1. Egg Osmosis Experiment
JOANNA O. NALAM 8-73

2. Purpose
To observe osmosis in a
cell.
1. Place egg in vinegar to
remove shell.
2. Measure weight of egg
using a balance .
3. Measure size egg using
measuring tape.

3. Purpose
To observe osmosis in a
cell.
 To place one egg in water
 To place one egg in corn
syrup

4. Hypothesis
 Corn Syrup
Size: bigger
Weight: heavier
Looks like: bigger than the usual and slimy

5. Hypothesis
• Water
Size: the same
Weight: the same
Looks like: no difference

6. Materials
• Eggs
• Beaker
• Balance
• Measuring Tape
• String
• Vinegar
• Corn syrup
• water

7. Observations
Before After
Corn Syrup Weight : 71.5 g Weight: 50.6 g
Size: 16 cm Size: 14.5 cm
Water Weight: 71.4 g Size: 87.5 g
Size: 16 cm Size: 18.5 cm

8. Observations
 After 24 hrs. in vinegar:
egg shell disappeared, squishy and bouncy
 After 24 hrs. in corn syrup:
egg is dented and deflated
 After 24 hrs. in water:
egg got fatter

9. Observations
 Corn Syrup Egg  Water Egg
(after) (after)

10. Conclusion

11. Conclusion
 The corn syrup egg got smaller because water moved
out of the egg. This was due to the fact that the egg has a
higher water concentration than the corn syrup. The
water moved from higher concentration (egg) to lower
concentration (corn syrup).
 The water egg got bigger because water moved into the
egg. This was due to the fact that the egg had a lower
concentration of water. The water moved from higher
concentration (water) to lower concentration (egg).

12. Hypothesis Conclusion
 Water Egg  Corn syrup Egg
 Size  Size
- wrong - wrong
Egg got bigger did not remain the Egg did not bloat up instead inflated
same
 Weight
 Weight
- wrong
- wrong Egg did not get heavier but lighter
Egg got heavier not the same
