When animals hibernate, it means that they are going into a deep and prolonged sleep. Animals mostly do this in the winter times when the temperature outside is very cold and food is hard to find. Different animals follow different patterns of hibernation. Animals can put themselves into a deep sleep for as long as several months.

When animals hibernate it means that
they are going into a deep and prolonged
sleep. Animals mostly do this in the
winter times when the temperature
outside is very cold and food is hard to
find. Different animals follow different
patterns of hibernation.

3. Hibernation
Animals can put themselves into a deep
sleep for as long as several months. They
retreat underground or in caves where
they know they will be safe from
predators. During this time their
breathing and heart rate slows down.
Because of their decreased breathing
and heart rate, their body temperature is
able to drop close the to the temperature
outside. They use up reserves of fat
stored in their body to survive. Since they
are not doing much activity, this can last
them for the entire duration of their
hibernation.

4. Hibernation
Not all animals that hibernate sleep for
the entire time. For example, the
doormouse will horde large amounts of
food in its nest and wake up on the
warmer days to eat. Humans do not need
to hibernate because we have discovered
methods of producing food in the cold
and storing large amounts for when
there is none growing. You already sleep
during the night. Can you imagine going
to sleep for 6 months at a time?

5. Hibernation
PROJECT:
Try and research the different amounts
of time that hibernating animals sleep.
Also categorise your results as those that
go into complete hibernation and those
that sometimes wake up to eat.
