A radiometer is a device with fins that spin when light energy strikes them. A picture of a radiometer is shown below. As part of an experiment, a light source was placed 50 centimeters (cm) from a radiometer. The light source 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.

Which color of light provided the greatest amount of light energy according to the data in the table?

• red

• green

• blue

• white

Giovanny is comparing types of rocks. He writes as many descriptions as he can for five rock samples. A scientific method is a set of steps in many scientific investigations. The steps are not always the same, nor are they always done in the same order. Which of these steps in a scientific method best describes what Gio is doing?

• Form a conclusion

• Make observations

• Organize and communicate data

• Design and conduct an experiment

Hudson is performing an investigation using several earthworms. He places a rectangular box under a bright lamp and covers one-half of the box so that it is shaded. Then, he puts the earthworms into the box on the side that is still brightly lit. Later, Hudson notices that all of the earthworms have crawled over to the shaded side of the box. Based on his investigation, which of the following is an observation and NOT a personal opinion?

• Earthworms are afraid of light.

• Earthworms like staying together.

• Earthworms move away from light.

• Earthworms like living in the ground.
