When winter comes to cold countries, some animals do something amazing — they fall into a deep, special sleep called hibernation.
Tap Next to find out why they do it — and try some fun activities along the way!
Animals hibernate to survive one tricky season. Tap the season you think is hardest for them to find food.
Hibernation is not the same as a night's sleep. The animal's body almost switches to "low power mode" to save energy.
| Normal sleep 🛏️ | Hibernation 🐻 |
| Wakes up easily | Very hard to wake |
| Lasts one night | Can last weeks or months |
| Heartbeat normal | Heartbeat very slow |
Let's see that slow heartbeat for ourselves on the next slide… 💓
To use less energy, a hibernating animal slows its heartbeat right down. Tap the button to help the bear go into hibernation.
See how the heart barely moves when it is very slow? That saves lots of energy!
Before hibernating, animals eat lots of food in autumn to build up fat. That stored fat is the fuel their body slowly burns all winter.
Drag the berries onto the bear to fill its fat store. Fill it up to get ready!
Not every animal hibernates. Tap the animals that really do hibernate. Find all 0 of them!
When spring returns, the air warms up and food appears again. The animal's heartbeat speeds up, its body warms, and it slowly wakes up — hungry and ready to explore!
Hibernation isn't lazy — it's a clever survival trick! 🧠
