Egg Osmosis Experiment
To observe osmosis in a cell
• Place egg in vinegar (to remove the shell)
• Measure weight of egg using balance
• Measure size of egg using measuring tape
PURPOSE
To observe osmosis in a cell
PURPOSE
• Place another egg in corn syrup• Place one egg in water
Corn Syrup Egg:
Size: Smaller
Weight: Lighter
Looks like: Weakened Surface (white part, not
shell)
HYPOTHESIS
HYPOTHESIS
Water Egg:
Size: Larger
Weight: Heavier
Looks like: Stronger surface
MATERIALS
Balance String
Vinegar Water
Eggs
Measuring Tape
Beakers
Corn Syrup
OBSERVATION
Before AfterWeight: 71.5g
Weight: 50.6g

Weight: 71.4g

Corn Syrup
Water
OBSERVATION
After Vinegar:
Eggshell disappeared
Egg= squishy, bouncy
After corn syrup 24hrs:
Egg= dented, deflated
After water 24hrs:
Egg= Fatter
CONCLUSION
Water Egg
Water moved into egg, due to egg having a lower concentration
than water
water enters egg = egg got larger
Water moved from high concentration (water) to low concentration (egg)
CONCLUSION
Corn Syrup Egg
Water moved out of egg, due to egg having higher concentration than corn
syrup
Water (from egg) enters corn syrup= egg got
smaller
Water moved from high concentration (egg) to low concentration (corn syrup)
CONCLUSION
Hypothesis ConclusionCorn Syrup size- incorrect Corn Syrup weight-
correct
Was not smaller than predicted it Weighs lighter, than original stayed equal, proof: proof:
proof:
__________________________________________________________
Corn Syrup looks like- correct• Egg = weaker surface
than original
Time Before After

Before After
CONCLUSION
Hypothesis ConclusionWater size- correct Water weight- correct
• Larger than original size, Heavier than original weight, proof: proof:
__________________________________________________________
Water looks like- incorrect • Egg looked fatter
• Did not look like surface got
tougher
