John Cena wanted to find how fast soap melts in different temperatures of water. Write a hypothesis for this experiment.
Example: I hypothesize that the warmer the water, the faster the soap will dissolve.

John Cena was doing a experiment on how fast people of different ages could run. Write a hypothesis!
Answers vary. Example: I hypothesis that the older people will run slower, and the people in the middle of their lives will run faster, and the younger people will run a little slower.
