I
joined
the
captain
in
the
small
boat
because
I
think
the
journey
to
be
challengeable.
The
only
instruments
the
captain
was
allowed
to
take
were
a
compass
and
a
quadrant.

We
couldn't
get
a
correct
reading
from
the
quadrant
as
the
weather
was
bad.

Working
out
our
position
took
us
a
great
deal
of
time
which
made
us
worried.

The
extreme
lack
of
water
was
the
hardest
to
cope
with.

Get
into

these
questions.

history?
Do
you
agree?
Give
your
reasons.
2.
What
kind

the
only
qualities
needed
for
a
good
captain?
Get

These
are
some
Viking
sailing
directions
from
Norway
to
Greenland.
Sail
west
but
keep
to
the
north
of
the
Shetland
Islands
so
you
can
hardly
see
them
in
good
weather.
Stay
far
enough
south
of
the
Faroes
so
that
their
steep
mountains
are
just
halfway
up
the
horizon.
Keep
south
of
Iceland
so
that
you
cannot
see
land
but
just
coastal
birds.
Follow
this
route
and
you
should
reach
Greenland.
Use
the
information
from
the
listening
to
explain
these
sailing
strategies.
Vikings
used
to
prefer
to
sail
following
the
coastline
so
they
could
check
that
they
were
on
the
correct
route.
Vikings
used
birds,
and
natural
features
like
mountains,
to
direct
their
ships.
Sayings
What
do
they
mean?
1.“If
you
can
read
the
ocean,
you
will
never
be
lost.”
Study
the
waves
so
that
you
can
read
what
will
happen
in
the
weather
or
when
land
is
close.
What
do
they
mean?
2.
“Watch
for
when
the
sun
grows.”
The
position
of
the
morning
sun
on
the
horizon
can
help
you
check
your
course.
What
do
they
mean?
3.
“the
stars
are
the
yes
of
Heaven”
“the
stars
can
give
you
information
about
your
position
and
can
help
you
“see”
where
you
are.”
What
do
they
mean?
4.
“When
the
bird
flies
out
to
sea,
the
sea
will
grow
calm.”
Birds
do
not
fly
out
to
sea
if
a
storm
is
coming
so
a
bird
flying
away
from
the
shore
means
good
weather.
