You are going to enter a biology science fair. You and your friends have come up with some interesting ideas. Look at the questions below and choose all of the questions that are testable and would lead to a good science fair project.

A good science fair question can be investigated with observations or a controlled experiment and measurable results. For B, you could compare egg sizes from chickens fed peanuts with those from chickens not fed peanuts. For C, you could count cricket chirps and compare them with measured air temperatures. Whether the Abominable Snowman is afraid of rats cannot be reliably tested, and “more cuddly” is subjective, making D difficult to measure objectively.
