EGG DIFFUSION LAB

Title: Egg Diffusion Lab Problem: What will happen to the mass and

texture of an egg when placed in vinegar, corn syrup, and water?

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?

Hypothesis: If the egg is soaked in vinegar, then _______________ If the egg is soaked in corn syrup, then

_____________ If the egg is soaked in water, then _________________

Procedure: Materials List: egg, beaker, balance, vinegar,

corn syrup, water

Instructions: Write and number the steps taken to complete the experiment.

Variables: Identify the independent variable: _______________________ Identify the dependent variable: ________________________

DATA:

Graph 1: Create one graph to depict your data Line or bar graph, label x and y axis, title the

graph

Discussion: Describe your data chart and graph. Using the

data, describe and explain the changes that occurred in the egg at each step. Use actual numbers to back up your findings. Reference your graph.

Discuss 2 possible sources of error within the procedure used and 2 possible effects of those errors on the outcome of the lab.

Conclusion: Restate the purpose. Summarize the results of the experiment. Explain if the data supported your hypothesis or

not. Explain if the results make sense based on your

background knowledge. Describe modifications your could make to this

experiment to further investigate the problem
