Mrs. Fernandez took several raw eggs with their shells (as seen in the picture below) and placed them in a container full of vinegar and let them soak over night.

null

The vinegar "decalcifies" (breaks down) the shell of the egg, leaving behind an egg with no shell...

null

The squishy, flexible membrane that is left behind after the shell is dissolved away is semi-permeable, like a cell membrane.

SCENARIO #1:

Read this!

Mrs. Fernandez placed a decalcified egg (an egg with no shell), which is 74% water and 26% other molecules, into a pure water solution.

Place the percentages (%) into the correct spot.
Then in the boxes outside label which is the HIGH concentration and which is the LOW concentration.
Then place the arrow to show which way the water molecules will move.

MAKE A PREDICTION: What will happen to the size of the decalcified egg and why?

A. The decalcified egg will get smaller, because it is losing water.

B. The decalcified egg will get smaller, because it is gaining water.

C. The decalcified egg will get larger, because it is gaining water.

D. The decalcified egg will get larger, because it is losing water.

SCENARIO #2:

Mrs. Fernandez placed a decalcified egg (an egg with no shell), which is 74% water and 26% other molecules, into corn syrup, which is only 24% water.
