EGG OSMOSIS EXPERIMENT
By Gurpreet Singh 817
To observe osmosis in a cell.
1) Place eggs in vinegar to remove the shell
2) Measure the weight
3) Measure the size of the eggs
PURPOSE
4) Place one egg in corn syrup and place the other in water
5) Weigh and measure the egg again
PURPOSE
Weight, size and look weight heavier corn syrup make heavier why corn syrup is heavier
Size larger corn syrup particles go inside the egg
Look darker colour corn syrup is darker than egg
HYPOTHESIS CORN SYRUP
Weight, size, look
Weight increase water has more weight than egg
Size increase because water particles egg
Look same but soggier and squishy
HYPOTHESIS WATER
Egg (2)
Beakers (4)
Corn syrup
Vinegar
Water

MATERIALS
OBSERVATIONS
Corn syrup
W 71.3
S 17cm
W 48.8
S13
Water W 62.2
S 14
W 77.0
S 18.5
Before After
1. After vinegar
eggs are at bottom, some bubbles
2. After syrup
floating, more bubbles little foam
3. After water
More foam, squishy, soft, poufy
OBSERVATIONS
PA I N T D R A W I N G
Thought corn syrup get heavier but got lighter
Shrunk instead of get bigger
Looked the same colour as thought darker
CONCLUSION CORN SYRUP
Weight increased like thought
size increased by 4.5
Looked squishy
CONCLUSION WATER EGG
Corn syrup was wrong all
Weight WrongSize Wrong Appearance wrong
HYPOTHESIS CORRECTION
Water was correct 3 of them
Weight Right Size RightAppearance Right
