The student conducted an experiment to observe osmosis in eggs. Eggs were weighed and measured before being placed in water or corn syrup for 24 hours. As hypothesized, the egg in corn syrup absorbed water, increasing its weight and turning yellow-brown. However, its size decreased. Conversely, the egg in water lost water, gaining size but increasing in weight. The conclusions drawn matched the observations but not the original hypotheses.

2. Purpose
To observe osmosis in a cell.
 Place eggs in vinegar.
To remove the shell.
 Measure weight of
egg using a balance.
 Measure the size of
egg using a
measuring tape.
 Place the egg in
different solutions (
one in water, one in
corn syrup
 Weight and measure
the eggs again.

3. Hypothesis
 Egg in corn syrup
 Weigh a lot more
 Looks yellow
brownish
 Egg in water
 It’ll stay the same
 It might weigh less
 It’ll be moist/wet

4. Materials
 Eggs
 Beakers
 Balance
 String
 Measuring tape
 Vinegar
 Corn syrup
 Water

5. Observation Continuation
 1) Saw bubbles from
the egg and up.
 2) took the eggs out of
the vinegar it was
squishy/bouncy.
 3)the egg sat here for
24 hours, a lot of foam
appeared.
 4) egg sat in water for
24 hours it looked
fatter.
 5) sat in corn syrup for
24 hours it looked
demented and soggy.

6. Observation
Corn Syrup Corn Syrup
Before After
Weight: 71.5 Weight:50
Size: 16 cm Size
Water Water
Before After
Weight: 71.4 Weight: 87.59
Size 16 cm Size: 18.5 cm

7. Conclusion
 Water Egg
 Increased in size(because water moved
out of the egg)
 Water became higher concentration too
lower concentration.
I wasn’t right about my hypothesis
because I said it would decrease and it
would stay exactly the same.

8. Conclusion
 Corn Syrup Egg
 Decreased in size(because water moved
into the egg)
 Water became lower concentration too
higher concentration
I wasn’t right about my hypothesis because I
said it would increase, but the part I was right
about was how it turned yellowish brown.
