1. A student is investigating the speed they can skate over 3 different surfaces. They tested grass, concrete and tile.

Which type of force is the student investigating?

• Gravity

• Friction

• Magnetism

What is the variable being tested in the experiment?

• Distance the car traveled

• Height of the ramp

• Surface of the ramp

• Speed the car traveled

3)  In an investigation it is important that you only have one variable because if you change multiple things at once, you can’t tell what caused the results.

• True

• False

4) Why did the block on the sandpaper ramp come to a stop after it was pushed down the ramp?

• 1. The force of friction acted on the block and made it stop

• 1. The force of gravity acted on the block and made it stop.

• 1. The force of magnetism acted on the block and made it stop

Which question would the students be able to answer with the data?

• What is the physical force that makes a top spin?

• How does a top's mass affect how long it spins?

• What color top spins for the shortest amount of time?

• Why does a top stop spinning after one minute?

8) In order for an object to be attracted to a magnet it must be made of:

• Iron or steel

• Plastic

• Wood

• Glass

9) A student wants to test how fast a ball will drop from different heights. What would he need to do after each trial?

• 1. Test the ball from a greater height

• 1. Change the type of ball

• 1. Change the mass of the ball

10) Students tested how different surfaces affect how far a ball travels. What can be concluded from the results?

 Select 2 answers

• • The tile had the least amount of friction, so 

  the ball rolled the furthest.

• • The sand had the most amount of

  friction, so the ball traveled the furthest.

• • The ball traveled the greatest distance on

   the cement.

• • Cement caused more friction than grass.

• • Sand caused more friction than tile.

11) A boy is shown pushing a friend on the swing. Which direction did the swing move after he pushed it?

• 1. The swing moved in the same direction of the force.

• 1. The swing moved in the opposite direction of  the force.

• 1. The force did not make the swing move
