Document Sample

```					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?
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:
   Table 1: Mass and appearance of egg after
soaking in various solutions
Mass   Gain/Los    Appearance       Type of

   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
 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.
