1. EGG OSMOSIS
EXPERIMENT
Serena Tonnu
8-14

2. PURPOSE
 1) Place eggs in vinegar
 2) Measure the weight of egg
 3) Measure the size of the
egg using a measuring tape and
string

3. PURPOSE
 4) Place 1 egg in water and
the other in corn syrup
 5) Weigh and measure the
eggs again

4. HYPOTHESIS
 Corn syrup egg will weigh
more
 corm syrup egg will look sticky
 Corm syrup egg will look
brown
 Corn syrup egg will get bigger

5. HYPOTHESIS
 Water egg will weigh the same
 Water egg will be the same
size
 Water egg will look squishy
and soft

6. MATERIALS
Measuring tape String
Corn Syrup Balance
Vinegar
Water 2 Eggs 2 beakers

7. OBSERVATION
 1) bubbles coming out of egg
Corn Before After
 2) after 24hrs white foam is on top of
Syrup
Weigh- 64.9g Weigh- 35.3g the water
Size- 16.0 cm Size- 13 cm
 3) the skin is gone and feels soft, jelly
like
 4) eggs got larger from sitting in water
Water Weigh- 65.8g Weigh- 83.3g
Size- 16.5 cm Size- 18 cm for 2 days
 5) water egg got larger, syrup egg got
smaller

8. OBSERVATIONS
Egg after syrup (24hrs) Egg after vinegar Egg after water (24hrs)

9. CONCLUSION
 The water moved from the
higher concentration (egg) to
the lower concentration
(syrup)
 That’s why the corn syrup
egg got smaller (this is
osmosis)

10. CONCLUSION
 The water moved from the
higher concentration (water)
to the lower concentration
(egg)
 That’s why the water egg
got bigger (this is osmosis)

11. HYPOTHESIS (CORN SYRUP
EGG)
 Weight- wrong, because I
thought it would weigh more
 Size- wrong, because I
thought it would get bigger
 Looks- right, because I
thought it would look sticky
and brown

12. HYPOTHESIS (WATER EGG)
 Weight- wrong, because I
thought it would weigh more
 Size- wrong, because I
thought it would stay the same
size
 Looks- right, I thought it
would look squishy and soft
