1. EGG OSMOSIS Hannah
Magnaye
EXPERIMENT 8-16

2. PURPOSE
observe osmosis in
cell
1) eggs in vinegar
remove shell
2) measure weight
of eggs using
balance

3. PURPOSE
3) measure size of
egg string and
measuring tape
4) one egg corn
syrup, other egg
water
5) weigh and
measure eggs again

4. HYPOTHESIS (CORN SYRUP EGG)
Weight: lighter
Size: it will shrink
Looks: small and
mushy

5. HYPOTHESIS (WATER EGG)
weight: heavier
size: will get larger
looks: blown up and
enlarged

6. MATERIALS
Eggs
Balance
Measuring tape and
string
Corn Syrup
Water
2 Beakers
Vinegar

7. OBSERVATIONS
Before After
Corn Weight: 67 grams Weight: 44 grams
Syrup Size: 16.1 cm Size: 13.2 cm
Before After
Water Weight: 77 grams Weight: 91.9 grams
Egg Size: 16 cm Size: 17.5 cm

8. OBSERVATIONS
bubbles rising from
egg
more bubbles and
egg floats to top
egg still floating and
foam form at the top

9. OBSERVATION
24 hours in vinegar
 foamy, large
 no longer has shell
 squishy

10. OBSERVATION
24 hours in water
 egg has sunk and
looks larger
 24 hours in corn
syrup
 egg looks shriveled

11. CONCLUSION
Water Egg:
 got larger,
 water moved into egg
 water had higher
concentration
 egg had lower
concentration

12. CONCLUSION
Corn Syrup Egg
 got smaller,
 water moved out of
egg
 egg had higher
concentration
 water had lower
concentration

13. HYPOTHESIS
Hypothesis for water Hypothesis for corn
egg was correct. syrup egg was
o Weight: it got heavier correct.
(correct) o Weight: it got lighter
o Size: it got larger (correct)
(correct) o Size: it shrunk and
o Appearance: looks looks shriveled
blown up and enlarged (correct)
(correct) oAppearance: smaller
and mushy (correct)
