Reviewer Comments:

In this investigation, students observe the movement of molecules though the cell membrane by using the very large cell membrane of a chicken egg. These are two different methods in this collection, one activity measuring the mass of two identical previously-submerged-in-vinegar eggs after they are placed in beakers of water and corn syrup, respectively and concurrently. Included is a graph of sample data. The second activity measures the circumference of the egg (and volume of the liquid) when a single egg is placed in vinegar, then corn syrup, then water over the course of nine days. This activity includes student lab handout, including a detailed procedure and space for a conclusion and post-lab questions.

I do this activity every year with 7th graders - what a great way for kids to really visualize osmosis. They can't wait to come in every morning and check…
