100
This is the movement of thermal energy between objects that touch
What is conduction?
100
We make things hot by

Your winter coat has what in it to keep you warm?
What is insulation?
200
A natural source of thermal energy
What is THE SUN?
200
This keeps heat in when needed and lets it out when needed (like our homes in summer and winter)

warmer objects to cooler objects?
400
When cooking heat moves from the burner to the food, this is an example of
What is conduction?
400
Sometimes heat is _____________ to keep things cool (think ice packs)

Why are metal pans good for cooking?
They allow the heat to move through them to the food; they are good conductors
500
