This document describes an experiment to observe osmosis in eggs. Two eggs were placed in water and corn syrup after measuring their initial weight and size. It was hypothesized that the egg in water would gain weight and stay the same size, while the corn syrup egg may change color but gain weight and stay the same size. After observing the eggs, it was found that the water egg gained weight and size as water moved into it, while the corn syrup egg lost weight and size as water moved out of it due to differing concentrations. This demonstrated the principle of osmosis.

2. Purpose.
 To observe osmosis in a
cell.
 Place eggs in vinegar to
remove shell.
 Measure weight of egg.
 Measure size of egg.
 Place one egg in water
and the other one in
corn syrup.
 Measure again

3. Hypothesis (Egg in Water)
 Egg will be heavier.
 The size would be the
same.
 The egg will look the
same.

4. Hypothesis (Corn Syrup Egg)
 The egg might change its
colour.
 Size would be the same.
 The egg might get
heavier cause of the corn
syrup.

5. Materials
 Eggs
 Beakers
 Balance
 String
 Measuring tape
 Vinegar
 Corn syrup
 Water

6. Observations
Observations Before After
• Corn Syrup • W 71.5g • W 50.6g
• S 16cm • S 14.6 cm
• Water • 71.4g • 87.5g
• 16cm • 18.5cm

7. Observations After Vinegar
 Bouncy
 Squishy
 Bubbles in the beaker

8. Observation After Syrup
 Dented
 Inflated
 Brown colour

9. Observation After Water
 The egg got fatter.
 Same colour.
 Higher concentration to
lower concentration.

10. Conclusion (Water Egg)
 Water moved into the
water egg.
 The egg had a lower
concentration.
 Water moved from
higher concentration to
lower concentration.

11. Conclusion (Corn Syrup Egg)
 The egg got smaller.
 Water moved out of the
egg.
 The water moved from
higher concentration to
lower concentration.
 This is osmosis.
