Review what we found when we cracked open eggs and examined what was inside of them. Evaluation Listen carefully to how children answer the questions at the end of the lesson. If they are confused, be sure to re-do experiments or at least talk over what we asked and learned. Eggshells are porous or have little holes in them so air can get in and out of the egg. If we had fertilized eggs, the baby chicks would need air to live and grow.
Air is found inside the egg in an air sac.
Eggs wobble when they roll so they won't go far from a mother hen and they will stay inside of a nest. Probably the very best way to see if children understood this lesson is to let them teach it to someone else. Encourage children to take these experiments to other classes, their girl or boy scout groups or home. Write recipes and experiment with frying, poaching, steaming, and baking eggs. Pick out different recipes which include eggs as an ingredient, from quiche, to cupcakes, to cookies,to casseroles, to meringue on a pie.
