I am really enjoying these egg experiments. Are you?
Let's go back to our egg in vinegar experiment. Today we will make our observations, check our hypotheses and test 2 new experiments with the egg!
Get out your notebooks! What did you observe today? How did the egg look and feel?
What do you hypothesize will happen to the egg after it sits in corn syrup?
Why did the egg shell go away and become bouncy?
Explanation: The vinegar reacts to something called calcium carbonate, which is inside the egg shell. The reaction creates a gas, creating the tiny bubbles on the outside of the egg. The shell dissolves, or goes away, and leaves a thin layer of the shell called a membrane. The vinegar can pass through the membrane. Since the vinegar can now get inside the egg, the egg gets bigger, or expands!
The vinegar has a large amount of water in it. The egg has a small amount of water inside. When water moves from something with a lot of water, through a membrane, to something with less water, this is called osmosis!
Let's end today with some alphabet exercise! Ready? Stand up and exercise with Jack Hartman!
