10 Days to STAAR: Day 5

1. A person who is spearfishing is having difficulty. The fish appears to be higher in the water than where it is actually located. Which statement explains why this occurs?

• As light travels from air into water, it reflects to bounce back at an angle.
• The light is absorbed into the water, making the fish hard to see.
• As light travels from air into water, it refracts to change speed and direction.
• The light's energy causes the fish to move in the water.

3. A student is on a swing. How do forces affect their position and motion?

• Gravity causes the student's speed to increase from Position C to Position B.
• Gravity causes the student's speed to increase from Position B to Position A.
• The force from the student's legs moving causes the student's speed to increase from Position B to Position C.
• The force of the student pulling on the swing causes the motion to stop quickly.

4. Most gasoline-powered vehicles must replenish their gasoline at pumps. The gasoline there is created by refining crude oil from underground. Some people have converted their vehicles to run using biodiesel. It is a fuel made from vegetable oil or animal fats. How can these fuel sources be classified?

• Gasoline is made of nonrenewable resources, but biodiesel is made from renewable resources.
• Gasoline is made of renewable resources, but biodiesel is made from nonrenewable resources.
• Gasoline and biodiesel are both made of nonrenewable resources.
• Gasoline and biodiesel are both made of renewable resources.

5. A cold glass of water was brought outside on a warm day. After a few minutes, the glass appeared to be sweating. Droplets of water formed on the glass and ran down the sides. What has occurred?

• The water has begun to evaporate and change to a gas because it was heated.
• Water vapor in the warm air cooled and condensed to form water droplets as it interacted with the cold glass.
• The liquid water in the glass began to melt as it was brought into a warmer environment.
• The solid glass began to change its physical state when cold and warm temperatures interacted.
