The purpose of this resource is to measure the salinity of the water at your hydrology site. Students use a hydrometer to measure the specific gravity of the water sample, and use a thermometer to measure the temperature. With these two values, students will use tables to determine the salinity.

The
purpose
of
this
resource
is
to
log
soil
data
using
a
Davis
soil
moisture
and
temperature
station.
Soil
moisture
and
temperature
sensors
are
installed
at
multiple
depths
and
a
station
is
set
up
to
measure
and
record
measurements
at
15
minute
intervals.
These
measurements
are
transferred
to
your

Students
participate
in
a

in
which
they
collect

calculations
and
then
try
to
fool
other

of
this
resource
is
to
sure
the
distribution
of
different
sizes
of
soil
particles
in
each
horizon
of
a
soil
profile.
Using
dry,
sieved
soil
from
a
horizon,
students
mix
the
soil
with
water
and
a
dispersing
solution
to
completely
separate
the
particles
from
each
other.
Students
shake

to
fully

The purpose of this activity is to measure surface temperature with a handheld Infrared Thermometer (IRT). The instrument is pointed at the ground to take surface temperature readings. Intended outcomes are that students will learn to use an infrared thermometer, and understand how different surfaces radiate energy. Supporting background materials for both student and teacher are included.

this
activity,
students
download
NASA
Hubble
Space
Telescope
(HST)
images
of
the
Martian
polar
ice
caps
in
summer
and
winter.
Using
image
processing
techniques,
students
measure
and
compare
various
images
of
the
changing
Martian
and
Earth
polar
ice
caps.
By
completing
this
activity,
they
will
understand
that
the
sizes
of
the
polar
ice
caps
on
Earth
and
Mars
depend
on
the

This
NASA
Module
investigation
compares
and
contrasts
physical
processes
that
occur
on
Both
Earth
and
Mars.
Students
are
given
unidentified
images
of
Earth
and
Mars.
Their
task
is
to
arrange
the
images
into
pairs
that
show
evidence
of
similar
physical
processes.
Then
they
identify
each
image
as
one
of
Earth
or
of
Mars
by
comparing
and
contrasting
physical
features
that
they
observe
in
the
image
pairs.

types
of
clouds
and
how
many
of
three
types
of
contrails
are
visible
and
how
much
of
the
sky
is
covered
by
clouds
(other
than
contrails)
and
how
much
is
