1) The student conducted an experiment to observe osmosis using eggs placed in corn syrup and water. 2) She hypothesized that the corn syrup egg would weigh more and change color, while the water egg would weigh more but stay the same size. 3) Her observations found that the corn syrup egg lost weight and shrank, while the water egg gained weight and increased in size, partially supporting her hypotheses.

1. Egg Osmosis Experiment
Paige Blanca
8-17

2. Purpose
• 1) To observe osmosis in a cell
• 2) Place eggs in vinegar to
remove the shell
• 3) Measure the weight of the
eggs using a balance
• 4) Place 1 egg in corn syrup
and the other in water
• 5) Weigh and measure the
eggs again

3. Hypothesis
Corn Syrup Egg
• Weigh more because syrup is
going into it
• Get bigger or larger in size
• Change its colour to the colour
of the syrup

4. Hypothesis
Water Egg
• Weigh more because the water
is going into it
• The size will stay the same

5. Materials
Materials used:
• Eggs
• 2 beakers
• Corn syrup
• Vinegar
• Water
• Balance
• String
• Measuring tape

6. Observations
Before After
Corn Syrup
Egg
Weight: 71.3
Size: 17cm
Weight: 48.8
Size: 13cm
H20 (water) Weight: 62.2
Size: 14cm
Weight: 77.0
Size: 18.5

7. Observations
After Vinegar After syrup 24hrs After Water 24hrs
- Bubbles coming up
- Eggs at the bottom
- Squishy
- Floating
- Puffy
- Bubbles
- Floating

8. Conclusion
Water Egg-
• Water moved in, egg got larger
• Egg had lower water
concentration than the water
• The water moved from higher
(water) to lower concentration.
(corn syrup)

9. Conclusion
Corn Syrup Egg-
• Water moved out, egg got
smaller
• Egg had higher concentration
than corn syrup
• Water moved from higher
(egg) to lower concentration
(corn syrup)

10. Conclusion
Corn Syrup Egg
• Wrong about the size of the corn syrup egg
• Wrong about the weight of the corn syrup egg
• Right about the appearance of the corn syrup egg
Water Egg
• Wrong about the size of the water egg
• Right about the weight of the water egg
• Right about the appearance of the water egg
