Physics: Light Intensity
About half of my students were gone for an AP exam today. The students who were here used a flashlight to find a relationship between the area light covers and the distance to a light source.
Chemistry: Exothermic vs. Endothermic Reactions
I introduced students to exothermic and endothermic reactions and we used a PhET simulation to look at the role of energy. Then, students did a short lab where they made observations of these two reactions.
