Tough as an Eggshell

Math is not the only thing we do in our household!  This is a guest post by my husband about a fun science experiment he did with the kids:

Recently I stumbled onto The Everything Kids’ Science Experiments Book  on one of our bookshelves. It was a present from someone on Katie’s birthday a few years ago, and at that time I thought her too little for it. And, to be honest, I didn’t consider myself sufficiently ‘handy’ for this.

After flipping through the pages, I decided some of the experiments even I should be able to do. And that is how, one spring evening, our whole family found itself contemplating the hardness of eggshells and the significance of domes!

This simple experiment starts with taking 4 egg half-shells, trimming them down to about the same size and arranging them in a rectangle.
Then we … pile books on them! The kids were very excited and started making predictions about how many books it’d take to crush the shells.
To their, and our, surprise these predictions fell short. The books kept piling.
Then, with a slow crunching sound, one shell  gave way.
The rest held longer, but one-by-one they too succumbed. And this was all that was left of the eggshells, aside from pictures, fun memories and some vague plans to do more hand-on experiments with the kids on our part.

    Hmm, ‘Guest Husband’, it looks like you attracted the blog’s first spam comment! :/

    Egg shells have to be strong to protect the little chicks in them! But it’s true that
    they’re much stronger end-on than you think.
