This a great Biology lab to use when you are teaching about cellular transport. Students will see that some substances can pass across the membrane and other substances cannot. This is one of my favorite labs, and my students always enjoy it.
Materials needed are: Dialysis Tubing, String, Glucose Solution, Glucose Test Strips, Beakers, Starch Solution, Iodine
Your download will include student handouts that are ready to be copied and passed out to your students. Each will include: Title, Introduction, Purpose, Procedure, Student Data Pages, Answers, and Teacher Preparation Notes.
I have included an editable Word document and a pdf copy of the lab.

I order it each year along with the rest of the lab supplies for my school. I have ordered from Carolina Biological, Flinn Scientific, Wards. I do not know of where it might be purchased locally, though. If you don't have time to order some, try plastic sandwich bags. They will work just fine. You just have to make sure that they are tightly sealed. The sandwich bags are kind of fun....the students realize that their sandwich is not really sealed up!!
