Can you catch a shadow?
A wall, your hand and a little light. Let the investigation begin.
Take your time. Speak, draw or write your answers.
Here is what is happening.
A shadow forms when an object blocks light. An opaque object blocks most light; a clear sheet lets much of it through. Changing the positions of the light, object and wall can change the shadow.
Your little investigation
What you need
A torch, a wall and your hand. Ask an adult to help; keep the beam away from eyes.
Shine the torch at a wall. Put your hand between them.
Keep the torch and wall fixed. Move your hand closer to the torch, then farther away.
Describe or draw what changed. Predict what a spoon would do.
