Christmas Shadow Puppets

Shadows are formed when light cannot pass through an object. As light moves in a straight line, shadows are the same shape as the object making the shadow.

To demonstrate this you can make shadow puppets. We made a Christmas tree puppet and some different shapes to put on the top.

What you need

• card
• scissors
• straws or lolly sticks
• tape
• torch or light
• Pens
• Glitter and sparkles

What to do:

1. Draw a tree shape onto some cardboard, and cut it out.
2. Attach the tree to a lollypop stick or straw.
3. Decorate if you wish.
4. In a dark room hold the shadow puppet against a wall and shine the torch or a light at them.
5. You should see the shadow on the wall.

Try moving the puppet further from the wall to make the shadow bigger.

A Real Life Example

Shadows are formed during an eclipse of the sun. An eclipse is when the moon passes between the sun and the Earth, casting a shadow over Earth. If the shadow blocks out all the light from the sun, it becomes dark during the day.
