Meterstick Graduated cylinder Balance Hand lens 2. A shoe company claims in an advertisement that its athletic shoes are “for winners only.” The shoe company hopes that people who read the ad will infer which of the following about the shoes? They are designed for people who play only one sport. They are more expensive than other brands of shoes. They are likely to improve the athletic ability of people who wear them.

  9. What is a “control group”/ “constant”? Often in an experiment there will be a control group. Control Group: a group that seems just like the group you’re really testing, but does not receive any actual changes. REMAINS CONSTANT! For example, in the BrainPop video, the “control group” was the plant that was not watered at all. The results from the control group are used to compare to the results you got from the group you manipulated (in other words, the group you gave the independent variable).

  10. What is a “control group”? Sometimes when you use a control group, you might give them a placebo. Placebo – Not the real thing! Something that you give to your control group that looks exactly like what you’re giving to your experimental group, but isn’t really changing anything. For example, if I am testing whether a sports drink really works, I will give my “REAL” group the sports drink and I will give my “CONTROL” group regular water with food coloring in it. It will look exactly like the sports drink, but without any of the qualities that I’m testing for. That way, the group won’t be affected by thinking they’re the ones being tested.

  11. Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the KrustyKrab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems. Which group is the control group/constant?

  12. 2) Was there a placebo used? If so, what was it? • 3) What was Mr. Krabbs’ hypothesis? • 4) What is the independent variable? • 5) What is the dependent variable? • 6) What should Mr. Krabbs’ conclusion be? • 7) Why do you think 8 people in group B reported feeling better?

  13. Correcting Your Quiz… You have 1 opportunity to correct your quiz. You must make your corrections on a blank sheet of loose leaf paper and staple it to your original quiz. You should make NO changes to your original quiz. All new writing should be on the loose leaf paper. You will number the question you got wrong and write the correct answer next to the number. For the situations on the back, you will write in complete sentences. If you do not write in complete sentences, you will not receive the points back.

  14. Correcting Your Quiz… How many points will I get back? If you make the correction right and follow ALL directions, you will receive HALF of the points back. For example, if you left an answer blank or got it completely wrong, you’ll get ½ a point back (50%). If you got a question half (1/2) right, you’ll get ¼ of the points back. So if my grade now is a 40, I can turn that into a 70 if I make all my corrections.

  15. Your paper should look like this…. John Student H.M.S August 30, 2010 Science, Period 1, Ms. Arter Lab Equipment & Safety Quiz Corrections Multiple Choice: 3. Scalpel Situations: 6.
