2. Purpose
 To observe osmosis in a
cell.
 Put egg in vinegar
 Measure weight of egg
 Measure size of egg

3. Purpose 2
 Put one egg in water
 Put other egg in corn
syrup
 Weight and measure
both eggs

4. Hypothesis
 Water Egg : It will get
larger
 It will be heavier
 Corn Syrup egg : It will
get bigger
 It will be heavier

5. Materials
 Vinegar
 Water
 Corn syrup
 String
 2 eggs
 Measuring tape
 Balance
 2 beakers

6. Observations
Before: After:
W- 64.9 g. W- 35.3 g.
Corn Syrup S- 16.0 cm S- 13.0 cm
Egg
Before: After:
Water egg W- 65.8 g. W- 83.3 g.
S- 16.5 cm S- 18 cm

7. Observations
 1. bubbles come up from
the egg
 2. eggs are now
floating, there is white
foam (after 2 hours)
 3. after 24 hours shell is
soft, jelly like, and
squishy
 4. corn syrup egg looks
soft after 2 days, soggy
and brownish.

8. Conclusion : Water Egg
~ Water Egg : Larger
~ Water : Higher
~ Egg : Lower
~ Water goes from high to
low
SIZE = right
WEIGHT = right
LOOKS = right

9. Conclusion : Corn Syrup Egg
 Corn Syrup Egg : Smaller
 Corn Syrup : Low
 Egg : High
 Goes high to low
 SIZE = wrong
 WEIGHT = wrong
 LOOK = right
