2. Purpose
To observe osmosis in a
cell
place eggs in vinegar
to help remove the
shell
Measure the weight of
the egg using a
balance
Measure the size of the
egg using a measuring
tape and string
3. Purpose
Place one egg in
water
Place the other in
corn syrup
Weigh and
measure the eggs
again
4. Hypothesis
Corn syrup egg-
weight, size, looks
The weight of the
egg will get heavier
The size will be the
same
The look of the egg
would be a light
brown
5. Hypothesis
Water egg-
weight, size, looks
The
size, weight, and
looks of the water
egg will be the
same
7. Observations
bubbles coming off
Before After egg
Corn syrup W-64.9g W-35.3g
Egg S-16.0cm S-13.0cm Skin is gone and eggs
are jelly like
Water egg W-64.9g W-83.3g
S-16.5cm S-18.78g
8. Observations
corn syrup egg is
soft, soggy and
brownish
water egg is larger
and transparent
9. Conclusion
Corn syrup egg got
smaller
Egg had higher
water
concentration
Water moved from
high to low
concentration
10. Conclusion
Water egg got
larger
Egg had lower
water
concentration
Water moved from
high to low
concentration
11. Conclusion
Hypothesis about
water egg’s weight
, size, and look was
wrong
Hypothesis about
corn syrup egg’s
weight and size was
wrong
Corn syrup
hypothesis about
look was right
