Front

The toy car and ramp seen above might be used to answer which testable question?

Back

What effect does gravity have on a toy car?

Front

By changing the surface over which the car rolls from sandpaper to wax paper, you might be able to test the effect of what force?

Back

Friction

Front

Which two tools would be most useful in testing how the mass of an object can affect the distance it moves with a push?

Back

Balance and meter stick

Front

How might you test the strength of several different types of magnets?

Back

Measure the attraction force of each magnet

Front

What variable is likely to lessen the force required to push a square cardboard box from one side of the room to the other side? Options: Adding several heavy weights to the box, Tipping the box onto its side, Adding another box on top, Placing the box onto a wheeled cart.

Back

Placing the box onto a wheeled cart.

Front

Some students were investigating if the height that a ball was dropped would affect its bounce. The ball was dropped at 60 cm and at 80 cm. What statement is true of the results for each of the heights that the balls were dropped? Options: There was no difference in the results. The ball dropped from 60 cm bounced 20 cm higher than the ball dropped from 80 cm. The ball dropped from 80 cm bounced higher than the ball dropped from 60 cm. The ball dropped from 60 cm bounced higher than the ball dropped from 80 cm.

Back

The ball dropped from 80 cm bounced higher than the ball dropped from 60 cm.

Front

A ball is sitting loose in a moving wagon. If the wagon stops suddenly, what will happen to the ball?

Back

Roll forward in the wagon and fall off.

Front

During an experiment, students applied an equal force to push each box. If they pushed all of the boxes on the same surface for the same amount of time, which box will MOST LIKELY move the greatest distance? Options: 30 kg, 15 kg, 150 kg, 40 kg.

Back

15 kg

Front

What question were the students most likely trying to answer when rolling a full water bottle down both ramps?

Back

How does ramp height affect the distance a full water bottle will roll?

Front

What is the variable (change) in the investigation where a student measures the distance a ball can be pushed by air from a small fan? Options: The mass of the balls being pushed by air, The length of the surface on which the balls roll, The amount of wind pushing the balls, The type of surface the balls are rolling on.

Back

The mass of the balls being pushed by air.
