Globe around the Sun Category: Geography
Dated: 2009-11-10
In many parts of the world, the climate changes regularly throughout the year. These changes — spring; summer, autumn and winter — are called seasons. They happen because of the way the Earth is tilted on its axis — an imaginary line between the North and South Poles. As the Earth slowly circles the Sun once every year, different parts of the Earth are closer to the Sun. This affects the amount of light and heat they receive.Make a model to see how the seasons work. 

Steps to be taken

1. Cut the straw in half. Glue one half to the top of the ball and the other to the bottom. This is the Earth’s axis.

2. Ask an adult to take the shade off a table lamp and switch on the lamp for you.

3. Walk slowly round the lamp, tilting your ‘Earth’ at a angle and keeping it turned towards the Sun. See how the lamp lights up your Earth.

4. The earth also spins on it’s axis once every 24 ours, giving us night and day. Try to turn your globe round and round at the same time to see how this works.
