1. Variables: Notes

2. What are VARIABLES???
Variables are an important part of science projects and experiments.
Basically, a variable is any factor that can be controlled, changed, or measured in an experiment.
Scientific experiments have several types of variables.

3. 3 Types of Scientific Variables:
Independent Variable
Dependent Variable
Control Variable

4. Independent Variable:
The independent variable is the one condition that you change or manipulate in an experiment.
You can choose this…
EX: In an experiment testing how light affects plant growth, the type of light or amount of light used is the independent variable.

5. Dependent Variable:
The dependent variable is the variable that you measure or observe.
This variable responds to the independent variable....
EX: In an experiment testing how light affects plant growth, the growth of the plants is the dependent variable.

6. Control Variable:
A controlled variable or constant variable is a variable that does not change during an experiment.
This variable remains the SAME throughout the experiment.
EX: In an experiment testing how light affects plant growth, the type of plant would be the control variable.
