This lab allows student to practice measuring time and temperature. They will use those measurements to graph the rate of heat loss from an orange.
The lab is a "murder" investigation. Students use the know beginning temperature of the orange and the calculated rate of heat loss to determine what time the orange was "murdered."
Materials per lab group: 500 mL of water, large cup or beaker, orange (or clementine), timer, and thermometer
Prep: Oranges should be heated in hot water prior to student experimentation
