2021 UTSW STARS Biology Camp Experimental Design

The type of variable that responds to the experiment and is what you measure to determine if your hypothesis is true.

• Independent

• Dependent

• Control

• Constant

The type of variable that you change or manipulate in an experiment.  It is what you are testing.

• Independent
• Dependent
• Control

The parts of the experiment that must be kept the same.

• Constants
• independent
• Dependent

The purpose of the control group is:

• To use for comparison with experimental groups.

• To maintain a constant environment for all variables.

• To establish a normal environment.

• Adhere to universal scientific principles.

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

Should experiments be repeated over and over to see if the results are the same each time?

• yes
• no

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
