What is heat?

Heat is thermal energy that flows between

objects due to a difference in temperature.

Lesson 1 a

How does heat travel?

conduction convection radiation

Lesson 1 b

What is thermal conductivity?

Thermal conductivity is the ability

of a material to transfer heat.

Lesson 1 c

When is heat waste?

Cars will stop working if they cannot release their extra heat.

Lesson 1 d

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?

Lesson 1 Vocab Review b

An infrared image of a house

shows that the roof is brighter

than the rest of the house. What

does this mean?

The roof is

radiating

more heat

energy.

Convection currents

inside keep bringing hot

air to the roof; the roof

Finding objects by using sound

waves is known as echolocation.

Lesson 2 e

How could a stereo playing loudly rattle

dishes?

Main Idea

The vibrations from the speakers could travel

as sound waves through the air and hit the

dishes. The sound energy from the wave

could then vibrate the dishes.
