I’m happy to announce the return of my student-designed Phunsics class for the 2013-2014 school year. If you’ve followed our previous work, you might want to skip ahead to phunsics2013.wordpress.com or the pics below to see what we’re doing at the moment. For some discussion of how I set up the class this year, read on.

As in my experiment a couple years ago, I’m running my physics class as a student-organized maker-space where the teacher’s main role is to check for safety and procure supplies as needed. The projects and course topics are mostly up to what students are interested in building, making, and learning about in the field of physics and engineering.

I added a bit more structure this year compared to the last time I ran this class. We once again started off with the marshmallow challenge on the first day. This was awesome for having students experience failure and the need for prototypes in their projects. We then spent a day or two brainstorming three areas:

    1. What content knowledge and skills should we expect to learn/want to learn as part of this physics class?
    2. What tools will we use to communicate what we are doing with our families, friends, school, and world?
    3. How will our work be assessed and graded for the school’s online gradebook?

The class of 26 students broke themselves up into teams to tackle these three areas. One group dove into our physics textbooks and the AP Physics guidelines to begin to search for big ideas for the class. A second group started brainstorming what sort of online sites they wanted to use for sharing their work. The third and surprisingly large group (I was sure no one would want to talk about grading policies) had some great conversations about how they wanted the course grade to be determined.

Initial tasks for setting up the course: content, communication, and grading policies

The results from our initial discussions about how to run this year’s course

After a few days of research and discussion, students came up with these guidelines for the course:

    • We will use a class blog at phunsics2013.wordpress.com and a shared YouTube channel to display our work
    • Each project group will have at least one author with a WordPress account who can publish to the class blog
    • Groups may create their own separate blogs/sites but will post links to these on the class blog
    • A reference list of major course topics will be published to the class blog by the team investigating our list of content knowledge and skill standards
    • Each project group will publish a weekly update to the class blog for the purposes of communicating and documenting their progress
    • At the end of each week, each group will either email or have a conversation with Mr. Ludwig about what progress grade they have earned for the week as supported by the evidence in their blog posts
    • All projects will be shared with the community both in online spaces and in at least one public event similar to our Phunsics Day 2012

What’s really fun is that their policy about weekly progress checks to determine their grade is very close to what I’d already implemented in my other classes using a weekly student entry in BlueHarvestFeedback. Either my students have caught on to how I like to grade or I’ve stumbled upon how they like to be graded, but either way we’re on the same page with our progress grades. I think we’ll need to have some more conversations later about how to derive their semester grade, but for now the progress checks are working nicely.

And now for the best part->

Here are the projects that my students are currently working on:

  • designing and building a quadrotor flying machine
  • a raspberry pi-powered robot of some sort (battle bot would be ideal, but we’re just learning how to program the pi)
  • the physics of weightlifting using Vernier Video Physics motion analysis
  • designing and building a spinning magnet and ferrofluid apparatus
  • building a flame tube for visualizing different wavelengths/frequencies of sounds
  • designing and building a two-seater powered go cart
  • designing and building a two-person cardboard boat destined to row across the swimming pool
  • restoring and improving the class hovercraft

Its early in the year, but many groups have already had some important successes. It’ll be interesting to watch as the year unfolds. Stay tuned and follow their blog for updates!

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.

hover-tree
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.
