1. Egg Osmosis
Experiment
Kamille Nevado 8-17

2. Purpose
 To observe osmosis in
a cell.
 Put eggs in vinegar
(remove shell)
 Weigh the egg (use a
balance)
 Measure the size
(use a tape or string)

3. Purpose
 Put one egg in
water and another
in corn syrup.
 Weigh and
measure again

4. Hypothesis
 Corn syrup egg:
weight, size and
look.
 Heavier
 Water is absorbed by
egg
 Size is the same
 Egg won’t get bigger.

5. Hypothesis
 Water egg: weight,
size and look.
 Will get heavier
 Water was absorbed
by the egg
 Size will get bigger

6. Materials
Eggs Beaker Corn syrup
Vinegar
Balance String

Tape Measure Water

7. Observation
Before After
Corn Syrup W: 71.3
S: 17 cm
W: 48.8
S: 13 cm
H2O (Water) W: 62.2
S: 14 cm
W: 77.0
S: 18.5 cm
- Bubbles coming up from the bottom
- The egg was soft after
- Egg was squishy
- Bubbles and foam showed up
- Squishy and soft
- Foam at top of egg

8. Conclusion: Water egg
• Water egg got larger
• Water moved into the egg.
• The egg had a lower water
• The water moved from higher concentration
(water) to lower concentration (egg).

9. Conclusion: Corn Syrup
• Corn syrup egg got smaller
• Water moved of the egg
• The egg had a higher concentration
• It moved from high concentration to low.

10. Conclusion: Hypothesis
Corn Syrup Egg:
• Size: Wrong- size got smaller
• Weight: Wrong- it got lighter
• Appearance: Right.
Water egg
• Size: Right- Bigger
• Weight: Right- It got heavier
• Appearance: Wrong
