Description:
On Earth, the sun is our main and most important
source of heat. The heat from the sun warms our whole planet and all of the
living and non-living things on it. If there was no heat from the sun, there
would be no life on Earth.

Heat is a form of energy that makes things feel warm.
What things make us feel warm?
Where does the heat come from?
Something that produces heat is called a source of
heat.
On Earth, the sun is our main and most important
source of heat.
The heat from the sun warms our whole planet and all
of the living things on it.
Did you know if there was no heat from the sun, there
would probably be no life on Earth?
The heat from the sun warms non-living things too; it
warms rocks, soil, and the water in our rivers, lakes, and the ocean.
Burning wood, gas, and oil are sources of heat.
When fuel burns, they produce heat.
They also produce light.
Many appliances and devices in our homes are sources
of heat too.
Ovens, kettles, and toasters are sources of heat.
Clothes dryers, irons, and hair dryers are sources of heat too.
I hope this video warms your
day! See you next time.
