AP Physics 1: Standing Waves
Students used Pivot Interactives to find a relationship between wavelength and frequency for a standing wave. Students had trouble with some of the vocabulary and with visualizing one wavelength; I usually start with a day of qualitative observations with snakey springs, but skipped that to make up for the week our school was closed. Students were still able to figure out what they needed, it just took a little more coaching than usual.
We had some discussion to brainstorm what could impact the period of a pendulum, then students went to work collecting data. There was some good discussion of how much variation was enough to matter when students were working on angle and mass.
Chemistry Essentials: Formula Writing
Students practiced translating between names, formulas, and particle diagrams. We got out some beans to use as manipulatives in simplified Lewis dot diagrams to help make ionic bonding a little more concrete.
