2. PURPOSE
• To observe
osmosis in a cell.
• Steps:
1. Place 2 eggs
in vinegar (24
hrs)
Placing Egg in
2. Measure the
Vinegar weight of the
egg
3. PURPOSE
3. Measure the
size/circumferenc
e of the egg
4. Place 1 egg in
corn syrup, place
other in water.
(Leave for 24hrs)
5. Weigh and
measure the eggs
Egg Placed in
Corn Syrup
again.
4. HYPOTHESIS (CORN SYRUP EGG)
• Weight: It will
increase
• Size: Will also
increase
• Exterior
Appearance:
• Will be a lighter
shade of corn
syrup
5. HYPOTHESIS (WATER EGG)
• Weight: Increase
• Size: Increase
• Exterior
Appearance:
• Egg will look the
same
7. OBSERVATIONS – WEIGHT & SIZE
24 hrs Before 24 hrs After
Weight - 67 g Weight – 44 g
Corn Syrup
Egg Size – 16.1 cm Size – 13.2 g
Weight – 77.4 g Weight – 91.9 g
Water Egg
Size – 16 cm Size – 17.5 cm
8. OBSERVATIONS
• (Both eggs) After
Vinegar(24 hrs):
• Eggs were:
• Foams formed
on top
• Jell-O-like /
Squishy
Both Eggs After 24
hours in Vinegar
9. OBSERVATIONS
• After Water(24 hrs):
• Eggs were:
• Floating on top
• Larger
Water Egg
After 24 hours
• After Corn Syrup(24
hours):
• Eggs were:
• Floating on top
• Deflated
• Shrivelled
Corn Syrup Egg • Smaller
After 24 hours
10. CONCLUSION (WATER EGG)
• Egg increased in size
• Higher
Concentration(Water)
went to lower
concentration(Egg).
• Cells want to make
water concentration
equal on both the
High to Low Concentration water and the egg
11. CONCLUSION (CORN SYRUP
EGG)
• Egg decreased in
size:
• High concentration
goes to Low
concentration
• Corn syrup - low
concentration
• Egg - High
concentration
Water particles moved
out of the egg
High to Low Concentration
12. CONCLUSION – HYPOTHESIS
(WATER EGG)
• Weight:
• Correct. Weight
Increased
• Size:
• Correct. Size
Increased
• Appearance:
Water Egg • Correct. Did not
change
