The document describes an experiment to observe osmosis in eggs. Two eggs were placed in water and corn syrup to observe how they would change. The egg in corn syrup got smaller and heavier as water left the egg to equalize concentrations. Meanwhile, the egg in water got larger and lighter as water entered the egg to equalize concentrations between the higher water concentration outside and lower concentration inside. The experiment demonstrated how osmosis causes water to move across a membrane from high to low concentration areas.

2. To observe osmosis in a cell.
 1) Place egg in vinegar to
remove shell.
 2) Measure weight of egg using
balance.
 3) Measure weight using
measuring tape and string.

3.  4) Place 1 egg in water and
1 in corn syrup.
 5) Weigh and measure the
eggs again.

4.  1) Corn syrup

-Weight: Heavier
-Size: Bigger
-Looks: Different

10. Corn Syrup Egg
 Got smaller water left egg
 higher water concentration
then corn syrup egg
 Water moved from higher
concentration (egg) to lower
concentration (corn syrup)
Water egg
 Egg got larger water entered
egg
 Lower concentration then
water
 The water moved from higher
concentration (water) to low
concentration (egg)
