What is heat energy, where does it come from and how does it relate to chemical energy? Heat & Chemical Energy teaches students that heat energy comes from the motion of chemical atoms, and chemical energy is stored in the bonds that link atoms together. Discover how chemical reactions can give off heat energy and how heat can help release the stored chemical energy in fuel. Learn how heat travels through engaging demonstrations that illustrate the methods of conduction, convection and radiation. Students investigate how scientists measure calories -- the energy stored in food -- by constructing a calorimeter and burning a peanut.
