1. Forming a Hypothesis
Tuesday, Aug. 28th

2. Purposes:
Content: Develop personal responsibility and make hypotheses based on observations of the natural world.
Language: Use an “if then” sentence frame to create hypotheses.
PWG Outcome: help your group form hypotheses for each inquiry.

3. First 20 days
Day 7 –Discuss with your partner what makes for good communication between students.

4. Hypothesis Structure IF
Then

5. How to make a hypothesis statement:
Hypothesis statements are ALWAYS written as "If ...Then" statements.

6. Example of a hypothesis
If I stay out in the sun for 3 hours then I will get a sunburn.

7. Changing my thoughts into hypotheses
I’m thinking: The higher the temperature of the water, the faster the egg will cook.
I write as a hypothesis: If I raise the temperature of the water then, the egg will cook faster
Or. . . If temperatures of water are raised, then the eggs will cook faster.

8. Changing my thoughts into hypotheses
I’m thinking: Lemon trees receiving the most water
produce the largest lemons.
I write as a hypothesis: If I increase the amount of water given to lemon trees, the size of the lemons produced will increase.

9. How to disagree agreeably

10. You try :
With the group: If I do this;______________ then ________________. (will happen)
With a partner: If I ___________________ then _________________.
By yourself: If ______________________ then ________________.

11. Example of a hypothesis
If I stay out in the sun for 3 hours then I will get a sunburn.

12. Determining Dependent and Independent variables
Independent Variable - Variable in an experiment that is changed or manipulated. I.V. - The amount of time spent in the sun Dependent Variable - The variable in an experiment that responds to the change and is measured. D.V. - Getting a sunburn

13. How could we change our hypothesis to provide for a more scientific experiment?
Measure using quantitative data versus qualitative data.
Vocabulary:
Quantitative Data: uses numbers and measurements
Qualitative Data: uses 5 senses to observe

14. Assignment
This week we will be creating an experiment from beginning to end. You will be following the steps of scientific inquiry (the scientific method).
You must think of something you would like to test.
Homework: come up with a question, observe or research something, and come up with a hypothesis statement.
