Day 73: Coulomb’s Law & Reaction Types Lab

Physics: Coulomb’s Law

Students used fur to charge a pair of balloons hanging from a meter stick, then measured the angle the strings were at as a proxy for the force. They then collected data to find a relationship between the force the balloons exert on each other and the distance they are separated.

Chemistry: Reaction Types Lab

I borrowed a lab from the Modeling Instruction chemistry curriculum where students actually carried out reactions of each type, and  made some observations to connect the reaction equation to what actually happened in the lab.
