I created this lab for my biology students. The lab uses dialysis tubing, starch, and Lugol's solution (iodine) to demonstrate diffusion. My students usually enjoy doing this lab.
I have also included a 2 page summary of the lab with tips on setting up the lab, conducting the lab, and sample student responses for the end-of-lab questions.
When you purchase this lab you will receive the 4 page lab and the 2 page teacher summary.
I use this lab when teaching the following Georgia Performance Standards:
SB1. Students will analyze the nature of the relationships between structures and functions in living cells.
a. Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane, in maintaining homeostasis and cell reproduction.
d. Explain the impact of water on life processes (i.e., osmosis, diffusion).
