Multiple Choice

Erika has found a prism in her dad’s office. She takes it outside to play. As she does, sunlight hits the prism. Explain what happens as the sunlight passes through the prism.

• The sunlight bends as soon as it goes through the prism since it is a different media.

• The sunlight is bounced back from the prism back to Erica’s hand since the prism is reflective.

Multiple Choice

Eli did an experiment. He looked at some colored wooden blocks in three different places and he recorded his observations. First, he looked at the blocks in sunlight. The blocks had bright colors. Then he looked at the same blocks under a lamp in a dark room. The blocks still had bright colors. Next, he placed the blocks in a cardboard box that had a small hole that he could look through. Eli recorded that he could not see any of the blocks inside the box. Why could Eli not see the blocks inside the box?

• The cardboard of the box absorbed all of the light that the blocks made so none could go through the hole.

• The hole in the box was too small for light from the blocks to pass through.

• The cardboard of the box absorbed all of the outside light so the blocks could not reflect light to his eye.

• The box reflected darkness to his eye that was stronger than the light.
