1. Ace Guinto

2. Purpose
 To observe osmosis in a
cell
 1) Place eggs in vinegar
to remove the shell.
 2) Measure the weight of
the eggs.
 3) Measure the size of
the eggs.

3. Purpose (2)
 4) Place 1 egg in corn
syrup and place other in
water.
 5) Weigh and measure
the eggs again.

4. Hypothesis
Corn Syrup Egg:
I think:
 Weight- less
 Size- stay the same
 Appearance- covered in
syrup

5. Hypothesis (2)
Water Egg:
 Weight- more
 Size- larger
 Appearance- wet

8. Observations (2)
 1) After 24 hours,
bubbles were appearing.
 2) The eggs are floating.
 3)Foam appeared on the
top.
 4) The eggs became
softer.

9. Observations (3)
 5) We put the corn syrup
egg into water.
 6) Then we put the other
egg into water as well.
 7) After a day, the CS egg
got smaller and weighed
less.
 8) The Water egg got
larger and weighed
more.

10. Conclusion
 Both eggs have an amount of
water in them.
 The egg in the water had
become larger.
 Since it had a lower
concentration than the water.
 The water moved from high
concentration to low
concentration.

11. Conclusion (2)
 The egg in the corn syrup had
become smaller.
 The egg had higher
concentration of water than
the corn syrup.
 So the water in the egg
moved from high
concentration (egg).
 To lower concentration (corn
syrup)
