Question

homer notices that his shower is covered in a strange green slime. his friend barney tells him that coconut juice will get rid of the green slime. homer decides to test this out by spraying half of the shower with coconut juice. he sprays the other half of the shower with water. after 3 days of \treatment\ there is no change in the appearance of the green slime on either side of the shower. 6. what was the initial observation? identify the - 7. control group 8. manipulated (independent) variable 9. responding (dependent) variable 10. what should homers conclusion be? bart believes that mice exposed to microwaves will become extra strong (maybe hes been reading too much radioactiveman.) he decides to perform this experiment by placing 10 mice near a radio for 5 hours. 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 mouses food. he found that 8 out of 10 of the radiowaved mice were able to push the block away. 7 out of 10 of the other mice were able to do the same. 11. what was barts hypothesis? identify the 12. control group 13. manipulated (independent) variable 14. responding (dependent) variable 15. how could barts experiment be improved?

Explanation:

1. Homer noticed his shower was covered in a strange green slime.
2. The half of the shower sprayed with water is the control group as it doesn't receive the treatment (coconut - juice).
3. The substance sprayed (coconut juice or water) is the independent variable.
4. The appearance of the green slime is the dependent variable as it is what is being measured for change.
5. Homer should conclude that coconut juice does not get rid of the green slime.
6. Bart's hypothesis is that mice exposed to microwaves will become extra strong.
7. The 10 mice that had not been exposed to the radio (microwaves) are the control group.
8. Exposure to microwaves (placing near a radio) is the independent variable.
9. The strength of the mice (ability to push the block away) is the dependent variable.
10. Bart could use a proper microwave source for exposure, increase the sample size, and repeat the experiment multiple times for more accurate results.
