The first part of the assignment is the selection of your topic. We will work on Part II in class, and you may have time for Part I as well. You will need to work on this at home!

Part II
Bancroft Library Research Link (brainstorming process and research links!)
Independent Variable (Cause, I change): This variable causes something to happen to the dependent variable. The scientist changes the independent variable on purpose.
Dependent Variable (Effect, what you measure): This variable has something happen to it as a result of the independent variable. The dependent variable changes in response to the independent variable. The dependent variable is the variable the scientist measures.
Example Statement of the Problem:
How does the pH of water affect the rate of corrosion of iron?
Independent variable/cause: pH above 7.0, pH below 7.0, and pH 7.0
Dependent variable/effect: Will iron nails rust faster or slower in the different conditions?
