1. Controls and Constants

2. Review

3. Review
In an experiment, because the scientist is changing this independent variable, this is going to change and the scientist will measure that change…

4. Review
This is an educated guess of what is going to happen during an experiment – the scientist forms this at the beginning of the experiment….

5. Did You Get Them Right? Independent Variable Dependent Variable
Hypothesis

6. Constants and Controls

7. Constant
Constant: something that scientist makes sure is the same throughout the experiment
Ex. Watering the plants the same amount of water or making sure you are testing the same person every time

8. Control
Control: The part of the experiment that the scientist doesn’t change or add the variable to
Ex. The plant with the white light

9. Conclusion
The results of the experiment; is your hypothesis “right or wrong”?
