A Fun Science Activity Simulating The Phases Of The Moon

The moon circles around the earth and the journey takes about a month. The moon does not have any light of its own and we only see the moon because of light from the sun reflecting from it. As the moon circles the earth the sunlight illuminates different parts of the moon. This is why the moon seems to take on different shapes or "Phases" during the month. When it is full moon the moon is completely lit up and it happens only once a month.

What we are going to do is simulate it and see why it happens.

This is what you'll need:

*A football (soccer ball) or beach ball
*Glue
*Glue Brush
*A glass
*Silver paper or foil
*A pair of scissors
*Reusable adhesive
*A torch
*A friend to do this project with

This is what you need to do:

1. Do this project in a room that can be darkened.
2. Wash and dry the ball thoroughly.
3. Now you have to paint glue all over the ball.
4. Rest it on a small bowl to keep it still.
5. Now you have to cut silver paper or foil into large square sheets.
6. Whilst trying to keep the paper as smooth as possible, wrap up the ball in the paper.
7. This now represents your moon.
8. Place a small piece of reusable adhesive under the ball (your moon.)
9. Place your moon on a table, with the adhesive keeping it in place and preventing it from rolling of the table.
10. Now is where the friend comes into the picture.
11. Let your friend stand at the one end of the table and shine the torch with a strong beam on your moon.
12. Now you have to go and stand at the opposite side of the table.
13. With the main lights out, look at your moon.
14. Now you have to gradually move around the table whilst still looking at your moon.
15. The moon is still being lit up on the one side by the torch.
16. You will see the different shapes it takes.
17. These shapes represent the different phases of the moon.
18. Can you name the phases?
19. Try to illustrate the phases for your project.

In this project your "moon" kept still and you moved around it. This was only to let you see the effect. In real life, of course, the moon circles around the earth whilst the earth circles around the sun. Try and explain why that has the same effect on the appearance of the moon as your circling your "moon."
