Reporting Category Two Science

A student makes a model of the sun-Earth system by swinging a ball around her head. Using this model, the student is trying to explain how Earth stays on a path around the sun.The student explains that this path is the result of —

• The magnetic attraction between Earth and the sun

• Potential energy stored in Earth that originated in the sun

• The gravitational attraction between the sun and Earth

• Electromagnetic energy from the sun pulling on Earth

Why do you need to report your results to the scientific community?

• You don't need to ever report anything. Just keep all of your findings to yourself.

• You should report your results so others can replicate your experiment and fact check it; for validity.

• Everybody is in your business anyways, so you might as well share it with them before you hear a different version from someone else.

• You report your results to get famous.

A student models moon phases. She holds a foam ball on a stick in front of her body and then stands in front of a light as shown. The student uses herself to represent Earth. She turns her body slowly to represent four different moon phases. Which numbered diagram represents the student modeling a full moon?

• Diagram 1

• Diagram 2

• Diagram 3

• Diagram 4
