Question

Bart believes that mice exposed to radiowaves will become extra strong (maybe he's been reading too much Radioactive Man). 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 mouse 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. Identify the:___________-
1. Control Group
2. Independent (Manipulated) Variable
3. Dependent (Responding) Variable
4. What should Bart's conclusion be?
5. How could Bart's experiment be improved?

Answer 1

1) Mice not radio waved.

2) Radio

3) Strength of mice

4) Maybe inconclusive.

5) Improves strength

Explanation:

1. Control Group - Mice not radio waved.
2. Independent Variable - radio.
3. Dependent Variable - Strength of mice.
4. What should Bart's conclusion be? Maybe inconclusive.
5. How could Bart's experiment be improved? Improves strength

Experimental setup

setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.

Control Setup

setup that is identical to the experimental setup, only it does not contain a variable.

Independent Variable

The one factor that is change by the person doing the experiment

Dependent Variable

The factor which is measured in the experiment

Constant

all the factor that stay the same in an experiment.
