom mentor

To help with the design process, we asked retired aerospace engineer Dr. Nathan Gates to visit our classroom. Dr. Gates moved around the different teams to consult with them. Each team explained their design, and received valuable feedback as to their construction plans. Dr. Gates' area of expertise was structural mechanics; he was doubtlessly overqualified for this role!

wing design

To further sweeten the deal, we also asked Willow Brown, Providence alumna (2015), to come by on the same day. Willow's sister, Kylie, is on a team with Luke and Josh. Willow is currently studying mechanical engineering at Loyola Marymount University. Did this give Kylie and her team an unfair advantage? Only time will tell.

The maiden voyage is fast approaching, so watch this space. There's more coming up later this year, too—students will design, print, and build quadcopter drones. Stay posted, and thank you to Dr. Gates and Willow!

In the Steps of Orville and Wilbur

The Advanced Engineering II group has a unique and challenging task in front of them. In fact, it is quite possible that none of the students has ever undertaken something quite like this: a group project that lasts from September to March—designing and building a model glider!

The students have been hard at work learning the fundamentals of aerodynamics, as applied to conventional aircraft. They understand Bernoulli's principle, the momentum shift theory of lift, what induced drag is, and why most modern aircraft have those little turned-up ends on their wings. They know the value of the theoretical lift curve slope, and how much lift an uncambered airfoil produces at a zero angle of attack, and they can check it all in a virtual wind tunnel test! Impressed yet?!

as they work on the detailed design spreadsheet

Divided up into four teams, the students have just put the finishing touches on their complex design spreadsheet, which describes in precise detail the various features of the glider they are going to build. Each glider will be thrown from the top of the science lab building onto our field, carrying a single (unboiled!) egg to safety as far downfield as possible. The plane that successfully flies the farthest and lands safely wins!

The students will be using a variety of materials and techniques; we are currently amassing a stockpile of carbon fiber tubes, balsa wood pieces, tissue paper, cellophane, lead weights, aluminum wire, and other bits and pieces. The teams are creating CAD models of their wing cross-sections, intending to 3D print them in the coming weeks. Most of the gliders are about three feet across the wingspan, about two feet long, and weigh a bit more than half a pound. (By the way, all of our work is done in metric units, to be in keeping with international physics standards!)

In order to get a real hands-on feel for the work, the group also took a special visit up to the Santa Ynez Airport, where they were shown a variety of gliders and powered aircraft. This was the perfect chance to connect theory to practice, and it no doubt helped inspire the students as they move into the manufacturing phase.

Dave and Colby, employees of the airport, graciously showed us around the couple of dozen light aircraft sitting on the runway, answering student questions about wing design, gliding techniques, and the pilot license process.

the gliders

Cirrus light aircraft

As more airplanes took off and landed around them, the students got up close views of a shiny Cirrus, many older Cessnas, and an unusual-looking Long-EZ. Colby described to us the great thrill of flying, being in perfect solitude up in the sky; he is working towards his powered pilot license.

Is it a spaceship of some sort? The Long-EZ design is not
recommended for the students to imitate for their glider design

With plenty to fill their heads about glide paths, turbulent flow, night navigation, wing construction, parachutes, and fuel pods, the students took one final pose on an aircraft they were allowed to sit in! Thanks very much to Dave and Colby and all of the crew up at Santa Ynez—perhaps we'll see you again sometime soon! Airport Day is coming up on Saturday, May 20th, and all are welcome.

Educational Design Project

In the Providence Engineering Academy, we emphasize the idea that technology ought never to be an end in itself. Technology for technology's sake rings hollow, and as Christians we ought to see all things as being good and useful for God's kingdom purposes. A very real question for us is this: how can we use engineering, design, and technology to love others? As engineers, are we perhaps able to serve others in ways that others cannot?

In answer to this question, the 9th/10th Grade Foundations of Engineering I class asked for and received requests from our school's own teachers and staff. We asked them what they could use in their classrooms and offices that we could design and then 3D print. In the past, the students have produced models of ziggurats, pyramids, and Solomon's temple. They have made gear ratio demonstrations, ten-sided dice, and computer monitor stands.

This year, the entries were just as exciting. We start with several geometric demonstrations for Mrs. Smelley, our 7th and 8th Grade mathematics teacher, designed by Ava and Peter. Ava created some simple trapezoid area demonstrations, as well as a cubic volume demonstration. Peter built a folding box that opens up to show how a 2D net is created from a 3D shape. Mrs. Smelley was delighted, telling the students "you have really supplied the tools for our class."

Next up was Sam, with his large model of a cell for Mr. Alker's middle school biology class. Sam created each piece as separate, so students can pull it apart, and really "feel" what they have seen in the textbook.

Todd produced a somewhat unique request: an anti-theft device! Mr. Hurt finds that his classroom calculators tend to go "missing", and so he is embarking on a social experiment. Will fastening a distinctive 3D printed science-themed design to the back of them change the outcome? Only time will tell. At the very least we appreciate this practical use of the scientific method.

Todd's design features a striking gold-on-black circuit board pattern

Next in line is Caleb, who designed something along more structural lines: a replacement door handle for a cabinet in our science and engineering lab. This project was a good lesson in meeting external constraints; it had to be strong enough, match up with the existing screw holes, and allow for screws to actually take hold of it. Caleb also added some extra pizzazz.

The new door handle, with Providence logo, in place and ready to go!

Madison designed some calendar labels for Mrs. Penton, enabling her to easily highlight different events as the year rolls by. The labels are removable and have pre-printed words on them for common activities and events.

Mrs. Penton shows off her new designs!

Ben also went the structural route by creating some shelving brackets for Mr. Meadth. Why go store-bought when you can have custom-made? Mr. Meadth greatly appreciated Ben's creativity, as he created dozens of "bubbles" and carefully placed holes to match up with the existing bolt locations.

Ben's brackets support a display shelf for the Calculus class

Pedro helped complete a design that was begun last year by 11th and 12th Graders. The idea was to build a column compression demonstration, showing how compressed columns form a variety of buckling modes, depending on end fixity conditions. Pedro adroitly designed a sliding attachment, which keeps the end of the column from rotating while allowing one-dimensional translation. This will see use next year in classes!

The column testing device is finally
complete, thanks to Pedro

Alena chose to work on the Engineering Academy keychains for next year. We have a tradition of producing simple keychains for everyone in both classes, and Alena is working on something that echoes next year's themes of robotics and structural engineering.

And finally, Josh designed a caddy for Ms. Svoboda in middle school. Ms. Svoboda teaches between different classrooms, and this caddy allows her to quickly bring some essential items for her afternoon class. In this case, Josh worked to supplement an existing file holder with customized attachments. Ms. Svoboda was delighted with the results!

Have caddy, will travel!

As a final word, Mr. Meadth and Claire (our 11th Grade T.A.) also worked to produce some pieces for the Providence Preschool. Our new director, Cheri Diaz, wanted some "natural" items, so we printed a starfish, a seashell, a honeycomb, and some ice cubes (all but the ice cubes were found online on Thingiverse). We hope the children enjoy playing with them!

MS Engineering: The Final Challenge!

Wow! What an incredible display of robotic strength and fortitude! Mr. Meadth would like to thank all of the eighteen middle school students who worked so hard and waited so long to show their programming prowess. Many thanks also to all of the many parents who came to watch.

bot of them all!

After a gripping round of preliminaries, it was clear that Jon and Ella were not to be beaten, consistently needing only 43 seconds both times to get all three cubes in the goal. Ryan and Gideon zoomed down the line with double wins, as fast as 37 seconds. Kassy and Miranda took it slow and steady, but won both matches with an average of 2:19. A special qualifying round also put Liza and Kaitlyn through with their prize horse, with a record-breaking 18 seconds!

In the elimination round, Liza and Kaitlyn beat out Jon and Ella with a lightning-fast 21 seconds. The secret? High speed gear ratios, where Jon and Ella stuck to direct drive. And in a stunning upset, Ryan and Gideon lost out--despite their high speed gears--to the perfectly consistent Kassy and Miranda, who beat their previous times by over a minute!

Mark and Tzevon designed a conveyor belt to
get their cubes in the box

Jeffry and Audrie went for the "tall tricycle" design

In an all-girl final round, Liza and Kaitlyn made the first drop. But they fumbled the second, and Kassy and Miranda faithfully dropped theirs in the box to equal the scores. A couple of unforced errors, some bouncing out, and the scores were again tied at two all! In the end, however, nothing could stop the speed and accuracy of Liza and Kaitlyn, who wrapped it all up with an impressive time of 49 seconds! Well done, girls!
