1. EGG OSMOSIS EXPERIMENT
Charisse Ahmad 8-17

2. PURPOSE
 To observe osmosis in a
cell
 1) Place eggs in vinegar
to remove shell
 2) Measure weight of egg
 3) Measure size of egg
 4) Place one egg in corn
syrup, other egg in water.
 5) Weigh and measure
eggs again

3. HYPOTHESIS CORN SYRUP EGG
 Corn Syrup Egg
 Size will not change
 Weight will stay the
same
 Egg will look soggy and
sticky

4. HYPOTHESIS WATER EGG
 Water Egg
 Weight would be
heavier.
 Size would be bigger
 Egg will look fragile
and soggy

5. MATERIALS
 Eggs
 Beakers
 Corn syrup
 Vinegar
 Balance
 Water
 String
 Measuring tape

6. OBSERVATIONS
Before After
Corn Syrup W- 71.3 W- 48.8
S- 17 cm S- 13 cm
H2o W- 62.2 W- 77.0
S- 14 cm S- 18.5 cm

7. OBSERVATIONS (CONTINUE)
 (after vinegar) Eggs at
the bottom.
 Bubbles from eggs float
to top.
 (after syrup 24 hours)
Floating, more bubbles,
and a bit of foam at the
top
 (after water 24 hours)
More bubbles and foam
 24 hours later, turned soft
and squishy.
 Corn syrup egg =
shrivelled water egg =
puffy

8. CONCLUSION OF WATER EGG
 Got larger
 Water moved into egg
 Egg had lower
concentration, water
had high concentration
 Egg moved for lower to
higher.

9. CONCLUSION OF CORN SYRUP EGG
 Got smaller
 Water moved out
 Egg had higher
concentration, syrup
had lower.
 Water moved from
higher (egg) to lower
concentration

10. HYPOTHESIS
 Corn syrup egg after
experiment:
 Hypothesis was wrong
 Got smaller by size and weight
 Thought egg would stay same
 Egg shrunk
 Water in egg came out into corn
syrup to balance water in and out
of egg
 Water egg after experiment
 Hypothesis was correct
 Egg got bigger and weight
 Water entered egg because low
concentration
