Question

Doyle learned that only one side of the Moon is ever visible from Earth. He wants to investigate how the moon moves around the Earth and to understand how this motion causes the phases of the moon. Which kind of scientific investigation should he use? development of a model a review of existing work a field study

Answer 1

Answer: Create a model.

Explanation: He should develop a model of the Earth-Moon-Sun system. This will let him clearly see how the Moon must move in order for one of its sides to always face away from the Earth. If he uses a light source for the Sun in his model, it will also show how the phases of the Moon happen. The real Earth-Moon-Sun system is too large for him to observe it in the same way.
