October 09, 2014 Does increasing the amount of water I give my house plants affect their growth? Hypothesis Experimental Control Manipulated/Independent Variable Responding/Dependent Variable Constant Variables Experiment Conclusion October 09, 2014 Does increasing the amount of water I give my house plants affect their growth? Hypothesis - If the plants are watered more, then their growth will increase because plants need water to photosynthesize.

Hypothesis - If the plants are watered more, then their growth will increase because plants need water to photosynthesize. Experimental Control Manipulated/Independent Variable Responding/Dependent Variable Constant Variables Experiment Conclusion October 09, 2014 Patty Power Control Group = people that got the regular mayo sauce -Group B Independent variable = type of sauce Dependent variable = amount of gas (stinky!) Mr. Krab's should conclude that the new sauce seems to reduce gas production since 60% of the test group improved but does not work 100% of the time. 8 people may have had the "placebo effect" believing they were having the new sauce. October 09, 2014 Slimotosis Sponge Bob observed slime on Gary's shell and an odor coming from the shell. Independent variable = type of treatment **used 2 at the same time which is not OK Dependent variable = amount of slime and odor Sponge Bob cannot conclude anything specific. He will need to test each remedy separately to see those results first. Is it rubbing seaweed? Is it drinking Dr Kelp? Is it the combination of the 2? No control....does slimotosis just go away on its own? October 09, 2014 Marshmallow Muscles Control group = Sponge Bob Independent variable = type of lotion rubbed on Dependent variable = amount of strength increase Larry should conclude that _________________. Why??? October 09, 2014 Microwave Miracle Hypothesis - If....then.... If fish eat microwaved food, then they will improve their maze solving time. Control = the fish that got regular food Independent variable = type of food they ate Dependent variable = time in the maze Patrick should conclude that ____________. Why???

Homework Debrief Warm-up Poem Back to Bikini Bottom Assignment: Experimental Design WKST Quality Control Check October 09, 2014 Jim, Jody, and Juan, all sixth graders, love to play tennis and are interested in forming an interscholastic tennis team. Mr. Bingham and Mr. Hlavacek agree to coach a team and hold tryouts at the end of October. In order to create excitement about a team and encourage students to try out they decide to hold tennis practice sessions after school every day for two weeks. Seeing as how this was their idea, Jim, Jody, and Juan want to make sure that they will make the team. To ensure their placement on the team, they test to see which brand of tennis ball helps produce the fastest serve. Jim, Jody, and Juan believe that if they determine the ball that produces the fastest serve, they will definitely make the tennis team because they will have an advantage over the other players. Before completing the experiment, they all think that Penn tennis balls will bounce the highest because they are the hardest to squeeze. Using Penn, Wilson, and Dunlop tennis balls, they decide to drop each ball from 15 meters above the ground onto a clay tennis court. They measure the height that each ball bounces and record this value in their data table. Jim, Jody, and Juan complete five trials for each tennis ball and record an average height in their data table.

Focus: Consider ALL evidence and information. Think about the validity of the experiments. Be sure to support your conclusions. October 09, 2014 Krusty Krab Breath Mints 1) Control = the people who received the mint without the secret ingredient - group B 2) Independent variable = secret ingredient in the mint 3) Dependent variable amount of breath odor (bad breath) 4) Mr. Krab's can conclude that the breath mint with the secret ingredient appears to reduce the amount of breath odor more than half the time, but it is not 100% effective. 5) possible placebo effect October 09, 2014 Sponge Bob Clean Pants 6) SpongeBob's pants were not clean. 7) Independent variable = type of laundry soap 8) Dependent variable = amount of dirt left on the pants (or how clean the pants were) 9) Sponge Bob should conclude that Clean-O laundry soap does not appear to be effective in cleaning his pants. October 09, 2014 Squidward's Symphony 10) Independent variable = type of instrument played 11) Dependent variable = number of jellyfish that came 12) The clarinet did seem to attract a large number of jellyfish, but the average number for the 3 trials also matched the average for the guitar. The flute attracted the least number of jellys, but the average for this category is still larger than the control. Music seems to attract the jellys in greater numbers than when no music is played. Therefore, Squidward's hypothesis that the clarinet attracts larger numbers of jelly fish than other instruments is not proven by this experiment alone. 13) Based on the limited amount of information provided, it is difficult to tell if Squidward's results are reliable. The description did not tell how long each break was between trials. Did he leave enough time for the jellyfish to "clear out" of the area? ETC October 09, 2014 Super Bubbles 14) The ads claimed that the Super Bubble solution would produce bubbles that were twice as large as those made with regular soap. 15) Independent variable = type of bubble solution 16) Dependent variable = size of the bubble (diameter) 17) Super Bubble = 15.1 cm Regular Soap = 11.5 cm Patrick should conclude _______. Why??? 18) Valid? Why or why not? October 09, 2014 Mrs. Olson believes there is a connection between students' diets and their performance in science class. She knows vegetables are "brain healthy" and many students don't eat enough of them. She believes increasing broccoli (her personal favorite) consumption will help student scores. Period 4 is required to eat a pound of broccoli each week, Period 5 is required to 2 pounds of broccoli each week and Period 8 is allowed to continue with their regular diet. Mrs. Olson plans to monitor grades on quizzes and tests over the course of the next quarter. She will compare quiz and test averages at the end of the experiment. 1) IND Variable / DEP Variable 2) Write a Hypothesis Statement for Mrs. Olson 3) Control 4) A Constant Variable October 09, 2014 Science Friday 10/10/14 Today's Focus: What are the components of experimental design? Differentiated Labs - Green Cart Mrs. Olson - small group instruction Assignment: None October 09, 2014 1. Control Group -- Group B 2. Independent Variable -- Drink consumed 3. Dependent Variable -- #of stacks of papers stapled 4. What should Smithers' conclusion be? the special juice doesn't work to improve work productivity 5. How could this experiment be improved? 6. What was the initial observation? Slime on the shower Identify the7. Control Group - Side sprayed with water 8. Independent Variable - Spray used to clean (the coconut juice) 9. Dependent Variable - Appearance/amount of Slime 10. What should Homer's conclusion be? Coconut juice does not remove shower slime. October 09, 2014 Identify the11. Control Group - Mice not exposed to radio waves 12. Independent Variable - amount of radio waves they are exposed to 13. Dependent Variable - Strength of mice 14. What should Bart's conclusion be? Although the "radiowaved" mice outperformed the control group, it was by a very small amount - 10%. Therefore, he should probably run further tests. 15. How could Bart's experiment be improved? Identify the16. Control Group - Subject A 17. Independent Variable - powder 18. Dependent Variable - length of itchiness 19.
