Worksheet Overview

QUESTION 1 of 10

The sun is a huge glowing sphere of hot gas.

 

 

It shines down on earth, on all of us, the animals and plants and the land.

We need the sun to help everything grow and be healthy, BUT we also need to protect ourselves from the sun, as it can be dangerous if we get too much.

 

In this worksheet, you are going to think about the dangers of the sun and the best way we can protect ourselves and the Earth.

First, let's think about ourselves.

Which parts of our bodies might need protection from the sun?

Why do we need to protect ourselves from the sun?

How can we protect our eyes from the sun?

Why are the first pair of sunglasses best in helping us see in the sunshine?

How can we protect our bodies from the sun?

Explain your answer.

What has happened to this plant?

Some animals need protection in the sun, because like humans and plants, they can become too hot and dehydrated. Dehydrated means that something does not have enough water inside it to stay healthy and well.

 

 

This dog is panting to help cool it down as, unlike us, it cannot sweat to cool down.

Lizards are cool-blooded which means they cannot control their body temperature; they have to keep out of the sun to protect themselves from becoming too hot. 

 

Why do some animals need protection in the sun?

Look at this diagram:

 

 

The Earth also has to protect itself from the sun's strongest rays. 

How does it do this?

Use this information to answer questions 9 and 10.

The ozone is an important layer within the part of the atmosphere called the stratosphere. 

 

 

It is very important in helping protect us and the Earth from the sun's ultraviolet rays. These rays are so bright and hot that they would dry up all the water on Earth. Without water all living things on Earth would die. The ozone layer also helps keep important gases, such as oxygen, within the Earth's atmosphere. Unfortunately, scientists have discovered that the ozone layer has become much thinner and often develops holes in certain areas. They think this is likely to be caused by particular chemicals that people use called CFCs (Chloro-Fluoro-Carbons). In the past these chemicals have been used in aerosol cans, fridges, fire extinguishers and air-conditioning machines. However, many countries have pledged to stop using CFCs in new products.

 

Why is the ozone layer so important?

Why should we stop using CFCs?

Explain your answer.
