A radiometer is a device with fins that spin when light energy strikes them. A picture of a radiometer is shown at the left. As part of an experiment, a light source was placed 50 centimeters (cm) from a radiometer. The light sources gave off four different-colored lights for 30 seconds (s) each. After each color of light was turned off, the amount of time the fins on the radiometer spun was recorded. The results are shown in the table below. Which color of light provides the greatest amount of light energy according to data in the table?

• red

• blue

• green

• white

A student designs a toy boat by using a sponge for the body of the boat and a piece of cloth tied to a pencil for the sail and mast. He then places the boat in a container filled with water. The boat stays afloat for about 30 minutes before sinking. Which of these possible solutions will most likely improve the results of this experiment by increasing the time that the boat stays afloat in the water?

• change the shape of the sponge

• change the amount of water in the container

• change the material used to make the body of the boat

• change the size of the cloth used for the sail of the boat
