MeandBear
Hunters who have skinned a bear for the first
time are often starded to recognize how
similar a bear's anatomy is to a human's. We
share severalphysical characteristicswith
bears. But Smokey Bear, Paddington@Bear,
the Care Bears@,
and our own teddy bears
show us that we have very special feetings
for bears. Do we see something of ourselves
in bearsf
Play "Me and Bear'?in order to learn more
about bears...and yourself.
Ihe game ineludes:
. The "Bear Grid" on page 45
. 12 "Me and Bear" people cards on
page 43
. Answer key on page 64
You need:
o Scissors
' A pencil
Obfeetlve:
l. To discover the similarities berween
bears and people by matching people
cards to the bear grid, and
2. To make three matches in a row.
Belone playlng:
.
Cut out the people cards on the next
page.
lb play:
I. Shuffie the cards and deal six cards to
each player. Decide who goes first.
2. When it is your turn,look at the playtng
grid, and match one of the six people
cards in your hand with the bear picnre
on the board. Be sure to read the
information on the card out loud before
you place it on the board. Some of the
people cards have false statemens. If the
card is false, you may eirher discard it, or
play it to block your opponenr.
3. Only one people card can be placed on
any bear space.
4. If you are the last player to put down
the card that makes three in a roq you
win that round, as long as all three
cards are tme statements. In order to
win, there must be three correct
matches. If you put down the last card
in a row, and one was incorrect, you
los€! Whoever wins rwo out of three
games is the champ!

Bearsand peopleeat
plants, so they have similar
kinds of teeth-flat molars
for grinding. The polar
bear has shalp molars
becauseit mainly eats
meat.
2.
Bearsoften stand on their
hind legs to see things at a
distance, to sniff, or to
hear better.
A bear track is deeperthan
a human track because
bearsare heavier than
people. Humans and bears
both walk on their toes.
D.
Becausethey are mammals,
bearsand people share
severalcharacteristics.
Their young feed on the
mother's milk. They have
hair. Bears and people are
warmblooded.
^)
.).
The prints of an adult
person and a bear show
five toes, and are about the
sarnesize. Bearsand
people are plantigrade;
they walk with the foot flat
on the ground.
l

7. Bearsand humans have
o
O.
similar needs: clean water.
shelter, food, and "space."
Becausehumans share
these things with bears,
no bear population is in
trouble today.
10.
Like humans, bearshave
binocular vision. Because
the eyesare arranged close
together in the front of
the face, bearsand
humans can judge depth
and distance. The ability
to judge depth is
important to a predator.
t-t
ll.
Mother bears,particularly
gizzltes, are very
protective of thet young.
Fluman mothers share this
maternal instinct.
Humans and bears
demonstrate great
curiosity. In their search
for something to eat,
bears examine everything
in their path.
O.
The bear shows amazing
skill in the use of its front
paws. The bear usesits
non-retractable claws as
tools when diggrg roots,
or as weapons for grppi"g
prey. Young bearsuse their
claws for scaling trees.
9. Eating meat) fruits, and
vegetablematter) bearsand
people are omnivores. In
addition, bears also share
people's love of '"sweets."

LZr.
Human mothers and
bear mothers are very
protective of their young.
Like human children,
bear cubs will stay with
their mothers until they
are ready to have their
own families.

Check below to make sure your three in a
row are all true statements. When laid on
the Bear grid, the correct placement of
people cards looks Iike this:
l. True; 2.True; 3. True; 4. False;
5. True; 6. True; 7. False; 8. True;
9. True; 10. True; II. True; 12. False.
Hibernation Heartbeat
Although bears are not true hibernators,
they still go into a light sleep, waking up
occasionally throughout the winter, even
leaving the den for short intervals.
When a bear sleeps in the wintern its pulse or
heartbeat slows down to help the bear save
energy. Your pulse doesntt slow
down this much when you sleep, but
it is slower than when you are active.
Procedure:
Find out how low your pulse is when
you wake up in the morning by gently
pressing your thumb to the side of your neck in
the groove beneath your jawbone. Youtll feel your
heart beating a pulse, or surge of blood through
your artery. For 6O seconds, count how many
times your heart beats.
Then at another time during the day, when youtre
more active, stop to take your pulse again, ls it

How Mony Bears Wiil Get Fot for the Winter?
Spread squares of paper ('berries') over a large defined area. Use at
least 10 squares for every player. The players pretend to be bears, and
each one finds a'den'(a tree, bush or chair).
One 'bear'has two cubs, which he or she holds by their hands. T\uo
other bears have problems gathering food: perhaps one has a
porcupine quill in his or her paw and can only hop, and the other bear
has a sore nose and must protect it with one hand at all times.
The leader signals when it is time to start to find berries. Each bear
picks up one square ofpaper and takes it back to his den and then
goesback for more, one at a time.
ri:,
"..:f
when the leader decidesthe players have had enough time, or when
the berries are nearly gone, he or she calls, vinter is here,'and all
the bears must go back to their dens.
Discuss whether the bears with problems and the mother bear, who
had to hrng onto her babies, managed to find as many berries as the
other bears. Will all bears be able to get enough food?
