Holt Modern Chemistry: Energy Content of Foods
This probeware Lab Energy Content of Foods from the chapter Causes of Change uses a temperature probe to calculate the temperature change of the water to determine how much energy was released when food samples burn.
Read the entire lab (Teacher Resources PDF file), plan what steps you will take and setup the equipment as described.
Make copies of the Lab PDF file for your class.
Make sure DataMate is on all student calculators.
