Today you will need:

Can you read in the dark?

Poll

Do you think it is possible to read in the dark?

Yes

Objects must reflect light to be seen.

How does light interact with different materials?

Write the question at the top of the next blank page in your INB. Then tape or glue one square of each medium. Using the given flashlight shine a light on each medium and note what you observe for each one.
