THe hypothesis to a lab was that plants grow faster in green light. Students observed the plants and recorded their observations. They oberveed that there was no change in the plants. What is the dependent variable in the experiment?
The part of the experiment that changes during the experiment; gather data.
less oxygen would be obtained, less carbon dioxide would be released
Take in oxygen and release carbon dioxide.
Eliminate waste from the body.
Transport materials through the body.
The part of the experiment that you change.
how fast the plant grows
The part of the experiment that is used for comparison.
