Day 28: Using TIPERS to Review Concepts From Last Year

Since my AP Physics C students had AP Physics 1 last year, I’ve been using TIPERs as a way to reintroduce and review the AP Physics 1 topics we’ll be expanding upon this year.

Day 27: Speeding Up and Slowing Down

Students used video analysis to generate the shapes of position-time and velocity-time graphs for a 5 different fan cart videos. We used flash version of the videos, so the analysis was done right in the browser, no need for Logger Pro. The videos are available at the RIT Live Photo Physics website here: http://livephoto.rit.edu/LPVideos/fan/

Day 26: Calculus Without Calculus

AP Physics C students are writing VPython programs to estimate the electric field due to their choice of: rod of charge, arc of charge, or ring of charge.

Day 25: Always, Sometimes, Never — Acceleration

This proved to be quite difficult for students, but generated some good discussion.

Day 24: Including Δv Arrows On Motion Diagrams

This year, I’m taking a cue from Eugenia Etkina and having students draw Δv arrows on their motion diagrams. It’s a nice scaffold for drawing acceleration arrows correctly.

Day 23: Practice Quiz

One new thing I’ve been doing this year is giving practice quizzes before the actual quiz. Thanks to SBG, I have acquired several different versions of each quiz over the years. So I just pick one, hand it out, and post the solutions online. Students seem to be more prepared for the actual quiz and fewer students need reassessments.

Day 22: Motion Shot + Lensmob = Introduction to Motion Diagrams

Students used the Sony Motion Shot app (iOS/Android) to create time-lapse photos of the following motions: fast constant speed, slow constant speed, increasing speed, and decreasing speed. They then emailed the photos to my Lensmob photo album so we could see and discuss everyone’s photos. (I set up an album for each period.) This was a nice lead-in to motion diagrams.
