The document describes an experiment to observe osmosis in eggs. Eggs were placed in corn syrup and water, and their weights and sizes were measured before and after. The egg in corn syrup got lighter and smaller as water moved out of it into the higher concentrated corn syrup. Meanwhile, the egg in water got heavier and larger as water moved into it from the lower concentrated water. This demonstrated the principles of osmosis and diffusion of water across a semi-permeable membrane.

2.  To observe osmosis in
a cell
 Place egg in vinegar to
remove the shell
 Measure the weight of
the egg

3.  Measure the size of
the egg
 Place one egg in corn
syrup and other in
water
 weigh and measure
the egg again

4.  Corn syrup egg-
weight will be heavier
and size will be the
same
 Water egg- Weight,
size, and look will be
the same

5.  Eggs
 2 Beakers
 Corn Syrup
 Vinegar

6.  Water
 Balance
 Measuring tape
 String

8.  1) -Eggs are at the
bottom
-bubbles are going
up from the egg
 2) -They are floating
and
more bubbles
 3) -More bubbles and
foam at the top

10. Corn Syrup Egg
 Egg got
lighter/smaller
 Water moved out of
the egg

11. Water Egg
 Water egg got larger
 Egg had lower
concentration
 Higher to lower
concentration
 Egg got
heavier/bigger
