Science Process Review Sheet
comparative investigation -
descriptive investigation -
experimental investigation -
What is the scientific method?
independent variable -
dependent variable -
control -
data -
Bart believes that mice exposed to radio waves 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 radio waved mice were able to push the block away. 7
out of 10 of the other mice were able to do the same.
Identify the:
control group:
independent variable:
dependent variable:
