This document describes an experiment to observe osmosis in eggs. Students placed eggs in vinegar, corn syrup, and water and measured changes. They found that the egg in corn syrup shrank and became puffy as the egg's liquid entered the lower concentrated corn syrup. Meanwhile, the egg in water absorbed the liquid and became larger and squishy as the water had a lower concentration than the egg. The experiment showed that osmosis causes liquids to move from higher to lower concentrated solutions across a membrane.

1. EGG OSMOSIS EXPERIMENT
By: Kim Gacusan

2. PURPOSE
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

3. HYPOTHESIS
We need to find the
weight, size, and look:
Corn Syrup Egg-
Heavier
Bigger
Liquid go into the egg

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

5. MATERIALS
You will need:
Egg
2 Beakers
Corn syrup
Vinegar ( Acid)

6. MATERIALS
Balance
String
Measuring Tape
Water

7. OBSERVATION
Corn Syrup Before After
W-71.3g W-48.8g
S- 17 cm S-13 cm
H2O W- 62.2g W-77.0g
S-14cm S-18.5cm

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

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

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