Today we are doing an experiment that will take a couple of days to complete. We are making alien eggs for Halloween.
Egg shells are made out of calcium crystals. We are putting our eggs in vinegar, which is an acid. We think the acid will dissolve the shell, leaving the inside of the egg.
First thing we did was decorate our eggs.
After we decorated our eggs we put them in cups full of vinegar. We noticed that there was a lot of bubbles on the egg, and throughout the cup. We think that those bubbles are a reaction to the start of the calcium crystals being broken down. We also noticed that the colors that we put on our eggs were starting to disappear.
We are going to check on our eggs again tomorrow to see what changes happen.
Anna: I hope the eyeball I drew is still there!
Mina: When we were coloring, my hands got super colorful.
Jack: Wants to know how the vinegar gets in the egg. I think its like the vinegar is eating the egg. Om Nom Nom.
