This picture is from Friction Lab 3. What was the independent variable?

• The wax paper

• The surface area on different sides of the wooden block

• The force (Newtons)

• The spring scale

This picture is from Friction Lab 1. What was the dependent variable?

• The spring scale

• The surface area on the different sides of the wooden block

• The wax paper

• The force (Newtons)

Look at the bar graph from Friction Lab 2, where we added more wooden block to the sandpaper. What does the data tell you?

• As we added more wooden blocks, the force (Newtons) stayed the same

• As we added more wooden blocks, the force (Newtons) decreased

• As we added more wooden blocks, the force (Newtons) increased

Look at the bar graph from Friction Lab 1, where we tested different surfaces with the same wooden block. What do you notice about the different surfaces?

• It required the same force (Newtons) to pull the wooden block across all the surfaces

• The rough surfaces required less force (Newtons) to pull the wooden block

• The rough surfaces required more force (Newtons) to pull the wooden block

What was one thing that stayed constant (the same) in all three friction labs?

• The surface

• The number of wooden blocks

• A spring scale

Look at the bar graph from Friction Lab 3, where we used wax paper and changed the surface area by dragging the narrow side and the bottom side. What does the data tell you?

• The force (Newtons) was significantly different depending on the surface area dragged

• The force (Newtons) was about the same depending on the surface area dragged
