What do you do with a physics class full of bright, independent, high school kids? Well of course you
march through the physics textbook so they can learn how to plug and chug all the right equations turn the class over to them so they can do the experiments that they want to do. At least that’s the way I thought we’d try it this year in my admittedly experimental foray into teaching a full-year physics course again. We had an awesome first semester, with lots of small student groups that self-organized around a number of major projects such as the trebuchet, hovercraft, hot air balloon, potato “accelerator,” wind tunnel, Road Runner/Coyote video analysis, and multi-stage rocket (and Barbie launcher) design. We capped off the semester with a traveling physics hover-tree built by the students that was decorated with mementos of all their projects for the year so far and lit with whatever light bulbs we could find, including a car head light.
The tree was quite the conversation piece once we parked it in our school’s common area/cafeteria, but more importantly it let the whole school community get a glimpse of what the students had been up to in our physics “workshop.”
On the first day back from Christmas break, with the hover-tree mysteriously removed back to our workshop, I challenged the physics kids to make a switch for the new semester. I explained, and they agreed, that the first semester had been “about us.” We had done all the fun, dangerous, and occasionally goofy projects that were at the top of our to-do lists, or in some cases our as-seen-on-You-Tube lists. It was time now, I said, to change the focus to become “about them” (insert image of me pointing outside the classroom) meaning that we should take on projects that would be either educational for younger students or benefit the entire community in some way.
And so Physics Day was born. Physics Day will be happening on March 31st from 10:00 to noon in our gym and the nearby parking lot. We’re going to demonstrate the trebuchet, rockets, potato accelerator, and the hovercraft. Inside the gym we’ll have several stations with hands-on experiments such as wind tunnel testing of objects, slime creation, electromagnet building, an alternative energy showcase, and maybe our Rube Goldberg machine if we get it done in time. We plan to distribute promotional fliers around town, especially to students at our Intermediate and Jr/Sr High schools. We’ll publicize it in our local paper, too, as the day gets closer so that all the great folks at the local hardware stores can come see what all their lumber and pipe get used for.
Student designed, planned, and performed. Completely. I can’t wait to see what sort of turnout we get. I can’t wait to see how the trebuchet team manages to move the trebuchet halfway across the school grounds. I can’t wait to see if we can inspire students to enjoy science again.
P.S. —The student brains behind the trebuchet are at work on a plan to provide free Internet access to students at home throughout town by bouncing the school’s WiFi signal off of some strategically placed reflectors. This may be the “about them” message taken to the extreme, but if we pull it off, it’s going to be a big deal for the whole town. I’ll share more on that as it progresses past the ugliness of setting up the backend RADIUS server.
