Day 100: Accelerating at a Constant Velocity

Friday, 29 January 2016

Student asked me today about how a net force causes an object to “accelerate at a constant velocity”. I asked them to explain what they meant and we arrived at the data table on the right. A classmate quickly edited the original kid’s words to ask about an object “accelerating at a constant rate”.

 

Day 99: FRC Business Team

We have a big deadline for the robotics team in a week: submitting for the Chairman’s Award. Today, we met with two outside mentors to outline the activities we’ve done the past year that are award-worthy and outline the essay itself.

The essay’s going to be drafted during a work session on Saturday.

Day 98: Assuming Prior Knowledge

Wednesday, 27 January 2016

I’m amazed at how quickly we could get to free body diagrams when I assume the kids remembered something of their physical science class last year. We’re already talking about the motion-related implication of balanced forces.

Today was the first day of 2nd semester for 2/3 of the classes I teach. Above is from one of them. I asked the kids to also list out all the types of forces they knew about, to tell me what they remembered of Newton’s Laws of Motion, and to roll a bowling ball across the tile foyer of our science building (all to prove we have few Jedi among us who can move the ball after it leaves their hands).

Day 97: Easing Into 2nd Semester

In other news, I kicked off spring semester with two games: Extreme Rock, Paper, Scissors just for fun and Paper Airplanes to disguise the assigned seating process. Paper Airplanes isn’t at all a grouping game, so I put a tiny, inconspicuous colored dot on each paper. Five colors for five tables. Kids got random sheets of paper, played Paper Airplanes and afterwards, I told them to locate the color and group up. Once they find their table group, they pick which table they sit at.

After, we rolled a bowling ball across the tile foyer trying to change its path after the ball left our hands. You know, “an object in motion…” Only one kid in class could do it, so we decided he’s a Jedi. Yes, we’re starting the study of forces.

Day 96: Making Way for Snow

About the post’s title: A coming winter storm caused our school day to be cut short by 2.5 hours. Atlanta has a bad history with ice and highways, so I’m glad the governor asked us to all be home by 3pm today, even though it’s only now (5:30pm) starting to precipitate solid stuff.

The last day of JanTerm is the saddest day of JanTerm. We finished building lamps and Alien Projectors, presented the results, and held a “we loved having you in the class” feelings fest farewell. Above is one of my top 3 favorite lamps from the class. These kids found a giant toy C-130 plane at the thrift shop and converted it into an LED lamp.

Below is the circuit I helped kids solder for their alien projectors. If I were going to do this project again, I’d solder two LEDs in parallel so it’d be twice as bright. I’d also like to get some time on the school’s laser cutter for more interesting cutouts.

Big shoutout to the students of Making & DIY Culture as well as my colleague, Robin-Lynn Clemmons. This class was a blast to be a part of. Monday’s an inservice day for us to get grades in order then it’s on to second semester on Tuesday.

Day 95: Making a World

Thursday, 21 January 2016

We had a last minute opportunity to visit the Museum of Design Atlanta (MODA) for their Designers, Makers, Users: 3D Printing the Future exhibit. This post’s title is a reference to something important we learned: 3D printing is moving its beyond rapid prototyping roots. For instance, we learned that 3D printed structures can become parts of buildings.

I enjoyed learning about Easton LaChappelle from Colorado, a 19 year-old who’s designing 3D printable prosthetic hands, seeing Amsterdam’s 3D printed Canal House, and seeing a prototype of the Pancakebot.

Earlier in the day, we visited our Lower School to learn from the Design Thinking teacher, Marlene Getzendanner.

She showed us her cardboard shelving, her favorite maker tools, and a few projects our lower school classmates have done recently.

Above are Marlene’s favorite maker tools used in her Design Thinking class. Clockwise from top:

  • ergonomic hammer with a shorter handle for smaller kids,
  • safety glasses,
  • Japanese saw which has a flexible blade and cuts on the pull stroke,
  • ergonomic drill,
  • cardboard cutting knife,
  • trauma shears which are great for cutting large sheets of cardboard,
  • bar clamps

Above left: We got to play with Little Bits circuits. This was probably the hit of our visit.

Above right: the guts of a greeting card made with LEDs and copper tape.

Marlene is extremely resourceful for her classes. After she sang the praises of dollar stores and thrift shops, the kids were hooked. One project she told us about is taking apart a dollar store fan for its battery compartment and motor.

She uses the components to build circuit blocks to teach the kids. This Instructable describes a similar project. I think I’ll do this next year with my physics students.

Day 94: Making Lamps

We spent a chunk of time today working on our lamps. Above is a floor lamp design that incorporates all sorts of childhood memories. Below, another student’s lamp made from an old miniature skateboard:

In the last part of the day, we began the Alien Projector Project. I worked with half of the class on soldering the LED, resistor, switch, and a battery holder, which looked like this:

Side note: if you’re teaching a maker class, buy twice as many batteries as you think you’ll need. 9V and 2032 coin cells are fast becoming the biggest expense for our course.

Day 93: Making Pro Connections

Tuesday, 19 January 2016

Edit: I forgot to mention that our classmate Chris wrote the school’s highlighted post for the JanTerm blog today. Way to go, Chris!

Today, we had a special guest speaker — Bob Clagett from I Like to Make Stuff. Our intent was to show kids what it means to be a professional maker. He recently quit his job to be a full time maker and YouTube content creator. The kids (and I!) were a little star struck but still managed to ask great questions. We learned

  • the best place to pick up pallet wood (smaller stores like your auto body shop rather than a big place like Home Depot because the latter sells back their used pallets and won’t give them away),
  • the tools Bob uses for keeping track of episode ideas (Trello on his phone and design notebooks he makes),
  • how he transitioned from working for someone else to making his living off of a free video series (it’s a long story but lots of planning went into it),
  • how his videos show the first time he makes a thing (because he doesn’t like to or need a second of most things he builds),
  • and how he gets inspiration for his projects (most start with a real need — the kids loved hearing about the inspiration behind his secret door bookcase project.

Bob was the best possible guest speaker I could’ve imagined. Many many thanks to him for giving up half an hour from his week to share with high school kids!

Asking Bob from I Like to Make Stuff a question.

After Bob spoke, we spent the rest of the day building our lamps. I was busy supervising power tools, including the vertical bandsaw, mitre saw, and a drill with hole saw bits.

My colleague brought in sponge cake to add to the finished LED Matrix Dessert Trays. I got a short video of the finished product:

Real talk here for a minute: the dessert tray project was difficult for the kids and I wouldn’t choose it again for our beginning makers. We had to make a transistor circuit that used 10 transistors, easily 25 jumper wires, and 10 resistors. There was a lot going on! Here’s one of the breadboards last week when we were making them:

That said, the trays we did finish (about 5 of the 12 we started with) turned out great and are quite the conversation piece for students.

We also shared our plush monster creations with the folks at SparkFun and SparkFunEdu (Is this day feeling full yet? I wasn’t exhausted living it but am just writing about it!):

And finally, our hashtag war with another class continues. This from his wilderness survival class:

Hey @megtheteach, whatcha makin' today? Us? We're making fire. As the kids say, NBD. #Prometheus #twsjanterm

Got this in response from us:

Nbd? You caveman. We tool users. #TWSJanTerm @tfmcc18

Day 92: Making a Finished Project

Friday, 15 January 2015

img_20160115_140756.jpg

I have a bad habit as a maker of starting but never finishing anything. Today was the day I applied a little individual discipline and got the kids to finish something. We focused mostly on the Lamp Project as well as the Plush Monster Project.

Above, a table group of students review one kid’s plans for his lamp. This one is interesting — he bought a guitar stand, a batter’s helmet, and a baseball glove. His plan is to hang the helmet as shown and put the lamp inside. The result is a floor lamp. The other group members are giving him feedback on his plans.

For plush monsters, I sat with a group and backed all the way up to threading a needle. We ripped out stitches and redid almost all the work previously done. Pro tip for etextiles: go over working circuits in clear nail polish to lock things down and prevent shorts.

Day 91: Making People Smile

Today was our day to shine — the class sponsored a big game day during afternoon Community Time*. We unveiled our Snookball court and Giant Spoons Game.

Above, the kids show off their creations to interested visitors. Everyone from teachers, to the IT department, to third graders stopped by to see what we’d done.

Hey @tfmcc18, do you have lighted dessert trays in those puny forts? #IThinkWeAreWinning #TWSJanTerm

*a one hour break held afternoons during JanTerm so that kids can spend time with each other. Because we spend all day in a single class, it’s a rare opportunity to cross-pollinate.
