  • These aren't all correct, Krusty's last question 45 is 50% more than 30.

    Also for #5 retest it wouldn't be changing the experiment at all, Having them drink the juice prior to working would be an appropriate answer.

    • Identify the Controls and Variables Smithers thinks that a special juice will increase the Identify the: productivity of workers. He creates two groups of 50 workers each and assigns each group the same task 1. Control Group: Group B (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink 2. Independent Variable: Special Juice while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B 3. Dependent Variable: Productivity of workers made 2,113 stacks. 4. What should Smithers' conclusion be?: The special juice did not increase workers productivity 5. How could this experiment be improved? Retest it! Homer notices that his shower is covered in a strange 6. What was the initial observation?: Green green slime. His friend Barney tells him that coconut slime in the shower juice will get rid of the green slime. Homer decides to check this this out by spraying half of the shower Identify the- with coconut juice. He sprays the other half of the 7. Control Group: Side he sprayed with water shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on 8. Independent Variable: Coconut Juice either side of the shower. 9. Dependent Variable appearance of green slime 10. What should Homer's conclusion be? Coconut juice did not reduce the amount of slime in the shower Bart believes that mice exposed to microwaves will become extra strong Identify the- (maybe he's been reading too much Radioactive Man). 11. Control Group Mice that had not been He decides to perform this experiment by placing 10 exposed mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. 12. Independent Variable: microwave His test consisted of a heavy block of wood that blocked the mouse food. he found that 8 out of 10 of the 13. Dependent Variable: Strength of the mice microwaved mice were able to push the block away. 7 out of 10 of the non-microwaved mice were able to do the same. 14. What should Bart's conclusion be?: Microwaving did not cause the mouse to be stronger than non microwave mice 15. How could Bart's experiment be improved? Retest it Krusty was told that a certain itching powder was the Identify the- newest best thing on the market, it even claims to cause 16. Control Group Group A 50% longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual 17. Independent Variable: Experimental Itching product. One test subject (A) is sprinkled with the original Powder itching powder, and another test subject (B) was sprinkled with the Experimental itching powder. Subject A reported 18. Dependent Variable: Itchiness time having itches for 30 minutes. Subject B reported to have itches for 45 minutes. 19. Explain whether the data supports the
