Integrated Foundations and Pre-Calculus Project

I'm mulling over ideas for projects for Foundations and Pre-Calculus 10 Projects. FPC10 seems like the perfect place to do some 2 variable linear regressions. Students could measure age vs. height or age vs. mass or age vs. almost any physical characteristic to create scatter plots and make lines of best fit. This integrates quite a few curricular concepts and involves kids in the school.
