1. Warm-Up What is an Observation? What is a Conclusion? List the steps of the scientific method: After you have written and answered these questions work on your vocabulary.

2. Scientific Method What looks wrong with this picture?

4. The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? And, in order for the scientific method to answer the question it must be about something that you can measure, preferably with a number. Ask Question or Think of Problem

5. Research You have to research the problem look into why it e xist, other attempts to fix it and why they didn’t work. Learn about the topic!

6. Hypothesis Activity

7. Hypothesis Your hypothesis should state what you think will happen your prediction for the outcome of this experiment. You must state your hypothesis in a way that you can easily measure, and of course, your hypothesis should be constructed in a way to help you answer your original question.

8. Experiment Test Your Hypothesis by Doing an Experiment! Your experiment tests whether your hypothesis is true or false. It is important for your experiment to be a fair test. –You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same. You should also repeat your experiments several times to make sure that the first results weren't just an accident.

9. Analyze Analyze your Data from the Experiment! Once your experiment is complete, you collect your measurements and analyze them to see if your hypothesis is true or false. Did the experiment have the results you expected or did something different happen? Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the entire process of the scientific method over again.

10. After you have carefully analyzed your data you can draw your conclusions based on the results of this experiment. It is key that you do not make any conclusive statements until you have completed the experiment and know the data. Conclusion

11. Variables Experiments have different variables An independent variable is a factor that is manipulated in an experiment. –The experimenter controls whether or not subjects are exposed to the independent variable. The dependent variable is measured to determine if the manipulation of the independent variable had any effect. Constant- doesn’t change - Controls are used to show that results of an experiment are actually a result of the condition being tested.

12. Example To test a hypothesis that eating carrots improves vision, the experimenter would manipulate whether or not subjects ate carrots. –Thus, eating carrots is the independent variable. Each subject’s vision would be tested to see if carrot eating had any effect. –Thus, vision is the dependent variable. The subjects assigned to eat carrots are in the experimental group, whereas subjects not eating carrots are in the control group.

14. Make up your own EXPERIMENT YOU DO NOT ACTUALLY HAVE TO PERFORM THE EXPERIMENT! JUST DESIGN IT! Work in groups to think of an experiment that you could design. Make a poster that answer all the following info. You can use pictures & diagrams Go through all 6 steps of the Scientific Method. Explain the problem Why you want to do this experiment. Have a Hypothesis. How you would carry it out to test your Hypothesis. How you would analyze the data. What conclusions you would be able to draw at the end of this experiment.
