Context for Use
Student will work in groups of 3 or 4, depending on class size. They will need to use a light so they will have to have access to an outlet.
Description and Teaching Materials
Each group will have three cans. They will paint one black, one white and leave one plain. Using styrofoam, trace the top of one of the cans to make a lid for each can. Fill the cans with an equal amount of water then take the temperature. Place the can an equal distance from the 150-watt light and then watch the temperature. Students will record the temperature every minute for 7 minutes. Once they have collected all data, students can then graph the information and compare the results.
