1. EGG DIFFUSION LAB

2. Title: Egg Diffusion Lab
Problem: What will happen to the mass and texture of an egg when placed in vinegar, corn syrup, and water?

3. Background: Include explanations/answers to the following topics in complete sentences. You also need to include one introductory statement and a conclusion sentence. This background should be in paragraph form, like an essay.
Define & explain diffusion and osmosis
Define & explain isotonic, hypertonic, and hypotonic
What determines whether or not diffusion occurs?
How is the membrane of an egg (inside the shell) similar to a cell membrane?

4. Hypothesis: Procedure:
If the egg is soaked in vinegar, then _______________
If the egg is soaked in corn syrup, then _____________
