Today we graded log 4 q2. We then moved on to started our indirect observation Clay Atom lab.
Here we are using indirect observation to try to figure out what is in the center of a ball of clay using toothpicks as probes. We are in a small way simulating the experiment that Rutherford did to understand atoms. He took Thomson's model and set up an experiment that projected alpha particles at a foil of gold. Here is a video on Rutherford's experiment to help explain this.
