Frogs In Winter
Have you ever wondered what happens to frogs in winter? Where do they go when the temperatures drop and the snow flies? In late autumn, frogs will settle into the mud at the bottom of a pond. They don't freeze solid because frogs have a way to increase the amount of glucose in their bodies. Glucose is a form of sugar, and it creates a sort of antifreeze that keeps the frogs cells from freezing while they hibernate. Frogs also change the way they breathe! They take in oxygen from the pond water right through their skin, so they never need to come to the surface until spring. In this activity, you and your child will create a tasty treat that will teach your child exactly how frogs survive a freezing season.
