2. Purpose
 Observe osmosis in a cell
 Place eggs in vinegar to
remove the shell
 Measure weight of the egg
using a balance
 Measure size of the egg
using string and measuring
tape

3. Purpose
 Place one egg in corn syrup,
and one in water
 Weigh and measure the eggs
again

4. Hypothesis
Corn Syrup
 I think the egg will weigh more
 The size will stay the same
 It will look dark and sticky

5. Hypothesis
Water
 I think the water egg will weigh
the same
 The size will get smaller
 It will look clear

6. Materials
 Eggs
 Balance
 Measuring Tape
 String
 Corn Syrup
 Water
 2 Beakers
 Vinegar

7. Observations
Vinegar
 There is bubbles after a few
minutes
 More bubbles at top, and eggs
are floating
 Eggs are still floating, and foam
is forming at the top

8. Observations
Corn Syrup
 It no longer has a shell, and it
feels squishy
 After sitting in corn syrup for 24
hours, the egg looks shrivelled
 After sitting in water for 24
hour, the egg is not floating,
and it looks like it got larger

9. Observations
Water
 After sitting in water for 24
hours, the egg is not floating
 It looks like it got larger

10. Before After
CS W 67 g W 44 g
S 16.1 cm S 13.2 cm
H2o W 77.4 g W 91.9 g
S 16 cm S 17.5 cm

11. Conclusion
Water egg
 Got larger because water
moved into the egg
 Egg had a lower concentration
of water than water
 Water moved from high
concentration(water) to lower
concentration(egg)

12. Conclusion
Corn Syrup
 Got smaller because water
moved out of the egg
 Egg had a higher concentration
of water
 Water moved from higher
concentration to (egg) to lower
concentration(corn syrup)

13. Hypothesis
Water Egg
 Size: wrong
 Weight: wrong
 Appearance: wrong
Corn Syrup Egg
 Size: wrong
 Weight: wrong
 Appearance: wrong
