Winter is the perfect time to teach hibernation to preschoolers. After all, hibernation is all about what (some) animals do in the winter. The very best time to do hibernation activities with preschoolers is during your winter theme in preschool. I like to snuggle them in between classic preschool winter activities about ice and snow and an arctic animals theme. We spend a few weeks learning about all the characteristics of winter, and then we spend a week or so learning about hibernating animals. That week of doing hibernation activities is the perfect segue into introducing an arctic animals theme.
