Your draft hypothesis statement should include the following:
- the question or problem you are trying to answer;
- how the independent variable will be changed;
- the measurable or testable effect it will have on the dependent variable;
- and your best guess as to what you think the outcome will be.
Use the space on the Experiment Design Worksheet to draft your hypothesis statement.
Tip: A hypothesis problem can be stated in different ways. Here are some examples:
As a question: Does temperature affect the rate of plant growth?
As a statement: Temperature may affect the rate of plant growth.
As an if/then statement: If temperature is related to the rate of plant growth, then changing the temperature will change the rate of plant growth.
