Finally, a worksheet that involves more than filling in some blanks. Your budding ecologists must graph and analyze three sets of data, then synthesize the information as they think about the impacts of plant reproduction on insects and what might cause a change in the time that plants begin to blossom. The questions and activities found here are at the top of Bloom's Taxonomy, which can be rare in a worksheet. Depending on the graphing abilities of your classes, this could take one or two class periods.
