Day 119: Whiteboarding & Mineral Intro

AP Physics: Whiteboarding

Students whiteboarded their results for the Ohm’s Law lab and an electric potential difference activity I had them try in yesterday’s sim. Students plotted voltage vs. resistor with the multimeter’s ground probe in several different positions to see the change is always the same. The analogy between gravitational potential and electric potential doesn’t seem as clear for my students as in the past, so next year I might go back to having students map electric potential.epd

Earth Science: Mineral Stereograms

I did a few notes on what caused the early Earth to melt and form layers. Afterward, students spent some time with books of stereograms of rocks, minerals, and gemstones. I wrote some questions to get students thinking about the key characteristics of each category and it was fun to listen to some of the things students were noticing.
