technology
These are the variables that are kept the same between the groups in an experiment
controlled variables
How many independent variables should be tested in an experiment?
one

The students
The scientific method is not a simple linear process, but rather an ________ one because it repeats over and over and continues to make improvements.
iterative
If a hypothesis is tested and succeeds over and over, it becomes a scientific ___________
theory
This groups receives the independent variable. It is the subject of the experiment.
experimental group
The data from an experiment is the _________ variable.
dependent
This person is the most important part of lab safety

This variable changes because the independent was manipulated...
the dependent variable
After you have established your question or problem, which step of the CER method should you do first?
