A steel ball is at one end of a box that is moving forward as shown. The box suddenly stops. According to Newton’s first law, what happens to the steel ball just after the box stops?

• Because of friction, the ball continues rolling forward at the same speed.

• Because of friction, the ball rolls forward at an increased speed.

• Because of inertia, the ball continues rolling forward at the same speed.

• Because of inertia, the ball rolls forward at an increased speed.

Students mixed two liquids in a beaker and listed their observations. Based on these observations, which statement contains the best evidence that a chemical reaction occurred?

• There is a change in shape.

• There is a change in volume.

• The two liquids mix into a solution.

• The two liquids form a new substance.

A farmer digs a small pond in a pasture. The farmer adds young individuals from two species of algae-eating fish to the pond and plants some reeds around the edges of the pond. The farmer wants the pond to be a sustainable ecosystem. Which of the following would be most helpful in increasing the pond ecosystem’s sustainability?

• Decreasing the number of plant species around the edges of the pond

• Introducing older fish of the same species into the population of algae-eating fish

• Having a greater diversity of living organisms in the pond

• Adding gravel between the water and where the reeds are planted

Students view two different cells under a microscope. They record their observations in the table shown. Based on the organelles observed, the students determine that cell 2 is a plant cell because it has an organelle that —

• allows water to enter and exit the cell

• contains genetic information

• stores water and nutrients

• produces its own food

Roller coasters are popular attractions at amusement parks. A cart on a roller coaster approaches the highest point on the coaster. As the cart reaches the top, it slows down. Which statement best describes the energy of the roller coaster as it slows down while traveling to the top of the coaster?

• The cart gains both kinetic and potential energy.

• The cart gains kinetic energy and loses potential energy.

• The cart loses kinetic energy and gains potential energy.
