Here's a project that combines sports and math. You'll learn how to use correlation analysis to choose the best team batting statistic for predicting run-scoring ability (Albert, 2003). You'll also learn how to use a spreadsheet to measure correlations between two variables.
Is there a correlation between birth order and grade point average? Design a survey study to find out. How many completed surveys do you need for a representative sample of your school? If you limit your survey to one school, would you expect it to be representative of a larger population (such as your county or state?) How do you control for potential effects of parental age at birth? (In other words, younger siblings will have a higher probability of being born to older parents. If there…
This project asks the question "How do friendship groups change over time?" The results may support inferences about how "people skills" develop. What types of changes would you expect to see? Do you expect friendship groups to grow larger over time? Do you expect that individuals will belong to more, less or about the same number of friendship groups as they get older? Do you think there will be more or less exclusivity among groups (and how would you measure such a concept)? Do you…
Antioxidants have become very popular in the news lately for their potential health and anti-aging properties. Antioxidants work by preventing oxidation reactions that produce free-radicals which can cause harm to the body. Try testing different vitamins for antioxidant activity. How do vitamins A, B, C, and E compare? Do some vitamins have more antioxidant activity than others? What are some other sources of antioxidants? Try testing extracts from proposed sources of antioxidants like coffee,…

Here's a project that will give you insight into accidents, and maybe help you prevent them. The original project used a survey method to gather data, which you could also do. Another approach for data collection that you might try would be to use published articles from the pediatric medical literature. Finding a pediatrician or pediatric orthopedist who is willing to be your mentor for this project would be helpful. (Idea from Caito, 2003)
The concept of beauty changes over time and often differs among societal groups. How strongly do societal conceptions of beauty shape an individual's self-image? There are many fascinating questions you could choose to explore with surveys on this subject. For example, how well do girls' ideas of what is attractive in boys agree with boys' expectations about what girls find attractive (or vice versa)? Try your survey with different generations to see how conceptions change over time. If you…
You can compare the picture quality for photos taken at different shutter speeds with the camera handheld vs. with the camera on a tripod. (This is best done with a camera that has manual exposure control.)
