EGG OSMOSIS EXPERIMENT Tinille Medina 8-73
PURPOSE - To observe osmosis in a
cell.
STEPS: 1. Place egg in vinegar
2. Measure weight of egg
3. Measure size of egg
PURPOSE (CONT.)
4. Place one egg in water, other in corn syrup
5. Weight and measure eggs
HYPOTHESIS Water egg:
Weight the same
Size smaller/tinier
Looks fatter
HYPOTHESIS (CONT.) Corn Syrup egg:
Weight heavier
Size wide/large
Looks different
MATERIALS Eggs Beakers Balance String Measuring tape Vinegar Corn Syrup Water
OBSERVATIONBEFORE AFTER
Corn Syrup
Weight: 71.5Size : 16 cm
Weight: 50.6Size: 14.5
Water Weight: 71.4Size: 16 cm
Weight: 87.5 gSize: 18.5 cm
• Vinegar: bouncy squishy a large amount of foam at top.
OBSERVATION Egg in Corn Syrup:
dented deflated
Egg in Water(24 hrs.): fatter larger
CONCLUSION Egg in Water:
got fatter, larger water, in egg H.C (water) to L.C (egg)
CONCLUSION Corn Syrup Egg:
got smaller water, out the egg H.C (egg) to L.C (corn
syrup)
CONCLUSION My hypothesis is incorrect because;
Water Egg: Weighed more (wrong) Size, got bigger (wrong) Look, fatter (right)
Corn Syrup Egg: Weighed, less (wrong) Look, became soggy (wrong) Size, smaller (wrong)
