So Fragile, Yet So Strong.

TODAY'S ACTIVITY
Some of the favorite moments of "Project Pancake" was the cracking of eggs. We saved the shell-halves for a science experiment today.
First we held eggs in our hands and tried to crack them by squeezing them lengthwise. No one could do it. We then proceeded to the main event:
Our goal was to see how much weight these egg shells would hold before breaking. We placed the shells on a large block, shimmed to be level with the base. Then I asked for estimates of how many books they would support. Predictions ranged from "2 books" to "All the books!"
One by one the books were placed on top with great anticipation. The suspense built to a fever pitch as we placed ALL SEVENTEEN books from our story corner on top of the stack. We then began to add wooden blocks to the pile. We managed to stack TEN blocks on top of the stack before the shells below shattered.
We then took turns holding the same stacks with our hands. Most could do it for about ten to fifteen seconds before dropping all or part of it.
The total weight of the stack with books and blocks was 16 POUNDS!
The strength of these fragile egg shells was truly astounding!
TODAY'S STORY
Hedgie's Surprise, by Jan Brett. Poor Henny. This hen has her egg taken every morning by a naughty boy for his breakfast. All is O.K. until she sees a goose with her goslings. When she finds out the babies came from eggs, she feels sad. Hedgie (a hedgehog) decides to ease her pain with a trick. Each morning he hides her egg and replaces it with a substitute for the rotten kid to eat. Neither an acorn, strawberry, mushroom or potato full him up, and on the fifth day, he threatens to eat Henny if she doesn't provide him with an egg. At the crack of dawn the little imp bursts into the henhouse, pushes Henny aside, and seizes the surprise in her nest - a prickly Hedgie, curled up in a ball! He goes crying home, as Henny asks Hedgie what he has done with her eggs. He takes her to his nest, where they have hatched into a family of five little chicks all her own.
