□ do different liquids freeze at the same rate?
□ do cookies taste better when they are baked in a gas oven or in an electric oven?
□ does temperature affect the strength of a magnet?
□ does the color of water affect how quickly it evaporates?

Explanation:

A testable hypothesis requires measurable variables and objective verification. "Better" (A) and "taste better" (C) are subjective. The others have quantifiable/observable variables: freezing rate (B), magnet strength (D), evaporation rate (E).

Answer:

B. Do different liquids freeze at the same rate?
D. Does temperature affect the strength of a magnet?
E. Does the color of water affect how quickly it evaporates?
