What is the Hypothesis?

• If children were exposed to fuzzy bunnies and at the same time a loud cymbal was struck close behind them, then that child would be afraid of all fuzzy things.

• If children were exposed to fuzzy bunnies, they would become more friendly.

• If children heard a loud cymbal, they would become interested in music.

• If children saw fuzzy bunnies, they would want to have one as a pet.

What is the Independent Variable?

• Exposure to loud cymbal noise when children are with fuzzy bunnies.

• The reaction of children to the bunnies.

• The number of children in the experiment.

• The color of the bunnies.

What is the Dependent Variable?

• Whether or not the children developed a fear of fuzzy things.

• The age of the children in the study.

• The type of fuzzy things used in the experiment.
