Demonstration R.A.F.T.S. Assignment
Role: Scientific
Explorer
Audience: Other
scientists
Format: Journal
Entry
Topic: Tundra
Biome
Strong
Verb: Describe
Assignment:
For this assignment you are an explorer in a tundra biome, which you have never
encountered before. You are
keeping a journal of your journey with each biome you encounter to describe the
plant and animal life found there are well as the weather and anything you find
interesting and different than your native habitat. This will be used to inform other scientists about the
Tundra biome you have encountered.
Journal Entry Dated March
30, 2015
Today we have entered an area in Northern Canada that the natives call Tundra. This area is barren with not much plant
or animal life. In March the
ground is still covered in snow and it is very cold. We have seen a few small animals such as: rabbits, foxes and
an owl or two. Yesterday we came
across a large herd of caribou about 100 miles south grazing on small patches
of grass making their way through the snow. This ecosystem has some very limiting factors that effect
number and types of plants and animals that can survive here. Those factors include the amount of
food, water, space, and shelter available. Earlier this morning I spoke with a local who described to
me that they have a short period of warmth in the summer months for plant life
to grow and that trees are unable to take root because the soil remains frozen
for all but a few weeks out of the year.
They also have a small amount of rain, which inhibits plant life from
taking off. I am told that besides
the rabbits, foxes and owls I have seen other small rodents can survive here as
well as weasels. This biome has a
carrying capacity much like that of a Desert very few plant and animals can
survive because of the inhospitable climate.
