Hibernation Unit

Posted on

Our preschool science curriculum features both season and animal units, so with winter here it’s the perfect time to study the change in the season and animals who are either greatly effected by the winter weather or are cold climate animals. We started out this winter season with a hibernation unit.

Hibernation Unit

It’s amazing the things that I have learned while homeschooling my son. I was doing research and learned that bears don’t “technically” hibernate under the original definition of hibernation. Animals who truly hibernate go into a very deep sleep and cannot be disturbed. They can be moved without even being aware of it. Bears however sleep for weeks at a time and can be disturbed. Animals who hibernate include; badgers, bats, chipmunks, dormouse, ground squirrels, hamsters, groundhogs, hedgehogs, nighthawks, prairie dogs, raccoons, and skunks.

Books

I started by reading Big B lots of books about bears and hibernation. Our library has an entire section of science children books on animals. I got a few books that teach about bears and other animals who generally hibernate. I also got a few story books where the animals (mostly bears) are preparing to hibernate.

Snacks

Hibernating animals build up fat reserves (and in some cases store foods) to sustain themselves through the winter. They will eat things like berries, nuts and other vegetation. Offer some of these foods to your child as snack (considering allergies) and talk to them about how these foods help the hibernating animals make it through the winter.

Cave Building

We talked about how animals build or seek out shelter to protect themselves while they are hibernating. Big B and his dad built a cave for him play bear and act like he was hibernating.

Fat Storing Experiment

I ran across this Animals in Winter science experiment from Preschool – What Fun We Have. I felt like it was the perfect way to show Big B how animals store fat to help them stay warm during the winter.

I started out with two bags, shortening, and ice.

I covered Big B’s hand with one of the bags and then handed him a few pieces of ice

I then liberally covered his hand with the shortening and covered it with the second bag. I handed him the ice again.

The shortening represents the additional fat that helps protects the animal from the cold weather.

Big B now has a better idea of how and why animals hibernate.

    Thank you for posting this. Sounds like fun.
    With this experiment. Did you put the Crisco directly on his hand or on top of the bag that was on his hand?

      No. I did not put the crisco on his hand. I had a sandwich bag on his hand, put the crisco on top, then covered everything with another bag so the crisco did not get everywhere.
