a possible answer to a scientific question.
iv dv control variables hypothesis

Explanation:

1. The variable the scientist is looking at as the results of the experiment is the dependent variable (dv) because it is affected by the changes made in the experiment.
2. The variable the scientist is testing (changing) in an experiment is the independent variable (iv) as it is the one that is manipulated.
3. Variables that are kept the same/constant are control variables to ensure that only the independent - variable affects the dependent variable.
4. A possible answer to a scientific question is a hypothesis.

Answer:

1. dv
2. iv
3. control variables
4. hypothesis
