The student conducted an experiment to observe osmosis in eggs by placing one egg in water and another in corn syrup. She hypothesized that the egg in corn syrup would gain weight and size while the egg in water would not change. Her observations found that the egg in water gained weight and size while the egg in corn syrup lost weight and size, contradicting her hypotheses.

1. EGG OSMOSIS By: Joy Abaya
EXPERIMENT 8-73

2. PURPOSE
To observe osmosis
in a cell.
1. Place the egg in vinegar.
To remove.
2. Measure weigh of egg
using a balance.
3. Measure size of egg
using measuring tape.
4. Place one egg in the
water, place the other
egg in the corn syrup.
5. Weigh and measure the
egg again.

3. HYPOTHESIS
Water: Corn Syrup:
 Weight- I think the weight  Weight- I think the weight
of the egg will not change. will not change.
 Size- I think the size will  Size- I think the size will
not change. add up.
 Look Likes- I think it will  Look Likes- I think it will
look the same. looked dif ferent.

4. MATERIALS
 Egg
 Beaker
 Balance
 String
 Measuring Tape
 Vinegar
 Corn Syrup
 Water.

5. OBSERVATIONS
Before After 1. After it sat 24 hours:
Vinegar:
Corn W- 71.5 W- 50.6 - The shell was gone
Syrup grams grams because of the vinegar.
S- 16 cm S- 14.5
Corn Syrup:
cm
-dented and deflated
Water W- 71.4 W- 87.5 Water:
grams grams -fatter.
S- 16 cm S- 18.5
cm

6. CONCLUSION
Water Egg:
-larger
-higher concentration(water).
-lower concentration(egg).
Corn Syrup Egg:
-smaller
-higher concentration(egg).
-lower concentration(corn syrup).

7. CONCLUSION
Corn Syrup Water
My hypothesis: My hypothesis:
Weight- Right because Weight- Wrong because
the weight change. the weight change.
Size- Wrong because the Size- Wrong because the
size didn’t add up. size change.
Looks like- Right because Looks like- Wrong
it look different. because it look different.
