Marlo's Egg osmosis experiment

Egg Osmosis ExperimentMarlo Medina 8-73

Purpose.To observe osmosis in

a cell.Place eggs in vinegar

to remove shell.Measure weight of

egg.Measure size of egg.Place one egg in water

and the other one in corn syrup.

Measure again

Hypothesis (Egg in Water)Egg will be heavier.The size would be

the same.The egg will look the

same.

Hypothesis (Corn Syrup Egg)The egg might

change its colour.Size would be the

same.The egg might get

heavier cause of the corn syrup.

Before

• W 71.5g• S 16cm

• 71.4g• 16cm

Observations After VinegarBouncySquishyBubbles in the

beaker

Observation After SyrupDentedInflatedBrown colour

Observation After WaterThe egg got fatter.Same colour.Higher

concentration to lower concentration.

Conclusion (Water Egg)Water moved into

the water egg.The egg had a lower

concentration.Water moved from

higher concentration to lower concentration.

Conclusion (Corn Syrup Egg)The egg got smaller.Water moved out of

the egg.The water moved

from higher concentration to lower concentration.

This is osmosis.

Conclusion HypothesisThe corn syrup egg

will get heavier. (Wrong)

The corn syrup egg would be the same size.

(Wrong)

The water egg will be heavier.(Right)

The water egg would be the same size. (Wrong)

ResultThe corn syrup egg

got lighter.The corn syrup egg

got smaller.

The water egg got heavier.

The water egg got larger.
