The document describes an experiment to observe osmosis in eggs. Eggs are weighed and measured before being placed in either corn syrup or water for 24 hours. After removal, the eggs are weighed and measured again. The egg in corn syrup shrank in size and weight, while the egg in water gained size and weight, demonstrating that water moved into the egg in water but out of the egg in corn syrup due to differences in solute concentration between the solutions and egg.

2. To observe osmosis in a cell.
 Place eggs in vinegar to remove the shell.
 Measure weight of the egg using a balance.
 Measure the size of the eggs using string and
measuring tape.
 Place one egg in corn syrup, place the other egg in
water.
 Weigh and measure the eggs again.

3.  Eggs
 Balance
 measuring tape
and string
 corn syrup
 Water
 2 beakers
 vinegar

4. Corn Syrup Egg (bob)
 Weight, size, and looks
 Weight- I think the
weight will decrease.
 Size- I think it’s going to
be smaller.
 Looks- It will become
smaller.

5. Water Egg (steve)
 Weight, size, and
looks
 Weight- I think the
will increase.
 Size- I think it’s going
to be larger than the
original size.
 Looks- It will become
bigger.

7.  There are bubbles.
 There are more bubbles the
eggs are floating.
 The eggs are still floating and
foam floating on the top.
 It’s no longer have a shell and
it’s squishy.
 After sitting in Corn Syrup for
24 hrs. the egg looks
shrivelled up and smaller.
 After sitting in water for 24
hrs. the egg looks larger and
heavier.

8. Water Egg
 Water egg got larger because water
moved into the egg. Why?
This was due to the fact that the egg
had a lower concentration of water than
the water.
 The water moved from higher
concentration (water) to lower
concentration (egg).
 My Hypothesis in Water Egg is correct
in Size, Weight, and looks.

9. Corn Syrup Egg
 Corn syrup egg got smaller because
water moved out of the egg. Why?
This was due to the fact
that the egg had a higher
concentration of water.
 The water moved from higher
concentration (egg) to lower
concentration (corn syrup).
 My Hypothesis in Corn Syrup Egg is
correct in Size, Weight, and looks.
