1. Problem solving using the scientific method

2. What are the steps? Observe a problem State the problem Research the problem Make a hypothesis Test your hypothesis Review your results Conclusion- Redo hypothesis and retest or repeat first hypothesis

3. OBSERVE the PROBLEM: Tell me what it is….

4. STATE the PROBLEM - Can be more than one Steroids –Unfair advantage –Health Risks –Negatively viewed by public –Loss of income –Shame

5. What problem do you think people think about the least about steroids? :30 1.Unfair Advantage 2.Health Risks 3.Negatively viewed by public 4.Loss of income 5.Shame 1234567891011121314151617181920 21

6. What do you know about the problem for everyone RESEARCH the PROBLEM premature balding or hair loss mood swings, anger, aggression, and depression believing things that aren't true (delusion) extreme feelings of mistrust or fear (paranoia) problems sleeping, Nausea, vomiting, trembling high blood pressure that can damage the heart greater chance of injuring muscles and tendons urinary problems shortening of final adult height risk of developing heart disease, stroke, cancer

7. What do you know about the problem For MEN RESEARCH testicular shrinkage pain when urinating breast development impotence (inability to get an erection) sterility (inability to have children)

8. What do you know about the problem for WOMEN RESEARCH increased facial hair growth development of masculine traits, such as deepening of the voice, and loss of feminine body characteristics, such as shrinking of the breasts menstrual cycle changes

9. What is your HYPOTHESIS about the problem? ( Your educated guess as to what will happen) If a male takes steroids, then they will have at least 1 more problem compared to a female… MUST HAVE IF AND THEN

10. TESTING YOUR HYPOTHESIS In this case, can we do a quick lab in class to figure out if we are right or not???? –NO We have to set up a long term test More than one person Same amount of time Same amount of drugs Same type of drugs Same sport

11. Keeping things the same….Why? Everything that can be controlled in an experiement is called a variable In an experiemnt, we want to keep almost everything the same. We call them constant variables. Constant variables allow us to eliminate those things from being part of the problem since they are the same for everyone.

12. Which would be a variable in a experiment involving steroids and health? :45 1.People 2.Types of Steroids 3.Heart 4.Muscles 5.1 & 3 6.2 & 4 7.All the Above 8.None of the Above 1234567891011121314151617181920 21

13. Which would not be a variable in an experiment about candy’s effect on attention spans. :45 1.Snickers Chocolate bar 2.Being hyper 3.Soda 4.1 & 2 5.All 6.None 1234567891011121314151617181920 21

14. If everything is the same what are we testing? We change only one thing… Like testing males and females. This is called our independent ( or manipulated) variable.

15. How do we know if we found something? If anything happens differently in the experiment we call it the dependent or responding variable What would we expect to happen in this experiment? We would expect that males would RESPOND more than women.

16. What do we do with the results? CONCLUSION Once we get the results we compare them with our hypothesis and we say if we were right or wrong. Then we spend the next few sentences talking about how we could make the experiment better or what went wrong in our experiment.

17. What if our hypothesis was wrong? Change your hypothesis and test it again. Scientists will often change and retest hundreds or thousands of times

18. What if my hypothesis was right Test it again!!! Why? Because the more you do it and you are right, the more valid or truthful your hypothesis becomes

19. So what are the steps? Observe a problem State the problem Research the problem Make a hypothesis Test your hypothesis Review your results Conclusion- Redo hypothesis and retest or repeat first hypothesis
