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 same.

identify the-

1. control group

2. independent variable

3. dependent variable

4. what should bart's conclusion be?

5. how could bart's experiment be improved?

An experimental design must contain three variables: variable to be studied (dependent variable), a variable which can be manipulated (independent variable) and the variable which is kept constant (constant variable).

The experimental samples are categorized into two groups: the experimental group om which experiment is performed and the control group on which the independent variable is missing.

Therefore in the given question: The study was conducted to study the effect of microwaves on mice, so the  

1. Independent Variable  - the variable to be studied strength of mice.

2. Dependent Variable  - the variable which can be manipulated in 10 seconds (time).

3. Control Group- the samples which lack microwave radiation that is mice not exposed to microwave.

4. Bart's conclusion is- microwaves do not affect the strength of the mice as the experimental mice pushed the block nearly the same to the control group.

5. Improvement- The experiment can be improved by taking a large sample size to reduce the error.

cuz they cant breath

explanation:

the match lol
