Leo wants to make some shade on a sunny day.
What materials should he use?
Help him find out.

What materials are items in our classroom made from?

What happens to a light beam when it strikes these materials?
Does it pass through?

How could you test some materials to find a shade for Leo to use?

Choose some items to test.
What do you think will happen with each one?

Build a light source to help Leo test the materials.
Work together.
Plan a way to test how much light comes through.

Program your model so the light turns on.

Now work alone. Test the materials.
Put each type of material in front of the light beam.
How much light gets through?

Group the materials.
Use the words “all light”, “some light”, or “no light.”

Use your model and explain:
What items did you test?
What materials are they made of?

Which materials let all the light through?
Some light? No light?

Which would work best to create shade on a sunny day? Why?

Build a model of a sandpit.
Make a frame to hold a shade.

Test the materials you think will work best as shades.
What kind work best?

Great job!
