Thursday morning
I have caterpillars! They will turn into butterflies.
There are six. At least three will stay alive. And three might die.
They are really really tiny black caterpillars.
Friday morning
They have shedded some skin now and there's a lot more balls of food so they've been eating really good.
The webbing has gotten shorter and there's a little bit of shedded skin in the webbing. There's a little bit of webbing on the other side, too.
They're all a little big longer or a little bit shorter than a half of an inch.
Friday night
The big ones are between 5/8 and 3/4 of an inch, but the little one is only exactly a half of an inch.
They have grown a lot in 12 hours!
We completed a unit about butterflies and moths and now we're raising a batch of six Painted Lady caterpillars. We ordered this kit and they were shipped to us from Carolina Biological Supply Company. Addy had fun tracking their FedEx delivery route on Google Earth from North Carolina to Ohio to our house with stops in between. Unfortunately our camera is broken so we can't track their growth with photos yet.

Spinning eggs
This is me spinning eggs for an experiment. The experiment is that I have to spin the eggs and figure out which two eggs have been cooked and which one didn't get cooked — which two are the hard-boiled eggs.
I figured it out by spinning the eggs and I had to put my hand on it and take it off right away. And if it kept spinning, it wasn't hard-boiled. If it stopped spinning, then it was hard-boiled.
Because the hard-boiled eggs were cooked, so the shell inside wouldn't spin around.
Mom's note: The white and yolk wouldn't continue to spin in the cooked egg.
