Procedure:
Day 1
Day 2
Day 3
Data (observations):
Qualitative Observations
Draw what the eggs looked like day 1 through day 3
Day 1
Egg 1
Egg 2
Day 2
Day 3
Conclusion (Analysis):
1. In your hypothesis, you were asked to predict what would happen to each egg in the experiment. How
did your results compare with your prediction?
2. After 24 hours, did Egg #1 contain more, less, or the same amount of water as it did before the
experiment? What is your evidence? After 24 hours, did Egg #2 contain more, less, or the same amount
of water as it did before the experiment? What is your evidence? (USE DAY 3’s results)
3. Use the terms concentration, osmosis, diffusion to explain why water moved into one egg
and out of the other.
4. What would happen if you left the eggs in water and syrup for a longer period of time (another day, for
example)? Is it possible to return the eggs to their original state before placing them into distilled
water or corn syrup?
5. What would happen if you placed the egg originally in corn syrup (Egg #2) into distilled water? Could
you restore the egg to its original state?
6. What would happen if you placed the egg originally in water (Egg #1) into syrup? Would it shrink?
