A great lab for your cell biology unit, this lab uses common food items and kitchen materials to examine the behavior of cells in hypotonic, isotonic, and hypertonic solutions. There is likely more here than you can finish....They are all good activities and adapt well for demos. This lab is adapted, modified, and condensed from many old classics and simplified to easy-to-follow steps, Lab contains the following activities:
SECTION 1: Surface Area to Volume Ratio in Agar Cubes
SECTION 2: Classic Osmosis Exercises: Egg-cellent Osmosis & Selective Permeability
SECTION 3: Osmosis in Vegetable Cores
SECTION 4: Microscopy of Elodea Weed in Hypotonic & Hypertonic Solution
This lab can also be purchased in CAMP'S BIOLOGY BY THE NUMBERS: Lab Series 3 CELL BIOLOGY (available for release in September).
