Procedure:
- Divide the group of students into four groups, consisting
of wolves, rams, ewes, and lambs. For a group of 33 students
the ration is: (3) wolves, (6) rams, (12) ewes, and (12) lambs.
- Provide each lamb with a long flag. Affix the flag to lamb’s
body in a way that it can be removed by a wolf (i.e. in the
back-pocket).
- Provide each wolf with a long flag but of a different color
than the lambs. Affix the flag to the wolf’s body in a way that
it can be removed.
- Designate that one small corner of the gym or field is the
mountain “safety” zone for sheep. All other areas are open for
wolves and sheep.
The idea behind this
game is to simulate sheep and wolf behaviors. Sheep are herbivores
and often move to valleys or lower hillsides to forage or get
water. Ewes and lambs are always together in a group whereas rams
are often near or in their own groups. When sheep are attacked
by wolves, they almost always run for the highest point on a mountain
side to view predators chase. Wolves will go pretty high on a
ridge but can’t get to the steeper cliffs that sheep can. Wolves
often hunt in packs. Begin the activity with the rams, ewes, and
lambs grazing peacefully and the wolves out of sight of the herd.
Ewes: As soon
as grazing begins, the ewes should choose a lead ewe to watch
for predators. The ewes can pick a secret signal to communicate
to the rest of the herd that predators are approaching. When predators
are near, all the ewes gather their lambs and they sprint to the
mountain “safety” zone with the lambs. The main goal of the ewes
are to protect the lambs from the wolves. Ewes can also face off
a wolf by blocking the wolf from reaching the lamb but cannot
touch the wolf with their hands or feet. Ewes that have lost their
lambs can must run to the mountain for safety.
Lambs: Lambs
are totally dependent on the ewes. Each lamb is to hold onto a
ewe with both hands, around the ewes waist, and only follow the
ewe’s lead. Lambs cannot influence the ewe’s movement. Lambs have
fallen prey to wolves when their “flag” is removed from their
pocket. Once a lamb has “died”, they can move off to one side
but be able to watch the remainder of the activity. If the lamb
and ewe make it to the mountain, they stay there until the round
is completed.
Rams: Rams should
also pick their own signal for approaching predators. Since Rams
are often in separate groups they shouldn’t be with the ewes and
lambs during the beginning. Rams behave in several ways when predators
appear. They can group together, put their heads down and face
wolves or they group up with the ewes and lambs and head towards
higher ground. The main idea for the rams is to distract and/or
divert the wolves from the lambs and ewe groups. Rams have successfully
diverted a wolf when they get their “flag” from the back-pocket.
When a wolf gets diverted they are dropped from the pack and step
off to the side, but able to watch the remainder of the activity.
Once a ram has reached the mountain, they are also safe but can
not assist other ewes and lambs.
Wolves: Wolves
begin the activity out of sight of the herd. They try to get as
close to as possible without being detected. Wolves typically
work as a unit, so they can attempt surprising the herd in order
to kill a lamb or injured sheep. The wolves can move in any direction,
any time but can’t climb steep mountains. They can use any maneuver
(except pushing or shoving) to get to the lamb. A lamb is killed
when the wolf removes the “flag”. A wolf is out of the activity
if a ram removes its “flag”.
Playing a round:
Each round represents one year. A round is over when:
- All the wolves are
killed.
- All the lambs are killed.
- All the sheep are on the mountain.
- More realistic - one or two lambs have been killed and the
remaining sheep make it up to the safety zone because the wolves
stopped to eat the sheep they killed.
At the end of the round
(year), tally the number of surviving rams, ewes, and lambs. Sheep
that were killed will become wolves and wolves that were killed
become lambs in the next round. Continue the activity for five or
more years.
When the activity is
over, have the students discuss what happened in terms of animal
adaptations, predator/prey relationships, and the wolf and sheep
behaviors. Ask questions such as: What would happen if the rams
successfully diverted the wolves? What would happen if the wolves
were always successful in their hunt?
Have the students graph
the number of sheep that survived year to year.
Adaptation: This
game can be enhanced by adding tokens or small cubes as forage
for the sheep. The area can be divided into the four seasons:
spring, summer, fall, and winter. Spread the tokens or cubes around
the room in all the seasons. Start the activity in spring. When
you call out the name of the season, the sheep move to that range.
The sheep will be feeding on the cubes or tokens (picking up as
many as they can) while watching out for the wolves. For a sheep
to survive a year, they must have collected at least five tokens,
and in more than one season.
Suggested Assessment:
Have student’s find
pictures of other Alaska animals and discuss whether camouflage
is part of the animals adaptation or not. Give the student’s different
pictures of habitat from around the world. Have the student’s
draw or describe the type of animals that might live in that habitat
based on what they know about animal adaptations. How do the animals
adapt for different seasons?
