15. Stop Think And Review 1.Do scientists always follow the exact steps to the solving a problem? 2.What is ‘bias’? 3.What is ‘ethics’? No; the steps to the ‘Scientific Method’ is only a GUIDE. Partiality; prejudice; favoritism What society views as right & wrong

16. Ind. Var.= CAUSE Dep. Var.= EFFECT D = Effect X Y I = Cause

17. 1.Make a line graph that shows how many text messages you send between the hours of 7AM to 3PM. 2.Label X & Y axis 3.Detailed title with cause & effect IN the title #1 Graph this on a separate sheet Just make up the data

18. 1.Draw a graph that shows the change in daily temperature in degrees Fahrenheit on January 1 st through the 7 th. 2.The temperatures were 10, 25, 30, 42, 23, 25, and 40 respectively. 3.Label X & Y axis 4.Detailed title with cause & effect IN the title #2 Graph this on a separate sheet

19. GRAPH ‘QUIZ’ 1.Use white boards in drawer next to you 2.Use BLACK pen & eraser 3.I will give you 2 scenarios total 4.You will draw one graph at a time on the white board 5.Compare yours to mine 6.Ask questions 7.Erase 8.Put boards away.

20. Stop Think And Review D = Effect X Y I = Cause

21. GOOD HYPOTHESIS  Must be measurable  Must be objective bias  No bias BAD HYPOTHESIS  Opinions – not meas.  Not objective bias  Shows bias  prejudice; impartial judgment; showing favoritism  Good vs Bad What is a good Hypothesis?

22. 1. If a person exercises for 30 min/day, his or her pulse rate will go down by 5 beats/min. 2. Cats make better pets than dogs. 3. When I plant roses, they grow better than anyone else’s. 4. When 2 ounces of fertilizer is added to soil each day, the plants grow ½”/week. 5. If an owl flies along side of you, you will have good luck. 6. Dolphins make noises to communicate to the rest of the pack.  Good or bad? What makes a good hypothesis?

23. What is in a Hypothesis? 1.The CAUSE & the EFFECT!  Use If… then… format!  If I study a little each night, (CAUSE)  then I will get better grades. (EFFECT) 1.What’s in a Hypo- thesis? 2.Example : IV DV

24. IF = IV = Cause = X axis IF = IV = Cause = X axis THEN = DV = Effect = Y axis THEN = DV = Effect = Y axis DO

25. If the INDEPENDENT VARIABLE is ‘the cause’ & the DEPENDENT VARIABLE is ‘the effect’, then answer the following: Susan wants to find a way to spend more time with her family & still keep the peace at home… so instead of telling her kids that their friends can never come over again, she predicts that if she tells her kids’ friends that they can only come over on weekends, then she should have more quality time with her family… 1.What is the CAUSE of Susan spending more time with her family  the Ind. Var.? 2.What is the EFFECT of having friends over only on weekends  the Dep. Var.? Try this Having friends over only on weekends Quality time with family!

27. Page 17 Writing a Hypothesis 1.IF Justin listens, participates, & reads over his notes (CAUSE), THEN he will earn a ‘B’ in Biology (EFFECT) 2.IF Jill studies the lake in the summer when its warm (CAUSE), THEN it will be green & murky (EFFECT) ….. Or…. in the winter/cold it will be clear… 3.IF Kim waits until December when it’s cold (CAUSE), then she should be able to catch more lizards. (EFFECT) 4.IF Alicia wears pastel colored tops (CAUSE), THEN bees will not fly around her (EFFECT). … Or… wearing neon will attract bees
