9. Practice with Hypotheses What is the effect of cigarette smoke on household plants? If I test to see how cigarette smoke affects household plants, then I will find that … OR If I put plants in an environment with lots of cigarette smoke, I will find that …

10. Practice with Hypotheses Which brand of laundry detergent is best at getting rid of stains? If I test a variety of laundry detergent to see which one gets rid of stains the best, then I will find that…

11. Practice-Write Hypotheses Which brand of soap gets rid of germs the best? What is the best amount of sunlight and water for growing violets? Which brand of sneakers will allow you to jump the highest? How are student grades affected by the amount of time spent viewing television?

12. __________________________________________________________________ _______________________________ Should test only ONE variable at a time.

13. Conclusio n 1.Tells if hypothesis was correct or not. 2.Explains WHY hypothesis was correct or not. 3.Uses data from the experiment as evidence to support.

14. Draw this table on page 12 of your Science Journal. You will complete this table as you do the next activity. Observation Hypothesis ______________________________________________________________________________________________________ Step 3 Step 4 Step 5 Step 6

16. Exit Slip: What is the difference between a hypothesis and a conclusion?

17. Tuesday August 16 th DO NOW What is the difference between an observation and a hypothesis?

18. PLAN Identify the observation, hypothesis, experiment, and conclusion component in a lab experiment. DO We will complete the Checks Activity to practice using the observation and hypothesis steps of the Scientific Method. (10 mins. max) Briefly review possible hypotheses. Discuss variables in an experiment. Complete Sling Shot Lab.

22. Variables in an Experiment “I” changeMeasured Constant Stays the same

23. MIX DRYDRY

24. Independent Variable: “I” change it Manipulated variable MIX

25. Dependent Variable Depends on the independent variable It is the Response DRY

26. Sling Shot Lab Materials: slingshot, dice, meter stick, masking tape Distance of pulled band. Distance dice traveled. 2 cm 3 cm 4 cm

27. Sling Shot Lab 1.Gather materials 2.Place the slingshot at the “starting position” mark this with a piece of tape. 3.Use the meter stick determine the distances for rubber band pull back (2 cm, 3 cm, and 4 cm) 4.Place the dice on the rubber band and pull back to the first distance, release and observe the distance it travels. 5.Measure and Record onto the data table. *Repeat for remaining rubber band pull distances.

28. Homework: Use the data collected by your group to: Make a line graph (remember to label) Identify independent variable Identify the dependent variable
