How To Research Science Fair Topic(s). 10-20 Points for most detailed answer!?

I've been told to narrow it down to 3 topics that I would like to do for my Pre-Ap Biology class. I've chosen:

1. The Effect of Soft Drinks Upon Digestion under Biochemistry

2. Fluctuation of a Liquid In The Container under Physics

3. The New Magic Formula for Eliminating Bad Breath under Chemistry

I have to research these topics -- read & educate myself w/ anything related w/ each project. I have to list 3 resources for each project idea. Can someone tell me where to look to research these 3 topics? I've used my search engine -- it's not really helping? Any Ideas please, 10-20 Pts. for most detailed answer!!!!!!! Thank you!

    Try http://www.pubmed.org There is a YouTube tutorial on how to use it. Use the advanced searched and search for Text Words related to your topic.

    For example, I entered "soft drinks" and "digestion" for a search and found the abstract for this article:

    http://www.ncbi.nlm.nih.gov/pubmed/18257753

    Obes Rev. 2008 Mar;9(2):151-64.

    A short history of beverages and how our body treats them.

    Wolf A, Bray GA, Popkin BM.

    Numerous studies have demonstrated that beverages containing sugar, high fructose corn syrup (HFCS) or alcohol are handled differently by the body than when sugar or HFCS are incorporated in solid foods and as a result the overall caloric intake from solid food does not adjust to account for the calories in these beverages. A consideration of our evolutionary history may help to explain our poor compensatory response to calories from fluids. This paper reviews the history of eight important beverages: milk, beer, wine, tea, coffee, distilled alcoholic beverages, juice and soft drinks. We arrive at two hypotheses. First, humans may lack a physiological basis for processing carbohydrate or alcoholic calories in beverage because only breast milk and water were available for the vast majority of our evolutionary history. Alternatives to those two beverages appeared in the human diet no more than 11,000 years ago, but Homo sapiens evolved between 100,000 and 200,000 years ago. Second, carbohydrate and alcohol-containing beverages may produce an incomplete satiation sequence which prevents us from becoming satiated on these beverages.
