EGG OSMOSIS
1. Record the mass and circumference of each egg at day 1. (Measure the circumference
around the widest part, not lengthwise.)
2. Put each egg in a container labeled Egg 1 and Egg 2. Pour in enough vinegar to cover the
egg. Cover the container. Let it sit for at least 24 hours.
3. Observe your eggs at Day 2. Observe what happened to the egg shell at Day 2. What do you
think causes it?
4. Rinse and dry each egg and measure the mass or circumference of each egg. Record your
results for Day 2.
5. Empty the vinegar from the container for Egg 1 and rinse the container. Put Egg 1 back in
the container and add water to cover the egg. Ensure that the egg is fully submerged in the
water for at least 24 hours.
6. Empty the vinegar from the container for Egg 2 and rinse the container. Put Egg 2 back in
the container and add corn syrup to cover the egg. Ensure that the egg is fully submerged in
the corn syrup for at least 24 hours.
7. For Day 3, compare and contrast the appearance of the egg that has been in water vs. the
egg that has been in corn syrup.
8. Rinse the corn syrup off of Egg 2. Dry each egg, and measure and record the mass or
circumference for Day 3
