Light from sun reflects off object and we see the color that is reflected.

Review

When white light hits an object, all the colors are absorbed except for the color of that object.

Example:

Blue – All colors absorbed except blue, which is reflected to eye.

White – No colors are absorbed.

All colors are reflected to eye. (white light)

Black – All colors are absorbed.

No colors are reflected to eye.

Activity Instructions

For this activity, you will be given a colored balloon. You will see objects of various colors on the screen.

If the color you have is absorbed by the object, you need to cover the balloon with your body. DON’T POP IT!!

If the color you have is reflected by the object, you need to reflect the balloon into the air above you.
