2. Purpose
To observe osmosis in a cell.
• 1) Place in egg in vinegar.
To remove the shell
• 2) Measure size of egg
using a balance
• 3) Measure size of using
measuring tape
• 4) Place one egg in water,
Place the other egg in corn
syrup
• 5) Weight and measure
eggs again
3. Hypothesis
Corn Syrup
• Weight is going to be weigh
less
• Size is going to smaller
• It’s going to look like the
same
Vinegar
• weight is going to be
less
• Size look same
• looks like an egg
4. Materials
• Eggs
• Beaker
• Balance
• String
• Measuring Type
• Vinegar
• Corn Syrup
• Water
5. Observations
• Bubbies coming from the egg.
• 24 hours in vinegar
• Egg sat in water 24hrs egg got fatter
BEFORE AFTER
Corn Syrup W 71.5 W 50.6
S 16cm S 14.5
Water W 71.5 W 87.5
(H2O)
S 18.5cm S 18.5cm
6. Conclusion
Water
• Got larger in water
• Water moved in egg
• Had lower concentration
• Water moved higher
Corn Syrup
• CS egg got smaller
• CS got in egg
• Higher concentration
7. Hypothesis
Correct
• size smaller
• weight less
• Appearances- egg same
Incorrect
• weigh same
• bigger egg
• Size the same
• Appearances-egg same
