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
school.s
computer
and

Students
install
four
temperature
probes;
three
are
placed
in
the
soil
at
three
different
depths
and
one
is
placed
in
an
instrument
shelter.
Students
use
a
data
logger
to
record
readings
from
the
probes
every
15
minutes.
Students
