Question 2 - 30 • Bo learns about the law of inertia. It states that objects at rest tend to stay at rest, and objects in motion tend to stay in motion. The state of motion changes only when another force acts on an object. Bo wants to use this law to predict how a soccer ball will roll on the grass after he kicks it. Which statement best describes the motion of the ball? • A. The ball will keep rolling until the forces between the ball and the grass makes it stop. • B. The ball will not move because it is at rest when he kicks it. • C. The ball will have little movement after he kicks it because it wants to stay at rest. • D. The ball will keep rolling forever after he kicks it.

Answer 2 – 30 • A. The ball will keep rolling until the forces between the ball and the grass makes it stop.

Results are not reviewed by peers. • C. Results are based on a small sample size. • D. Results are based on an undisclosed process or procedure.

Answer 3 – 10 • A. Results can be reproduced.

Question 3 - 20 • Hillary is dropping objects that are the same volume. She wants to investigate how an object’s mass affects the average speed at which it travels when dropped, until it hits the ground. Which variable must Hillary change during the experiment? • A. the timer • B. the drop height • C. the mass of the object • D. the place where she drops it

Answer 3 – 20 • C. the mass of the object

Question 3 - 30 • Mackenzie investigates how the volume of gas inside a balloon changes as the temperature of the gas changes. She takes an inflated, sealed balloon from a freezer and uses a string and a meterstick to measure the balloon’s circumference. She moves it to a sunny window for 15 minutes. Then, she measures the circumference with a tape measure. She records these measurements in a data table. Mackenzie realizes that she made a mistake in her experimental procedure. What was wrong with her procedure? • A. Data should not be recorded directly into a data table. • B. She measured circumference using two methods. • C. She conducts the experiment by herself. • D. She changed the amount of gas in the balloon.
