Today, we started our unit on heat energy. Students watched two demonstrations:
1) Wax dots on a metal rod. One end of the metal rod was placed above a candle and the wax dots eventually melted one by one.
2) Three thermometers - one with white paper, one with foil and one with black paper. They were placed under a heat lamp and we watched their temperatures increase. After, the thermometer covered with the black paper was the hottest and the foil was the coldest.
After, students had to make posters explaining each phenomena. They will present next class.
