Anthony designs an experiment in class that includes a golf ball, a meter stick, and a tray of flour with a level surface. He drops the ball from a different heights of 0.5 m, 1.0 m, and 1.5 m, measures the depth of the crater left behind, and levels the surface between each drop.

Part A: What question is Anthony trying to answer with this experiment?

• Will the mass of the golf ball affect the size of the crater?

• Will the golf ball make a crater when it drops in the flour?

• Will the height from which the golf ball is dropped increase the size of the crater?

• Will the type of flour affect the depth of the craters made by the golf ball?

Two researchers conducted an investigation. They walked and then ran along a 30-meter-long track in the rain. The table shows the amount of rainwater their clothing collected. Which conclusion is BEST supported by these data?

• Walking dries clothes faster than when running in them.

• Running makes clothes hold more water than when walking through rain.

• Clothes come into contact with less water when a person is running through the rain.

• Clothes take less time to get soaked with water when a person is walking.

Look at the set of lights in the picture. A: What will happen if one bulb burns out in the circuit?

• All the lights will stop working.

• The other lights will still work.

• Only the first light will work.

• Only the last light will work.

Look at the set of lights in the picture. B: Which statement best supports the answer in Part A?

• In a series circuit, one burned-out light bulb will prevent all the light bulbs from lighting.

• In a series circuit, one burned-out light bulb will have no effect on all the other light bulbs.

• In a parallel circuit, one burned-out light bulb will prevent all the light bulbs from lighting.

• In a parallel circuit, one burned-out light bulb will have no effect on all the other light bulbs.

This question has two parts. A: A group of students created a hovercraft model out of materials found at home. They used a dish soap bottle top, a CD, and a balloon. If the students blow up the balloon, what can they expect to see happen?

• The hovercraft will lift off of the table.

• The hovercraft will slide to the right.

• The hovercraft will slide to the left.

• The hovercraft will not move.

B: Select the best explanation of your answer in Part A.

• The push force from the air in the balloon does work on the table to change the shape of the hovercraft.

• The push force from the air in the balloon does work on the hovercraft to change the movement of the hovercraft.

• The pull force from the air in the balloon does work on the table to change the movement of the hovercraft.

• The pull force from the air in the balloon does work on the hovercraft to change its shape.
