Egg-cellent and Egg-citing Eggs

By Mary Van Dyke

Last week we studied and built nests. This week we're onto eggs. I check the list of preschool students’ allergies for eggs, and bring in a hardboiled hen’s egg per student - and a few 'egg-stra'. I bring celery for anyone with an egg-allergy. I bring in model alabaster and plastic eggs, and some real blown eggs from a selection of birds.

We look at the models, and students bring up the topic of "what's real?". The stone eggs are "real" stone and "models" of real eggs. The blown eggs are "real" shells with a hole-drilled, and have the yolks and whites blown out. The intro sparks student interest and conversation.
Students have fun cracking the hard-boiled eggshells, peeling the eggs, cutting and chopping and mashing the whites and yolks. We look for the air-pocket, the membrane, albumen (white) and yellow yolk and learn about egg anatomy.

Students enjoy the freedom to create their own egg dish  - and then eat it! Do you prefer to slice the egg white and yolk, or to make boats, mash the yolk separately, or decorate your egg with capers? Do you like the entire egg, or just the yolk, or just the white? The egg is a nutritious snack with protein, vitamins and other nutrients.

The Quail's egg is speckled

At the end of the class, we gently make nests with hands and pass around the big Ostrich egg. It’s quite heavy, and has got a shiny dimpled texture. Then we circulate the tiny speckled Quail’s egg, the blue Araucana hen egg, and the very long white Embden Goose egg. I show pictures of the birds that lay these eggs.

IKEA layer puzzle showing egg to chick process

The preschool students ask lots of questions about eggs and chicks. I answer at age-appropriate level. We tell the story of a hen laying an egg and a chick hatching out with an old IKEA wooden layer puzzle.

Here are some newly-laid eggs from a friend's farm.

Fresh warm eggs

Check out the Five Reasons To Keep Chickens with drawings of a Rooster and Hens from A First Book of Nature by Nicola Davies and Mark Hearld:... "5. Collecting eggs when they are still warm from under the hen is wonderful."

If you are working with older children, maybe one spring, you can incubate fertilized eggs and hatch chicks to give back to a local farmer? A 4-H Cooperative Extension office in your area might be hosting the Embryology Project? Or arrange to go visit a flock of laying hens, and maybe even gather a warm egg or two, at an educational farm near you?

• Check various sources: the American Egg Board, nutritionfacts.org, nutritiondata.self.com and others. Protein, nutrient content is more clear,  than some of the health benefits that are still being debated.
