Conduction, Convection, and Radiation

Students learn the definitions of conduction, convection, and radiation and perform a science experiment with different cups to compare how well they insulate against the cold. Once the experiment is complete, students will graph their results and draw conclusions from the experiment. In the alternative student worksheet, all students use the same vessel but each group uses different insulation to prevent heat loss. It also has a different format where students complete the worksheet directly instead of writing it out on another piece of paper or lab notebook.

Be An Energy Star: Electricity Use Assessment

Students will investigate how much energy various household appliances use (using a Kill-A-Watt meter or provided values) and will determine electricity costs in their community. Once they have obtained these values, they will calculate the cost of running these appliances for certain periods of time and compare these costs to other communities. With certain appliances, such as a coffee pot, students will compare the cost of leaving the pot on all day to buying a latte. Students will also explore what the calculated cost of energy depends on in their specific community or region.
