1. Scientific Method

2. Problem or Question
Research
Hypothesis
Procedure
Observations
Data
Conclusion

3. Hypothesis
A possible explanation for observations that relate to a scientific question
Must be testable by observation or experiment
It is a Scientific “Guess”
Example: I think that if I water the plant everyday it will grow.

4. You use all five of these to gather information
Observation
Uses all five senses
Sight
Hearing
Touch
Smell
Taste
You use all five of these to gather information

5. Data
Observations and measurements recorded during an experiment

6. Controlling Independent Dependent Variables
Factors that can CHANGE during an experiment
3 Types of Variables
Controlling
Independent
Dependent

7. Controlled
Variable
The variable that stays the SAME
Example: You have two plants that are both in the same pot, with the same amount of soil, the same amount of seeds and have the same amount of water. You place one in front of the window and the other in a closet. After two weeks you measure to see the growth of each of the plants.

8. Independent Variable The variable that the scientist CHANGES
Manipulated variable
Example: You have two plants that are both in the same pot, with the same amount of soil, the same amount of seeds and have the same amount of water. You place one in front of the window and the other in a closet. After two weeks you measure to see the growth of each of the plants.

9. Dependent Variable The variable that the scientist Measures
Responding variable
Example: You have two plants that are both in the same pot, with the same amount of soil, the same amount of seeds and have the same amount of water. You place one in front of the window and the other in a closet. After two weeks you measure to see the growth of each of the plants.

10. Results
There are many different ways to organize the data into your results

11. Compare Hypothesis to the Data How to begin….
Conclusion
Compare Hypothesis to the Data
How to begin….
According to my data, my hypothesis was right or wrong because…. I think this happened because….If I were to do this experiment again I would…..

12. Scientific Law
A statement that describes what scientists expect to happen EVERY time under a particular set of conditions.
Example: Law of gravity …what goes up will come down…(happens every time)

13. Scientific Theory
A well-tested idea that explains and connects a wide range of observations.
Can be changed because of new evidence
Example: My theory is that everyone in this class will get an A+ on their first test
