To observe osmosis in a cell.
1.) Place egg in vinegar
2.) Measure the egg.
3.) Measure the size of the egg
4.) Place one egg in a beaker
5.) Weigh and measure the eggs again
PURPOSE
![Page 3: Kim's egg osmosis 817](https://reader035.vdocuments.mx/reader035/viewer/2022062401/58f02bfc1a28ab21248b4637/html5/thumbnails/3.jpg)
We need to find the weight, size, and look:
Corn Syrup Egg-
Heavier
Bigger
Liquid go into the egg

Water Egg-
Lighter than the regular weight
Size will stay the same
It will look the same

OBSERVATION
After vinegar… After syrup 24hrs…
After water 24hrs…
• They have bubbles
• The egg is sitting on the bottom
• Egg is floating
• More bubbles
• There are foam
• Egg became squishy and soft
• Egg in corn syrup was shrivelled and puffy

CONCLUSION
Water Egg
• It got larger• Egg has lower
concentration• The liquid went to
the eggCorn syrup
• It got smaller• The corn syrup
has lower • Concentration• The egg liquid
went to the corn syrup

My hypothesis is wrong• Opposite of what the
outcome
CONCLUSION
The Corn SyrupThe Water
• Smaller • Harder
• Bigger• Harde
r
But I was wrong… What happened is the opposite..The Corn Syrup The Water
• Smaller
• Soft
• Smaller• Soft
