Unit on the Earth's atmosphere focusing on Conduction, Convection and Radiation. Students define the terms in a foyer box (examples and pictures). The next part is a description of the way those 3 types of energy heat the earth's atmosphere. The independent practice is to sort out 10 different "activities" to decide whether they are are conduction, convection, or radiation. There is a multiple choice exit slip - great for data. Answer key provided at the end.
