Select the correct hypothesis for the following variables.

Research Question: Does salt water freeze faster than fresh water?

Independent Variable: type of water (salt water or fresh water)

Dependent Variable: time it takes water to freeze

• If salt water freezes faster than fresh water, then I will test salt water and fresh water.

• If I test salt water and fresh water, then salt water will freeze faster.

• If I test salt water and it freezes, then I will test fresh water.
