What causes the most stress for teenagers? Is it school? family relationships? peer pressure? worries about the future? Design a survey to find out what contributes to teens' stress levels. Possible variations include: How do teenagers deal with stress? Are today's teens more or less stressed than their parents were as teenagers? Were the sources of stress the same for your parent's generation or different? (Idea from De Biasi, 2003) Read more

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… Read more

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… Read more

Many industries rely on scale models to develop new products and designs. Architects, industrial designers, artists, clothing designers, and car manufacturers all use scale models. Each model is built to a scale that relates the actual object to the model through a ratio. Can you determine a formula for constructing a scale model? You can use your formula to make a model of your house, school, neighborhood, or town (CUBE, 2002). You can make scale models of the Wright Brothers aircraft… Read more

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… Read more

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,… Read more

Some sequences of RNA can catalyze biochemical reactions, much like protein enzymes. These catalytic RNA sequences are called ribozymes. The function of a ribozyme depends upon the primary sequence of the RNA which folds into a 3-D structure. How do different ribozyme sequences fold? You can search for ribozyme sequences using Entrez BLAST (NCBI, 2006). Then you can use a program like MFOLD () to submit your sequence for an analysis of its predicted 3-D structures based upon thermodynamics… Read more
