This document describes an experiment to observe osmosis in eggs. Students placed eggs in vinegar to remove the shells, then measured and weighed them. One egg was placed in water and one in corn syrup. After 24 hours, the egg in water gained weight and maintained its size, while the egg in corn syrup lost weight and shrank, supporting the hypothesis that osmosis would cause water to move into the egg in water but out of the egg in the higher concentrated corn syrup.

1. Egg osmosis experiment
Shari Harper 8-73

2. Purpose
To observe osmosis in a cell.
• 1) Place in egg in vinegar.
To remove the shell
• 2) Measure size of egg
using a balance
• 3) Measure size of using
measuring tape
• 4) Place one egg in water,
Place the other egg in corn
syrup
• 5) Weight and measure
eggs again

3. Hypothesis
Corn Syrup
• Weight is going to be weigh
less
• Size is going to smaller
• It’s going to look like the
same
Vinegar
• weight is going to be
less
• Size look same
• looks like an egg

4. Materials
• Eggs
• Beaker
• Balance
• String
• Measuring Type
• Vinegar
• Corn Syrup
• Water

5. Observations
• Bubbies coming from the egg.
• 24 hours in vinegar
• Egg sat in water 24hrs egg got fatter
BEFORE AFTER
Corn Syrup W 71.5 W 50.6
S 16cm S 14.5
Water W 71.5 W 87.5
(H2O)
S 18.5cm S 18.5cm

6. Conclusion
Water
• Got larger in water
• Water moved in egg
• Had lower concentration
• Water moved higher
Corn Syrup
• CS egg got smaller
• CS got in egg
• Higher concentration

7. Hypothesis
Correct
• size smaller
• weight less
• Appearances- egg same
Incorrect
• weigh same
• bigger egg
• Size the same
• Appearances-egg same
