Use this worksheet to design your controlled experiment that you will use to test your hypothesis.

• A good science project tests a hypothesis with an experiment.

• A well designed experiment should clearly define all the variables of the experiment (independent variable, dependent variable, control, and constants).

• To reduce bias, a good experiment should utilize a numerical measurement to answer the problem.

• To increase accuracy, a good experiment should utilize a device or tool to make accurate measurements.

• To increase reliability, a good experiment should have multiple trials.

• To make data clear, a good experiment should use units.
