5. Six Steps!
(2) State the question
(3) Gather information
(4) Formulate a hypothesis: an educated guess

6. Six Steps!
(5) Perform experiments to test whether the hypothesis is true
(6)Analyze data
(7)Draw conclusions from the data

7. S: State the Question
Before you begin an experiment, you must first ask a scientific question. Make sure it’s testable
Ex: How does eating Wheaties effect how much weight I can lift

8. Before you make a hypothesis, you should research your question
G: Gather Information
Before you make a hypothesis, you should research your question
Ex: Read all the research you can find on Wheaties

9. F: Formulate a hypothesis
A Hypothesis is: a suggested explanation about the question you asked. A hypothesis must always be:
Testable
Show cause and effect
Be based on earlier research

10. P: Perform Experiments
This is when you actually perform your experiment
You must have materials and a step by step procedure

11. A: Analyze Data
During this step, you should organize your data into tables and charts. Then you should make graphs so you can analyze your experiment

12. D: Draw Conclusions You decide if your hypothesis was correct.
Ex: In conclusion eating Wheaties does cause a person to gain muscle mass making it possible for them to become stronger.

13. Making a good hypothesis
A. A good Hypothesis must be
I: Based on earlier research
II: A complete sentence
III: Show cause and effect
IV: Contain a reason to support your prediction

Identify cause and effect: 3.) The students got wet because of the rain. Cause: rain Effect:

22. Road Check
Identify cause and effect: 3.) The students got wet because of the rain. Cause: rain Effect: students got wet

23. Making a good hypothesis
B. Cause and effect:
I: Cause: The reason something happens
II: Effect: The result of what happens
III: A Hypothesis PREDICTS that cause and effect
1.) Example: Sunlight Causes plants to grow
2.) Example: Plants that get less sunlight will grow less

24. Road Check: Make a good hypothesis for the following scientific questions
1.) Scientific Question: Does sunlight increase the rate at which a plant will grow?
A GOOD Hypothesis:

25. Road Check: Make a good hypothesis for the following scientific questions
1.) Scientific Question: Does sunlight increase the rate at which a plant will grow?
A GOOD Hypothesis: The amount of sunlight will increase the rate of plant growth.

2. What effect will radiation have on tumor size?
A GOOD Hypothesis:

27. 2. What effect will radiation have on tumor size?
Road Check: Make a good hypothesis for the following scientific questions
2. What effect will radiation have on tumor size?
A GOOD Hypothesis: The higher the amount of radiation, the smaller the tumor will get.

28. Road Check: Make a good hypothesis for the following scientific questions
3.) Does sleeping during the day effect how long a person sleeps at night?
A GOOD Hypothesis:

29. Road Check: Make a good hypothesis for the following scientific questions
3.) Does sleeping during the day effect how long a person sleeps at night?
A GOOD Hypothesis: The more sleep a person gets during the day the less sleep he or she will get at night.
