Jude investigated how long it takes different materials to slide down a ramp. He used three wooden blocks. He wrapped sandpaper around one block. He wrapped the second block in waxed paper. He did not wrap any material around the third block. In the table, Jude recorded the amount of time it took each block to slide down the ramp.

What question can Jude answer with this investigation?

• How many trials are needed to investigate how fast materials slide?

• How is friction different with different materials?

• Is a table good for sliding objects?

• What time is lunch?

Sheila is investigating the concept of gravity. She dropped a flat sheet of paper and a sheet of paper crumpled into a ball from the same height. She repeated the procedure from various heights. For every trial, the paper ball hit the floor in less time than the flat sheet of paper. Why did the paper ball always fall faster?

• Gravity is stronger for the paper ball.

• Air can get trapped in the paper ball.

• There is no friction for a ball-shaped object.

• The flat sheet was affected more by friction.

All magnets have sides that are opposite poles, called a north pole and a south pole. Look at the picture of four different magnets. The north poles are labeled N and the south poles are labeled S.

What does the picture show about magnetism?

• Magnetism is a contact force, and magnets can either attract or repel each other.

• Magnetism is a non-contact force, and magnets can either attract or repel each other.

• Magnetism is a contact force, and magnets can be pushed together and pulled apart.

• Magnetism is a non-contact force, and magnets can be pushed together and pulled apart.

Why do the bird’s wings move down when it flies?

• The wings need to go down some of the time to reduce friction.

• The wings need to point in the direction of the force of gravity.

• The wings move from up to down to avoid the friction between the air and the wings.

• The wings push down on the air to overcome gravity.
