This week, we did a really easy & fun science experiment. All you need is an egg (or two, in case one breaks), some white vinegar, and a jar. You put the egg in the jar, cover it with the vinegar, and then let it sit for 3-4 days (changing the vinegar once, after the first 24 hours). The acid in the vinegar breaks down the eggshell (base), so that you're left with just the translucent membrane.
To supplement our experiment, we read "The Egg," which is a Scholastic "First Discovery book." I love these books as they let you "look inside" things. After 4 days, we found that the egg was soft and bouncy (we bounced it -carefully- on the kitchen table). We also held it up to the window so we could see the "nucleus" (yolk) and the "cytoplasm" (the whites) inside. Ocean also enjoyed looking at it with a flashlight.
This is what it looked like right away, you can already see the shell breaking down.
Ocean's drawing of the experiment (although, of course, our egg did not produce a chick...I think that was wishful thinking on her part). She also practiced writing the word, "egg."
So cool how it glowed in the sunlight.
