The student conducted an experiment to observe osmosis in eggs placed in different solutions. Eggs were placed in corn syrup, water, and vinegar and their weights and sizes were measured before and after. The corn syrup egg got smaller and lighter as the egg's concentration was higher than the corn syrup. The water egg got larger and heavier as the water's concentration was higher than the egg. The purpose was to see how osmosis affected the eggs in different concentration solutions.

1. EGG OSMOSIS
EXPERIMENT
JM Joseph

2. Purpose
• Eggs in vinegar
• Measure weight of egg
with balance
• Measure size of egg
with string, measuring
tape

3. Purpose
• Place 1 egg in corn
syrup
• Place 1 egg in water
• Measure eggs again

4. Materials
• Eggs
• Balance
• Measuring Tape
• String
• Corn syrup
• Water
• 2 Beakers
• Vinegar

5. Hypothesis
• Corn syrup egg will be
heavier
• Size stays the same
• Will look like corn
syrup

6. Hypothesis
• Water egg will get
heavier
• Size will get smaller
• Looks will stay the
same

7. Observations
• Smaller Corn Syrup Egg
• Lighter Before 67g and 16.1cm
After 44g and 13.2cm
• Colour changed

8. Observations
Water Egg
• Larger Before 77.4g and
16.1cm
• Heavier
After 91.96g and
• Colour didn’t change 17.5cm

9. Conclusion
• Got larger, wrong
about size
• Got heavier, right
about the weight.
• Water got bigger, egg
low concentration and
water high
concentration

10. Conclusion
• Wrong about size
• Wrong about weight
• Corn syrup got smaller,
egg high concentration
and corn syrup low
concentration
