I have done various versions of a similar lab for years, and always have had trouble with getting students to really understand hypertonic, hypotonic, and isotonic solutions. I did the potato core lab as written in the modeling curriculum, had the kids graph the %change, and they were able to walk themselves through the analysis of the graph!!!!! I had always talked about the % change but had never had them graph it…that was the key.
