2. 2. Students want to explore how light interacts with different materials. Which of the following investigations would BEST allow students to see how light interacts with different types of materials to classify them.

• Take three different types of flashlights to see the amount of light that shines through a piece of construction paper.

• Take three different types of flashlights to see the brightness of light when turned on in a dark classroom.

• Take three different types of materials such as: cardboard, wood, and a thick blanket to see the amount of light that shines through it when placed under a flashlight.

• Take three different types of materials such as: aluminum foil, plastic wrap, and white paper to see the amount of light that shines through it when placed under a flashlight.

5.  A student held a smooth piece of aluminum foil near his face and could see himself. Then, the student crumpled up the foil, opened it back up, and looked at the foil again. He could not see himself this time. Why was he unable to see himself in the crumpled piece of foil?

• The foil lost its thickness, and light was able to travel through it.

• The foil was uneven and trapped all of the light that traveled toward it.

• The foil was uneven, and the light that hit it traveled in many different directions.

• The foil absorbed the oils in Joshua's hand, and the oil caused light to stop at the foi

6. A student is planning an investigation to determine why we can see our reflection in some materials and not others. Which of the following investigations can the student perform to see the difference?

• The student should look in mirrors at different angles.

• The student should compare different types of mirrors.

• The student should look at the same piece of glass during the night and day time.

• The student should look into different substances with smooth and rough surfaces.

8. A card with writing on it is viewed through a jar with water in it. Part of the writing on the card appears to be changed. The change in the appearance of the writing is the result of which of the following?

9. 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.

• The sunlight continues to go in a straight line through the prism since light travels in straight lines.

• The sunlight stops traveling the moment it reaches the prism since different media make the sunlight stop moving.
