Irena Tonnu 8-14
EGG OSMOSIS EXPERIMENT
To observe osmosis in a cell1) Place eggs in vinegar2) Measure the weight of
the egg
PURPOSE
3) Measure the size of the egg
4) Place one egg in water and one egg in corn syrup 5) Weigh and measure egg
PURPOSE
Corn Syrup Egg• The weight is going to be
lighter• The size is going to be
smaller• Its going to look a little
bit brown and yellow
HYPOTHESIS
Water Egg• The weight is going to be
heavier • The size is going to be
bigger• It’s going to look the
same
HYPOTHESIS
• Vinegar• Corn syrup• 2 eggs
MATERIALS
• Measuring tape and string
• Water• 2 beakers• Balance
MATERIALS
OBSERVATIONS
Corn Syrup Egg (After 48 hours)
Water Egg (After 48 hours)
Vinegar Egg (After 24 hours)
OBSERVATIONS
• 1) bubbles coming out of egg
• 2) after 24hrs white foam is on top of the water
• 3) the skin is gone and feels soft, jelly like
• 4) eggs got larger from sitting in water for 2 days
• 5) water egg got larger, syrup egg got smaller
Corn Syrup Egg• Egg got smaller• Water left egg
• Water moved from high to low concentration
(osmosis)
CONCLUSION
Water Egg• Water egg got larger• Water entered egg
• Water moved from high to low concentration
(osmosis)•
CONCLUSION
Corn Syrup Egg• Weight- right, I thought it
would weight more• Size- right, I though it
would be smaller• Looks- right, I thought it
would a bit yellow
CONCLUSION (HYPOTHESIS)
Water Egg• Weight- right, I thought it
would weigh more• Size- right, I thought it
would be larger• Looks- wrong, I thought it
would look the same
CONCLUSION (HYPOTHESIS)
