The student conducted an experiment to observe osmosis in eggs. Eggs were weighed and measured before being placed in water or corn syrup for 24 hours. As hypothesized, the egg in corn syrup became lighter and smaller as water moved out. However, the water egg became bigger as water moved in, making it heavier, which was unexpected. The purpose was to demonstrate osmosis and the results supported the definition and process of osmosis.

1. Egg Osmosis Experiment
 By Nathan Warkentin

2. Purpose
 The purpose is to observe
osmosis in a cell.
 1. Place eggs in vinegar to
remove shell.
 2. Measure weight of egg with
balance.
 3. Measure size of egg with
measuring tape.
 4.Place one egg in water and the
other in corn syrup.
 5. Weigh and measure the eggs
again.

3. Hypothesis
Corn syrup:
 Size-bigger
 Weight-heavier
 Look Like-A different colour
Water:
 Size-Same size as before
 Weight-Heavier
 Look Like-The same

4. Materials
 2 Eggs
 2 Beakers
 1 Balance
 String

5. Materials
 Corn Syrup
 Water
 Measuring tape

6. Observations Before After
 After the egg went in vinegar
the egg was bouncy and squishy.
 The top of the water was foamy.
Corn Syrup Weight Weight
 The shell came off.
71.5 50.6
 After the egg was in water for 24 Size Size
hours it was bigger. 16 cm 14.5 cm
 After the egg sat in corn syrup
for 24 hours it looked deflated. Water Weight Weight
71.4 87.5
Size Size
16 cm 18.5 cm

7. Conclusion
Water:
 Water egg got larger because
water moved into the egg.
 Due to the fact that egg had
lower concentration than water.
Hypothesis:
 My hypothesis was right, it was
heavy.
 My size and look were both
wrong, I thought it would be
same size.
 But it was bigger.

8. Conclusion
Corn syrup:
 Water move out of corn syrup egg.
 Corn syrup egg got smaller.
 The water moved from higher
concentration to lower.
 This is osmosis.
Hypothesis:
 I said it would be heavier and
bigger
 But it was lighter and smaller.
 I said it would look different and it
did
 It was more yellow and it was
deflated.
