Why do we want to test only one independent variable at a time?

• Because it is hard to setup a data table with more than one variable
• To better identify what is causing the changes
• It is what has always been done
• It's easier to perform the experiment

Which describes the dependent variable?

• Changed on purpose by the scientist

• Measured as a result

• Stays the same in all trials

Which describes controlled variables?

• Changed on purpose by the scientist

• Measured as a result

• Stays the same in all trials

Identify the controlled variables in this experiment: How does the environment affect the height of the plant? Check all that apply.

• Environment the plant is in

• Height of the plant

• Type of plant

• Type of soil
