Sunshine

Sunshine produces not only light, but also warmth on our earth.
Without sunlight, there could be no life on Earth, because humans, animals and plants need sunlight to grow and be happy.

Plants, animals and human beings need sunlight

Plants use sunlight to grow and to produce the green color in their stems and leaves. A plant without enough sunlight will look very pale after a while.
Sunlight makes the human body produce Vitmain D, and Vitamin D is very important to be healthy and feel happy. People who don't get enought sunlight, because they are ill or can't go outside for other reasons, sometimes tend to be a little sad.

Sunlight can do harm

Sunlight consists of different kinds of light, and some parts of it is not good for us. The different layers of air around the earth filter the sunlight so that not too much of the bad light comes through. But part of this filtering layer, the ozon layer, becomes thinner every year and we have to take more and more care to protect us.
Being in sunlight too much can cause sunburn and it can hurt your eyes. This is why you should always sun protection such as sun lotion, sunglasses and hats to cover your head. It is better to wear light colours in the sun because they reflect the sunlight and you don't get too warm. Dark colours absorb the sunlight and produce even more heat.

Catch the sunlight and produce heat!

You can catch the sunlight and see that it gets absorbed more by darker colours.
Take two tin cans which have to have the exact same size.
Wrap a piece of black paper around one of the cans and a white peace of paper around the other. You can hold the paper in place with sticky tape. Fill both cans with the same amount of water and place them in the direct sunlight. Leave them there for 2 hours. After 2 hours, take a thermometer and take the temperature first of the can with the white paper and afterwards of the can with the black paper. The water in the black can will be hotter than the water in the white can.
This is because the white paper reflects most of the sunlight while the black paper absorbs most of it. When light gets absorbed, it turns into heat.
