This is a powerpoint for a 3rd grade class about heat sources. It can be used as a game to determine what is a heat source and what isn't. It also discusses insulation.
3. For Example…
An ELECTRIC HEATER is a heat source! It
makes heat and can warm up a
room!
A pair of socks is NOT a heat source.
Though socks can help keep your feet
warm, they don’t make their own
heat. They simply use INSULATION to
keep your feet warm.
