1. EGG OSMOSIS
EXPERIMENT
By Anmarie Somar
8-16

2. PURPOSE
 To observe osmosis in a cell
 Place eggs in vinegar to remove the
shell
 Place egg in vinegar
 Measure the weight of the egg
using a balance
 Measure the size of the egg using
string and measuring tape
 Weight and measure the eggs again

3. HYPOTHESIS
Corn syrup egg Water egg
 Weight- I think that Bob will get  Weight- I think that Steve will be
smaller in weight more in weight
 Size- I think that Bob will get  Size- I think that Steve will be
smaller in size bigger in size
 Looks- I think it will look a little  Looks – I think that Steve will look
smaller like it’s bigger and like jelly.

4. MATERIALS
 2 Eggs
 Balance
 Measuring Tape & String
 Corn Syrup
 Water
 2 Beakers
 Vinegar

5. OBSERVATIONS
 1)There is bubbles rising to the top of
the egg
 2)More bubbles at the top and eggs
are floating
 3)Eggs are still floating and has foam
forming at the top

6. OBSERVATION
Before After
 4) After staying in corn syrup for 24
 hours , the egg looks shriveled up
Corn Syrup W: 67 g W: 44g
Egg
S: 16.1 cm S: 13.2 cm
Water W: 77.4 g W: 91.9 g  5) After sitting in water for 24
Egg hours the eggs have sunk and look
S: 16 cm S:17.5 cm
larger

7. CONCLUSION
 Water Egg
 Got larger
 Lower concentration
 Went from high concentration to low
concentration
 Syrup Egg
 Got smaller
 Water moved out of the egg
 Went from low to high concentration

8. CONCLUSION
 Water egg-
My hypothesis was correct for the water egg because..
I said the weight would be more. Also increased in size and it looked
bigger.
 Corn syrup egg-
My hypothesis was also correct for the corn syrup egg because…
I said the weight would be less. Also decreased in size and it size and it
looked smaller.
