He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special is not given the special juice. After an hour, Smithers counts juice to drink while they work. Group B how many stacks of papers each group has made. Group A 2. Independent Variable 3. Dependent Variable 4. What should Smithers' conclusion be? made 1,587 stacks, Group B made 2,113 stacks.. 5. How could this experiment be improved? Homer notices that his shower is covered 6. What was the initial observation? in a strange green slime. His friend Barney tells him that coconut juice will Identify the- get rid of the green slime. Homer decides 7. Control Group to check this this out by spraying half of the shower with coconut juice. He sprays 8. Independent Variable the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green 9. Dependent Variable slime on either side of the shower. 10. What should Homer's conclusion be? Identify the- 11. Control Group Bart believes that mice exposed to microwaves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food, he found that 8 out of 10 of the microwaved mice were able to push the block away. 7 out of 10 of the non-microwaved mice were able to do the 12.
