Question

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. Bart's hypothesis is that mice exposed to microwaves will become extra - strong.
2. The control group is the 10 mice that had not been exposed to the radio (microwaves in his hypothesis context).
3. The manipulated (independent) variable is the exposure to microwaves (in this case, exposure to the radio).
4. The responding (dependent) variable is the ability of the mice to push the heavy block of wood.
5. The experiment could be improved by using a proper microwave source instead of a radio, increasing the sample size of mice, and conducting multiple trials.

Answer:

1. Mice exposed to microwaves will become extra - strong.
2. The 10 mice not exposed to the radio.
3. Exposure to microwaves (exposure to the radio).
4. The ability of the mice to push the heavy block of wood.
5. Use a proper microwave source, increase sample size, conduct multiple trials.
