Allowed redo on test.

Asked students to sit next to a partner they wanted to work with. Allowed students to work in their pairs and redo the same test using any notes and the yellow textbooks. I told students I would average the two test scores.

When students were done, I showed the 10 Gary Williams energy symbols and asked students to match them to the appropriate forms of energy. Explained the difference between potential energies (blue rectangles) vs energy transfers (green boxes with points.)
