AP Physics: LOL Diagrams
Students went from bar charts to full LOL diagrams today. I am really coming to appreciate one of the worksheets from the Modeling Instruction curriculum that has students make LOL diagrams using several different systems for the same scenario, which really nicely illustrates why identifying your system matters. Students took to this easily enough that I think bar charts and LOL diagrams are a spot where I can pick up the pace a little next year.
Physical Science: Motion Detector Lab
Students walked in front of the motion detector to reproduce the graphs they worked on Friday. Since we ran out of time on free fall day, I also showed a clip of Brian Cox when he visited a giant vacuum chamber to drop a bowling ball and feathers.
