1. Egg Osmosis Experiment
By Lance Tugade
Room 8-73

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

3. Hypothesis
 Corn Syrup
 I think it will weigh
more
 The size will be
bigger
 It will look a jelly like
oval.
 Water
 I think it will weigh
less
 The size will be
smaller
 Will look like a
smaller egg

4. Materials
1) Eggs
2) Beakers
3) Balance
4) String
5) Measuring tape
6) Vinegar
7) Corn syrup
8) Water

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

6. Observation #2
 Egg bubbled up
 Shell gone became
squishy
 After 24 hrs beaker
became foamy
 After the egg sat in
water it got fatter
 After egg sat in corn
syrup egg deflated

7. Conclusion (Egg in Water)
 Got Larger
 Water moved in egg
 Higher Concentration
(water) to Lower
Concentration (egg)

8. Conclusion (Egg in Corn
Syrup)
 Got Smaller
 Water moved out of egg
 Higher Concentration
(egg) to Lower
Concentration (corn
syrup)

9. Conclusion (Hypothesis)
 Egg in Water
 Wrong
 Thought it would be
smaller and weigh less
and look like a smaller
egg
 Egg in Corn Syrup
 Partly Correct
 Thought it would be
bigger
and weigh less
 The only thing was right
was that it looked jelly
like
