Question and Hypothesis Worksheet

A student is interested in designing several experiments to test the factors that effect how quickly an

Alka-Seltzer® tablet dissolves in water (solution rate). For each question, write an appropriate

hypothesis that could be tested with an experiment. Be sure each hypothesis is in the proper “If…,

then… , because…” format.

Example:

Question: What effect does stirring have on solution rate?

Hypothesis: If the water is stirred, then the tablet will dissolve faster because stirring increases solution

rate.
