This question has two parts. First, answer Part A. Then answer Part B.

Antonio 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?  __________

Part B
What is the variable in this experiment?  __________

5.6.D

Picking up a heavy box is much more difficult than putting it down. What is a likely explanation for this?

The action is less difficult because nothing is pulling the object toward the ground.

The force of gravity acts against you when you try to push something to the ground.

The force of gravity is pulling the box toward the ground which makes the action of putting the box down easier to do.

Pushing force is more difficult to accomplish than pulling force.

A student wants to experiment to determine how the height of a ball dropped in a box of sand will affect the crater size it will make in the sand.

What other piece of equipment will be most useful in conducting this experiment?

triple beam balance for mass

graduated cylinder for volume

stopwatch for time

meterstick for length

Students are performing the investigation shown below.

What are they most likely testing?

How the angle of the pulling force affects the amount of force needed to move an object

How friction affects the amount of force needed to move an object

How mass affects the amount of force needed to move an object

How acceleration affects the amount of force needed to move an object

Asad wants to know the maximum distance a toy car will travel when he gives it a strong push. Which experiment below best allows Asad to determine this?

An experiment that involves pushing the same toy car, with the same force, many times on the same surface

An experiment that involves pushing the same toy car, with a different force, many times on two different surfaces

An experiment that involves pushing two different toy cars, with a different force, five times on two different surfaces

Jason blows up a balloon, and holds the opening of the balloon closed with his fingers. He then lets his fingers slip, and the balloon flies away. Which experiment measures what happens to the balloon due to the air escaping from its opening?

An experiment that measures how small the balloon is before it is blown up

An experiment that measures how much the balloon weighs after the air escapes from it

An experiment that measures how long it takes him to blow up the balloon

An experiment that measures how quickly the balloon moves when air escapes from it

A teacher did a demonstration for her class. She found the mass of a baseball and a crumpled piece of paper. She then held both at a height of 1 meter above the table top. She dropped both at the same time. The students wrote about the demonstration, shown on the journal pages in the illustration below.

According to the above information, which student has written a testable hypothesis?

A trebuchet can launch an object a very far distance. When the rope is cut, the counter weight will be pulled towards the ground, causing the object on the other end of the trebuchet to launch.

A student designed an experiment to determine which type of ball would go the farthest using the trebuchet. The student used 3 types of balls and 3 counter weights, each with a different mass.

What should the student do to improve the experiment?

Use the same type of ball for each trial

Use the same counter weight for each trial

Use balls with different size but the same mass for each trial

Change the length of the rope for each trial

A student wanted to test the effect of friction on a toy car rolling down a ramp. She has constructed the ramp with five lanes, each covered with a textured material.

She rolled a toy cart down each lane and used a timing device to measure the length of time it took the cart to reach the end of the ramp. Her results are shown in the chart below.

Refer to the information above. What conclusion could the student make based on this experiment?

The force of friction is least on the tile.

The force of friction is least on the sandpaper.

The force of friction is not affected by material.

The force of friction is greatest on the wood.

Choose TWO correct answers.

Some students were investigating which surfaces would allow a ball to roll the farthest. Which of the following would be essential in their investigation?

Stopwatch, meter stick, calculator, soccer ball, 4½-foot–tall student

4-foot-tall student, 4 1/2-foot-tall student, 5-foot-tall student, soccer ball, meter stick

Grassy field, gym floor, concrete sidewalk, soccer ball, meter stick

Soccer ball, bowling ball, beach ball, stopwatch, meter stick

A student drew a maze on a piece of cardboard. He challenged another student to maneuver a paperclip successfully through the maze to the stack of papers by moving a magnet under the cardboard.

According to the information and image shown above, what force was the student demonstrating?

The resisting property of friction

The pulling force of gravity

The attractive force of magnetism

The insulating property of cardboard

The force of friction was less on the left so the box moved to the right.

What can be said about the effect of the force being applied by the student on the left?

The pushing force was greater on the left so the box moved to the right.

The force of magnetism was greater on the left so the box moved to the right.

The pull of gravity was greater on the right so the box moved to the right.

The force of friction was less on the left so the box moved to the right.

A group of students is investigating the effects of force on tooth enamel when brushing teeth. Tooth enamel is the thin, hard, clear outer covering of teeth that protects teeth from damage. The student's used hard-boiled eggs to represent teeth, the same toothbrush, the same brand of toothpaste, and the same amount of water. What safety equipment should the students wear in this investigation?

safety goggles

helmets

aprons

gloves
