This document describes an experiment on egg osmosis. The purpose is to observe osmosis in eggs by placing one in corn syrup and one in water, then measuring changes in weight and size. The hypothesis is that the corn syrup egg will stay the same and the water egg will stay the same. Observations show the corn syrup egg increased dramatically in size while the water egg increased slightly. The conclusion is that water moved into the corn syrup egg by osmosis due to higher water concentration outside, and the hypothesis was wrong about changes.

1. Egg Osmosis
Experiment
Jenny Reposar 8-16

2. Purpose
 To observe osmosis in a cell
 1. Place 2 eggs into
vinegar to remove shells
 2. Measure weight of the
egg using balance
 3. measure the size of the
eggs using string and
measuring tape
 4. Place 1 egg in corn syrup.
Place the other egg in
water
 5. weight and measure the
eggs again

3. Hypothesis
I think that the corn
syrup egg will
weight, size and
look, stay the same
 I think the water egg
will weight, size and
look, stay the same

4. Materials
 Eggs
 Balance
 Measuring tape and
string
 Corn syrup
 Water
 Two beakers
 Vinegar

5. Observations
 1. Bubbles are rising up
 2. More bubbles at the
top and floating
Before After  3. Still floating, the foam is
starting to foam
Corn W. 67g W. 44
Syrup S. 16.1 cm S. 132 cm  4. It is no longer has a
shell, it’s squishy
Water W. 77.4 g W. 91.1 g
S. 16 cm S. 17.5cm  5. After sitting in the corn
syrup for 24 hours. The
egg looks like it’s shriveled
up
 6. After sitting in the water
for 24 hours the egg sunk
and looked larger

6. Conclusion
 Corn syrup egg got larger
because the water
moved into the egg
 This was due to the fact
that the egg had a
higher concentration of
water
 The water moved from
higher concentration
(water) to lower
concentration (egg)

7. Conclusion
 The part I got wrong
was when the egg
was on the water
and I thought it
would get larger.
 The part I got wrong
was when the egg in
the corn syrup would
get smaller.
