Absorbing and Losing Heat (6.1)
Lab Experiment: Heat equal amounts of cooking oil, vinegar, and water at the same time. Why does the temperature between them differ?
Heat absorption: how fast a substance heats up
Specific heat capacity: amount of heat needed to raise 1 gram of a substance by 1 degree Celsius.
Water Can Absorb Heat:
When we learned that hot air expands, we popped a balloon by putting a flame beneath it. Why does a balloon half-full of water not explode over the heat source?
Keeping Warm and Keeping Cool (6.2-6.3)
Insulation Exercise: Design a four-room house with one heating source and limited insulation. Where do you place the heating source? Where do you use the insulation?
Firefighter Guest Speaker: How do firefighters protect themselves from dangerous heat transfer?
Our class enjoyed a visit from Claresholm's Fire Chief, who taught the students about the equipment firefighters wear.
