EGG OSMOSIS EXPERIMENT
To observe osmosis in a cell
Place egg in vinegar to remove shell
Measure weight of egg using a balance
PURPOSE
Measure size of egg using measuring tape
One egg in water, other egg in corn syrup
Weigh and measure the eggs again
PURPOSE
Egg in CORN SYRUP: (weight, size, look like)
Weigh, more
Size, much more
Look, jelly
HYPOTHESIS
Egg in WATER: (weight, size, look
like)
Weigh, much less
Size, smaller
Look, jelly with plastic cover

MATERIALS
Before AfterCorn syrup Weight:
71.5 grams
Weight: 50.6 grams
Size: 16 centimetres
Size: 14.5 centimetres
Water Weight : 71.4 grams
Weight: 87.5 grams
Size: 16 centimetres
Size: 18.5 centimetres
OBSERVATIONS
After egg sat in vinegar for 24 hours:
Large amount of foam appeared
No shellBecame squishy
and bouncy
OBSERVATIONS
Water particles are small
Water went in the egg
Corn syrup particles are big
Water went out of the egg
OBSERVATIONS
After egg sat in corn syrup for 24 hours:
Looked dented DeflatedSmallerCover is thinner
OBSERVATIONS
Egg in Water Egg in Corn Syrup
CONCLUSION
The egg in the water got larger because:
Water moved into the egg
Egg had lower concentration of water
Water moved higher concentration (water) to lower concentration (egg)
CONCLUSION
The egg in corn syrup got smaller because:
Water moved out of the egg
Egg had higher concentration of water
Water moved from higher concentration (egg) to lower concentration (corn syrup)
CONCLUSION
My hypothesis is incorrect because:
Water EggWeight- wrongSize- wrongAppearance- wrong
Corn Syrup EggWeight- wrongSize- wrongAppearance- wrong
CONCLUSION
