EGG DIFFUSION LAB DIRECTIONS 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 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? 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 Gain/Los (grams) s (grams) Raw Egg Egg after vinegar Egg after corn syrup Egg after water NO DATA Appearance Type of solution 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. 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
