Inside An Egg

Break an egg into a dish. Yes, all of us have seen the inside of an egg before. But this time try looking at it in a different way, examine it closely and question what each part is for.

See the yellow part in the center? That’s called the yolk. The clear gooey part ( sometimes called the white) is called the albumen. The yolk and albumen are food for the baby bird growing inside a fertilized egg. The albumen also provides a “cushion” to keep the baby from being hurt if the egg is bumped or moved. Now, look for the two white, twisted “strings” at opposite sides of the yolk. These have a funny name. They’re called chalazas (kuh-lay-zuhs). They keep the yolk anchored in place so it won’t be damaged.

Now help make your child make a diagram of an egg using construction paper. On white paper draw the albumen; when finished, cut it out. Glue albumen on a clean sheet of construction paper. On yellow paper draw the yolk; when finished, cut it out. Glue yolk on top of albumen. Using cotton balls; form the chalazas. Glue chalazas on the sides of the yolk. Lastly, have child label diagram.
