Students have short and tall ramps, and toy cars with which to 

perform an investigation.

Which of the following is a testable question they could answer in an 

investigation using these materials?

• Which material should engineers 

  use for high traffic roads?

• Does the mass of the toy car affect 

  the speed at which it rolls down the ramp?

• Does the height of the ramp effect 

  the distance the toy car will travel?

• Will the length of the toy car affect the 

  distance it will  travel?

Which of the following describes the best way to test the strength of 

several different magnets?

• Place each magnet in water to observe 

  if it sinks or floats.

• Count the number of paperclips each 

  magnet picks up.

• Use a triple beam balance to mass 

  each magnet.

• Measure the length and width of each 

  magnet with a meter stick

Antoina wanted to see how far she could slide a hockey puck 

across different surfaces. She chose to slide the puck across a sidewalk, 

an asphalt road, and the tiled kitchen floor in her house.

Antonia designed this experiment to observe which of the following forces?

• gravity

• friction

• magnetism

• electricity

Students conducted an investigation in which they rolled marbles 

across different surfaces to measure the effect of the force of 

friction on each surface. Friction slows down and stops objects.

Which of the surfaces tested showed the greatest amount of friction?

• Surface A

• Surface B

• Surface C

• Surface D

A student sets up an experiment using the ramp below to test how

friction would affect how far a car would travel after leaving a ramp.

In order for the student to test the effect of friction on a rolling car, which of the following variables would need to be changed?

• the height of the ramp

• the color of the car

• the mass of the car

• the type of surface on which the car rolls
