Franz wants to investigate moon craters. He drips water into a shallow pan of flour. He holds the dropper at a different height each time he moves to a new area of the pan. Franz observes that the water drops make dents of differing sizes in the flour. What claim does this evidence support?
The flour is not very strong.
The water is too heavy for his test.
The flour will dent when the water drops on it.
The flour will not dent if he drops water on it.

Adessa observes that a sunflower plant changes its position throughout a day. Adessa wonders what causes the plant to change its position throughout the day. She wants to plan an experiment to find an answer. Why should Adessa research her question before experimenting?
to make it easier to share results
to decide whether the scientific method should be used
to reduce the number of steps needed for the experiment
to find information to help set up her experiment
What is "evidence?"
communicating results
data that support or reject a hypothesis
an educated guess
statement about what will happen in an experiment
