Use a fast response temperature sensor to investigate and compare the energy content of four different food items: marshmallow, popcorn, peanut, and cashew.
Students investigate and compare the energy content of energy-rich substances (foods) to determine:
Students measure the energy released from different types of foods by oxidative combustion (burning) through energy transfer into water in a closed container (calorimeter). From this they:
Aluminum pie pan 4
Aluminum soda can 4
Cardboard box, large 1
Electronic balance - 1 per class
Food samples: marshmallow, popcorn, peanuts, cashew - 1 each
Graduated cylinder, 100 mL
Large base and support rod
One-hole rubber stopper, ~1 1/2"
top diameter - 4
Paperclip, large - 5
Rod and clamp
Tape - 1 roll
Water - 200 mL
Wooden matches (or starter wand) - Several
This experiment may require software and an interface for data collection.
