March 12, 2013

Another round of science experiments involving eggs....this time started out with Jed trying to break an egg with brute strength.  Although he's been working out, he's no match for the shape of an egg, cleverly designed to distribute weight evenly to avoid breakage, most notably by mama bird as she settles onto her clutch.  Next we broke the egg at the pointy end to see if we could find the air sac at the round end.  It was easily visible, created by the membrane not quite reaching the end of the egg and stretching across the gap.  Pretty cool.
