The document summarizes an experiment to observe osmosis in eggs placed in different solutions. Two eggs were weighed and measured, then one was placed in corn syrup and the other in water. After 24 hours, the eggs were weighed and measured again. As hypothesized, the egg in corn syrup got bigger and heavier due to gaining water, while the egg in water got puffier and lighter from losing material. The experiment showed how osmosis causes water to move from areas of lower to higher solute concentration across a semi-permeable membrane.

2. Purpose
- To observe osmosis in a cell
Place egg in vinegar to
remove shell
Measure the weight of
the egg
Place one egg in corn
syrup and place the other
in water
Weigh and measure the
eggs again

3. Hypothesis
Water egg
Water egg will be saggy
The weight would be
exactly the same
The size will be exactly
the same

4. Hypothesis
Corn syrup egg
The egg would get more
bigger
The egg would be more
heavy
It would be sticky and
bigger

5. Materials
Materials used
Eggs
2 beakers
Corn syrup
Vinegar
Water
Balance
String and measuring tape

6. Observations
Before: After:
Weight: 62.2 Weight: 77.0
water Size: 14 Size: 18.5
(H2o)
Weight. 71.3 Weight: 48.8
Corn Size: 17cm Size: 13
Syrup

7. Observations
After vinegar After syrup After Water
24hrs 24hrs
• Bubbles coming up • Squishy • Puffy
• Eggs on the bottom • floating • Bubbles
• Floating

8. Conclusion
Water egg
Water moved in to the egg
Egg had lower
concentration
Water moved from higher
to lower concentration
My hypothesis was wrong because I
thought the egg would stay exactly the
same in size appearance and weight.

9. Conclusion
Corn Syrup Egg
Corn syrup egg got smaller
Water moved out of the egg
Egg had higher
concentration
Water moved from higher
to lower concentration
My hypothesis was right because I said the
egg would get smaller. I also thought the
egg would get heavier but I was wrong.
