Force, Energy, Experimental Design

A group of students conducted an experiment testing the effects of force on a toy car. They tested different materials to observe how far the toy car would travel on each material as it came off a ramp. The materials they tested were sandpaper, tile, notebook paper, and smooth foil. Which material would the toy car most likely travel the shortest distance on?

• Sand Paper

• Tile

• Notebook paper

• Smooth foil

All of the bulbs in the electrical circuit shown below are glowing. What will happen if the switch is open?

• The bulb closest to the switch will glow brighter

• The bulb closest to the switch will go out

• All of the bulbs will glow brighter

• All of the bulbs will go out.

Students are creating circuits using a D-Cell battery, copper wires, a switch and a light bulb. When the items are connected to the light bulb, it does not produce light. All of the following are reasons that the circuit would not produce light EXCEPT

• Th switch was open, causing an open circuit

• The wires are not connected properly

• Th light bulb is burned out

• The students created a closed circuit

The diagram shows a periscope to see the objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope?

• Contains mirrors that reflect the object

• Magnifies small objects so they can be seen

• Absorbs the light rays passing through it

• Separated the light into different colors.

Students often use a hand lens to make small objects appear larger. A hand lens makes objects appear larger because the lens-

• Increases the light's strength

• Changes the color of the light

• Bends the light passing through it

• Convers light energy to heat
