This document describes an experiment to observe osmosis in eggs. Students removed the shell from eggs and measured their initial weight and size. One egg was placed in corn syrup and one in water for 24 hours. The egg in corn syrup shrank and became lighter due to water leaving the egg. The egg in water absorbed water, becoming larger and heavier.

2.  To observe in a cell
 Steps:
1. Place egg in vinegar to
remove the shell
2. Measure weight of the
egg using a balance
3. Measure the size of the
egg using string and
measuring tape
4. Place one egg in corn
syrup, place the other
egg on water

3.  Egg

5.  There’s bubble rising in the egg when it is on the
vinegar.
 There’s more bubble rising and the egg is trying to
float .
 Egg’s are still floating and at the top there’s a
foam .
 It’s no longer have a shell and its squishy .
 After sitting on corn syrup for 24 hours the egg
looks shrivelled up.
 After sitting on water for 24 hours the egg looks
large and it’s not floating.

6.  Water egg (Steve)
 Weight - I think it is
going to be lighter.
 Size – I think it is
going to be smaller.
 Look – I think it is
going to look the
same.

7.  Corn Syrup (Bob)
 Weight – I think its
going to be heavy.
 Size – I think its going
to be bigger.
 Looks – I think its
going to look the
same.

8.  Water egg become
larger .
 Water moved to the
egg.
 Water egg get heavier.
 Water egg looks the
same , nothing
happen.

9.  Corn syrup egg
become smaller.
 The water moved out
to the egg.
 Corn syrup egg
become lighter .
 Corn syrup egg looks
the same .

10.  Water Egg  Corn Syrup Egg
 WRONG  WRONG
 The size of the egg  The size of the egg
become larger become smaller
 The weight of the egg  The weight of the egg
got larger become lighter
 RIGHT  RIGHT
 The look of the egg  The look of the egg
didn’t change didn’t change
