TOPS #15 Heat

Your students will study heat in all its forms: how it conducts through metals and nonmetals; how it convects through water and air; how it radiates through space. Test tubes of water wrapped in shiny foil or dull black paper lead students to conclusions about heat absorbers and emitters; cooling curves reveal the best insulator and the best conductor; a jar of moist sand demonstrates the greenhouse effect. Whether heat is supplied by their own hands or a burning peanut, your students will discover that mass and temperature both count when computing calories.
