Shadow Fun

Anders Sandberg

This experiment is done in a dark room to teach a child about shadows.

Materials Needed:

• Torch / Lamp
• Cardboard / Thick Paper
• Scissors
• Wall (preferably plain)

What to do:

• Cut a creative shape out of cardboard.
• Shine a torch or lamp on the card.
• Hold it in front of you, with the wall behind you.

The Science Factor:

The holes in the cardboard let the light of the torch / lamp through but the card itself blocks the light. You get a shadow on the wall in the shape of the card. A shadow is made because light cannot get through the cardboard.

Hints and Tips:

• Watch what happens when you move the shape closer and further from the lamp.
• Use your hands to create different shadows on the wall.
