EGG OSMOSIS EXPERIMENT
PURPOSE
• To observe osmosis
in a cell.
• Steps:
1. Place 2 eggs in
vinegar (leave
for 24 hrs)
2. Measure the
weight of the
eggs
Placing Egg in
Vinegar
PURPOSE
3. Measure the size/circumference of the eggs
4. Place 1 egg in corn syrup, place other in water. (Leave for 24hrs)
5. Weigh and measure the eggs again.Egg Placed in
Corn Syrup
HYPOTHESIS (WATER EGG)
• Weight:
Increase
• Size: Increase
• Exterior
Appearance:
• Egg will look
the same
HYPOTHESIS (CORN SYRUP EGG)
• Weight: Increase
• Size: Increase
• Exterior
Appearance:
• Will be a lighter
shade of corn
syrup
MATERIALS
2 Eggs
Balance
Measuring
Tape
Water
Corn Syrup
Vinegar
2 Beakers

OBSERVATIONS
• (Both eggs) After
24 hrs in vinegar:
• Eggs were:
• Foams formed
on top
• Jell-O-like /
Squishy
Egg in vinegar after
24 hours
OBSERVATIONS
• After 24 hrs in Water:• Eggs were:
• Floating on top
• Larger
• After 24 hrs in Corn Syrup:• Eggs were:

• Deflated
• Shrivelled
• Smaller

After 24 hours
CONCLUSION (WATER EGG)
• Water Egg increased in
size/weight
• High concentration goes
to Low concentration
• Water - high
concentration
• Egg – low concentration
• water concentration
equal on both the water
and the egg must be
equalHigh to Low Concentration
(Water particles moved into
the egg.)
CONCLUSION (CORN SYRUP EGG)
• Egg decreased in size/weight:• High concentration
goes to Low concentration
• Corn syrup - low concentration
• Egg - High concentration
• water concentration equal on both the water and the egg must be equal
High to Low Concentration
(Water particles moved out
of the egg.)
