Egg Osmosis Experiment

Purpose

To observe Osmosis in a cell.

Place egg in vinegar Measure weight of egg Measure size of egg

Purpose (continued)

Place one egg in water and other egg in corn syrup.

After 24 hours. Weigh, measure eggs again.

Hypothesis

Egg in corn syrup: Weight, lighter Size, the same Egg, look the same

Hypothesis (continued)

Egg in water: Weight, heavier Size, bigger Egg looks, a little

bigger

Materials

Eggs Beaker Balance String Measuring tape Vinegar Corn Syrup Water

Observations

Bubbles out of egg, in vinegar

After egg out of vinegar, squishy and bouncy

Shells were gone

Observations (continued)

Egg floats, corn syrup egg soaked in water,

bigger/fatter egg soaked in corn syrup,

deflated

Before after

Corn Syrup:

W-71.5S-16cm

W-50.6S-14.5

Water: W-71.4S-16cm

W-87.5S-18.5cm

Conclusion

Egg in water: -got larger water from beaker moved

to egg high concentration (water

in beaker) to lower concentration (egg)

Conclusion (continued)

Egg in corn syrup egg is deflated water from egg moved to

beaker high concentration (egg)

to lower concentration (corn syrup)

Conclusion (continued)

Hypothesis for water egg: Egg would look bigger,

correct. Egg is heavier, correct Egg has a bigger size,

correct

Conclusion (continued)

Hypothesis for corn syrup egg: Weight of egg, lighter.

correct Thought that size, same.

But, deflated. Wrong Thought that egg looks,

same. But, smaller. Wrong.
