Answer:
The questions that are testable and would lead to a good science fair projects are: Does feeding peanuts to chickens make their eggs larger?, Do the chirps of a cricket indicate air temperature? and Why are small dogs more cuddly than large dogs?
Step-by-step explanation:
These three questions can be tested, for all of them the animals or insects are needed as well as a group of people for the third question that can tell us their experience cuddling small and big dogs. The question - Is the Abominable Snowman afraid of rats?- is not appropriate for a science fair due to the fact that the existence of the Abominable Snowman is not proved and he would be needed for the experiment.
