01 / UNDERSTAND

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.

Pause. Make the idea your own.

Explain one idea to a partner, draw it or write it in your own words. Which part is an observation, an example or a question?

You can use a home language. No need to share personal experiences or finish everything in one sitting.

02 / MAKE IT YOUR OWN

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.
