What
was
the
mother
upset
about?
2.
Why
was
the
writer
happy
to
help
her
mother?
The
mother
was
upset
because
a
family
of
snakes
had
made
their
home
near
the
house.
The
writer
was
happy
because
it
gave
her
an
opportunity
to
help
her
mother
and
invent
something
to
catch
the
snakes
without
hurting
them
at
the
same
time.
3.What
are
the
three
creative
steps
that
the
writer
takes
to
catch
the
snakes
without
hurting
them?
Step
1:
She
bought
a
stainless
steel
ice
cream
maker
and
froze
the
bowl.
She
added
ice
cubes
to
the
top
of
the
bowl
to
keep
it
cold.
She
placed
it
over
the
snakes’
habitat
during
the
day
so
that
the
snakes
would
become
sleepy
and
could
be
easily
caught.
Step
2:
As
above
she
did
the
same
but
placed
the
bowls
over
the
snakes’
habitat
in
the
evening.
Step
3:
As
above
but
added
a
net
to
catch
the
snakes.
4.
Why
did
cooling
make
the
snakes
less
active?
Snakes
do
not
have
a
way
of
keeping
warm
in
their
bodies.
They
get
warmth
from
the
sun
and
become
more
active
at
this
time.
When
the
sun
goes
down
at
night
they
cool
down
and
become
less
active.
So
extra
cooling
to
the
snake
would
make
them
even
less
active
and
easier
to
catch.

if
you

your
invention
to
others.
