Egg Osmosis Experiment

Purpose

To observe osmosis in a cell.1. Place egg in vinegar

to remove shell.2. Measure weight of

egg using a balance .

3. Measure size egg using measuring tape.

Purpose

To observe osmosis in a cell.

To place one egg in water

To place one egg in corn syrup

Hypothesis

Corn Syrup

Size: bigger

Weight: heavier

Looks like: bigger than the usual and slimy

Hypothesis

• Water

Size: the same

Weight: the same

Looks like: no difference

Materials• Eggs

• Beaker

• Balance

• Measuring Tape

• String

• Vinegar

• Corn syrup

• water

Observations

Before After

Corn Syrup Weight : 71.5 g Weight: 50.6 g

Size: 16 cm Size: 14.5 cm

Water Weight: 71.4 g Size: 87.5 g

Size: 16 cm Size: 18.5 cm

Observations

After 24 hrs. in vinegar: egg shell disappeared, squishy and bouncy

After 24 hrs. in corn syrup: egg is dented and deflated

After 24 hrs. in water: egg got fatter

Observations

Corn Syrup Egg(after)

Water Egg(after)

Conclusion

Conclusion

The corn syrup egg got smaller because water moved out of the egg. This was due to the fact that the egg has a higher water concentration than the corn syrup. The water moved from higher concentration (egg) to lower concentration (corn syrup).

The water egg got bigger because water moved into the egg. This was due to the fact that the egg had a lower concentration of water. The water moved from higher concentration (water) to lower concentration (egg).

Hypothesis Conclusion

Water Egg Size - wrong Egg got bigger did not remain the same

Weight - wrong Egg got heavier not the same

Corn syrup Egg Size - wrongEgg did not bloat up instead inflated

Weight - wrongEgg did not get heavier but lighter
