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.
