I am still on the fence about the food cell, to be honest, but it was fun teaching her about gelatin and showing her how to make it, and it was kind of cool to see her working out different things to represent other cell parts. Constructivism is big in education these days, for better or for worse (works great in a http://customwritingcompany.com/
Montessori setting, a mixed bag outside it), and there are certainly worse ways for kids to demonstrate what they know about cells - especially if they're limited to 2-dimensional worksheets and fact-regurgitation for the sake of saving time. I would have felt differently about it had I been a parent working multiple jobs, though (less able to help at home), and definitely not been thrilled about it as a high school assignment, but in 6th grade? That was part of elementary school in our district until relatively recently.
