The Sun’s Energy

Read each slide.

Look closely at each picture.

Answer each question.

The sun gives us both heat

and light.

The sun’s heat makes Earth the perfect place to live.

The light from the sun will

heat up any surface it

hits.

When the sun’s rays are blocked we call it shade. Shade is always cooler

than sunlight.

We measure the sun’s

heat energy with a

thermometer.

This is a terrarium. The light bulb acts like the sun.

It provides heat and energy.

This is a terrarium for lizards.

A strong light acts like the sun.

This is an aquarium. The light acts like the sun.

It provides heat and energy for the plants and animals.

Aquariums and terrariums are like small models of our

Earth.

The sunlight for the aquarium warms the fish and makes

the plants grow.

The plants are eaten by the tiny fish.

The tiny fish will be eaten

by bigger fish.

Which will be eaten by even bigger fish.

The big fish will one day die and its body will nourish the plants which will grow and

feed the little fish which will feed the bigger fish and it goes round and round and

round.

The energy flows on and on.
