Andrew walks through his garden and observes that the shapes of dewdrops are not always the same. Suppose he wants to investigate using the scientific method. Which questions are testable questions that he can ask to look into the reasons for the different shapes? Does the shape of the dewdrop depend on the temperature of the surface?
Which dewdrop seems to have the most unusual shape?
Is the material of the surface responsible for the shape of the dewdrop?
Which shape of dewdrop is the most pleasing to the observer?
Does the shape of the dewdrop depend on the moisture in the atmosphere?

A, D, and E are testable questions. Each question is not opinion based like B and D. Each one of these questions (A,C,E) can be proven by facts and cannot be determined by an opinion.

I hope this helps!
