When the students heard that they were about to save the hamsters, their eyes widened and their hearts raced. They listened carefully.
Zhang Zian took the opportunity to explain the science behind it first.
Hibernation was a basic instinct to many animals. From small rodents, to reptiles, to bears, they all chose to hibernate to withstand the harsh weather when food became scarce. During hibernation, the animals had lower body temperature and slower metabolisms. They could spend the entire winter without eating, drinking or moving.
Before entering hibernation, animals made preparations to fatten themselves up, so that they had enough fat to consume and to keep them warm. They chose a safe, quiet, and warm nest to hide out. By the time they came out, spring already arrived.
