Students use a purchased calorimeter or make their own simple calorimeter to measure the energy content in selected foods.
Students estimate their own energy output during different forms of exercise.
Balancing energy input with energy output is important to our personal health. Humans are consumers in food webs. Construct graphic organizers, draw cartoons, make a collage, perform a skit, or compose a song. Communicate through written and oral expression. Measure mass and temperature and determine the relationships between temperature changes and heat energy in foods.
