1. The Scientific Method

2. General Information: Scientific Method:
The process that is used to find out about the world and to answer questions
- they all have a problem
- they all perform an experiment

3. General Information: Hypothesis: Testable predictions
Theory: Explanations supported by experiments
Variable: Something in an experiment that can change

4. General Information: Independent Variable: A variable that is changed
Dependent Variable: What is being measured
Constants: Variables that stay the same

5. General Information:
Frequency : The number of items occurring in a given category
Percent: A proportion multiplied by 100
Percent = # of red candies
total candies

6. The steps of the scientific method:
Identify the problem
Gather the information
Form a hypothesis
Experiment
Analyze data
Communicate results

7. Identify the problem: What do you want to know or explain?
Write a question that addresses the problem or topic

8. Gather the information:
How will you test your hypothesis?
Develop a reliable experiment and address safety rules

9. What is a hypothesis?
It is a prediction based on observations and your knowledge of the topic.

10. Form a hypothesis: What do you think will happen?
Make observations and use prior knowledge
Predict an answer or outcome

11. Perform an experiment:
Follow the steps in your procedure to perform your experiment
Record data and observations!

12. What is data?
It is information gathered during an experiment.

13. Analyze data: Is the data reliable?
Does your data and observation support your hypothesis?

14. If yes – communicate the results:
Write a conclusion that summarizes the important parts of your experiment and the results

15. If no: If the answer was no: modify the experiment in some way
Is your data inaccurate or is the experiment flawed?
If the answer was no: modify the experiment in some way
Rewrite your procedure to address the flaws

17. The End!!
