Here is a simple project. Administer IQ tests to a group of children upon entry to school (or maybe one year later). Correlate those IQ scores to academic achievement each following year. If you find that the IQ of 5-year-olds predicts many future outcomes, that will be a badly needed reminder that schools CANNOT make everyone good students.
