Main Idea
Heat must flow into a candle in order
for it to melt. If heat is flowing into the
candle, it must be cooler than the steel
block.
A candle is placed on a steel block and begins
to melt. How do you know whether the candle
or the steel block is hotter?

Why will a comb rubbed with wool pick
up bits of paper?
Main Idea
Electrons from the wool build up on
the comb (static electricity). The comb
picks up paper by attracting the
protons in the paper.
