Question

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.
identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?​

Answer 1

Answer:

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

Radiation does not have effect on strength of the mice

Explanation:

In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.

The control group is the group that does not receive treatment which is used to compare the effect of the treatment.

The control variable is another variable that must be held constant when performing the experiment.

Here the

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.
