Students
will
learn
about
magnification
and
how
a
magnifying
lens
works.
They
will
examine
a
variety
of
different
objects,
first
without
a
magnifier
and
then
with
a
magnifier,
and
compare
what
they
observe.
They
will
practice
observing
details
of
these
objects
with
magnifying
lens.
The
purpose
of
this
activity
is
for
students
to
learn
about
observation
skills
and
how
tools
can
help
people
make
observations,

Students
will
be
introduced
to
different
species
of
macroinvertebrates.
They
will
hypothesize
why
each
insect
looks
the
way
it
does.
Then
students
will
make
observations
of
macroinvertebrates
in
an
aquarium
in
their
classroom.
For
an
optional
extension,
teachers
can
take
students
to
a
local
stream
or
pond
to
conduct
field
observations.
The
purpose
of
this
activity
is
to
introduce
students

Each
student
will
keep
a
science
journal
during
each
of
the
four
seasons.
Students
will
record
observations
of
the
general
outdoor
environment
they
visit
and
then
will
make
observations
of
one
specific
item
from
the
habitat
in
each
season.
At
the
end
of
the
school
year,
students
will
make
comparisons
of
their
seasonal
drawings
and
share
the
results
with
the
class.

Using
a
color
chart,
students
will
make
observations
outside
during
each
of
the
four
seasons.
During
each
session,
they
will
try
to
find
as
many
colors
as
possible
and
record
what
they
see.
As
a
class,
they
will
make
charts
describing
the
colors
they
find
in
each
season.
At
the
end
of
the
school

In
this
activity,
students
will
record
a
list
of
things
they
already
know
about
hummingbirds
and
a
list
of
things
they
would
like
to
learn
about
hummingbirds.
Then
they
will
conduct
research
to
find
answers
to
their
questions.
Using
their
new
knowledge,
each
student
will
make
a
hummingbird
out
of
art
supplies.
Finally,
using
their

The
purpose
of
this
resource
is
to
develop
an
understanding
of
how
water
flows
through
different
soils
and
how
it
is
transformed
when
it
flows
through
these
soils.
Students
time
the
flow
of
water
through
different
soils
and
observe
the
amount
of
water
held
and
also
the
filtering
ability
of
the
soils.
They
will
also
observe
the
filtering
ability
of

In
this
activity
students
construct
a
sundial
and
use
it
to
observe
the
movement
of
the
sun
through
the
sky
over
the
course
of
a
day
by
marking
changes
in
the
position
of
a
shadow
once
each
hour.
Students
determine
the
approximate
time
of
solar
noon
at
their
school
as
indicated
by
the
time
of
the
shortest
shadow.
They
revisit
the
site
on
a
subsequent
day
to
estimate
the
time
of
day
using
their
sundial.

The purpose of this resource is to familiarize students with the importance of perspective and various scales of remotely sensed data. Students create a 3-D model of an area and develop a classification system for the landforms in their model. The maps can then be used to answer certain questions about the environment.
