EGGS!

Our chicken eggs should hatch March 11.
Second graders discover that hard-boiled eggs spin quite nicely.

EGGS EGGS EGGS!    
This week, most classes investigated the structure of the chicken egg.  Yolk, egg spot, membranes.  Albumen (did you know there was a thick and thin egg white?)

Holes in the eggshell for the developing embryo to breath.  Egg shapes differ depending on the environment of the nest; seabird eggs are pointy so they will roll in a circle and not roll off a cliff.
 
 
Not all were thrilled with the textures.
And some first-graders definately were.
We're coloring the shells for Easter projects.
