  • 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 diffusion and osmosis
  • Define isotonic, hypertonic, and hypotonic
  • What determines whether or not diffusion occurs?
  • What is osmotic pressure?
  • How is the shell of an egg similar to a cell
    membrane?

4
  • 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 List materials used
  • Instructions Write and number the steps taken
    to complete the experiment.
  • Variables
  • Identify the independent variable
    _______________________
  • Identify the dependent variable
    ________________________

DATA
  • Table 1 Mass and appearance of egg after soaking
    in various solutions

Mass (grams) Gain/Loss (grams) Appearance Type of solution
Raw Egg NO DATA
Egg after vinegar
Egg after corn syrup
Egg after water

  • Graph 1 Create one graph to depict your data
  • 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.
  • Discuss 2 possible sources of error within the
    procedure used and 2 possible effects of those
    errors on the outcome of the lab.

7
  • 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
