The
purpose
of
this
activity
is
to
measure
relative
humidity
using
both
a
sling
psychrometer
and
a
digital
hygrometer.
Intended
outcomes
are
that
students
learn
to
quantify
humidity
and
that
there
is
a
limit
to
the
amount
of
water
vapor
that
the
air
can
hold.
Students
gain
insight
into
why
rain
drops
and
snow
flakes
form
and
why
there
is
precipitation.

The
purpose
of
this
activity
is
to
introduce
students
to
visualizations
as
a
tool
for
scientific
problem-solving,
using
elevation
and
temperature
as
an
example.
Students
color
in
visualizations
of
elevation
and
temperature
so
that
important
patterns
in
the
data
become
evident.
The
relationship
between
the
two
quantities
is
studied
by
using
them
to
compute
the
lapse
rate,
the
rate
at
which

The
purpose
of
this
activity
is
to
measure
air
(and
optionally
soil)
temperature
within
one
hour
of
solar
noon
and
the
maximum
and
minimum
air
temperatures
for
the
previous
24
hours.
Intended
outcomes
are
that
students
will
learn
to
read
minimum,
maximum,
and
current
temperatures
using
a
U-shaped
thermometer,
understand
diurnal
and
annual
temperature
variations,
and
recognize
factors
that
influence

The
purpose
of
this
activity
is
to
construct
a
model
that
will
provide
students
with
a
visual
representation
of
parts
per
billion.
Students
work
in
teams
to
construct
cubes
of
different
volumes
and
to
compare
them
to
get
a
feel
for
parts
per
million
by
volume
and
parts
per
billion
by
volume.
The
intended
outcome
is
that
students
gain
a
feeling
for
the
small
quantities
of
gases,
such
as
ozone,
present

The
purpose
of
this
activity
is
to
measure
ozone
concentrations
at
ground
level.
Students
deploy
a
strip
of
paper
that
changes
color
in
the
presence
of
ozone.
They
use
an
ozone
reader
to
determine
the
amount
of
ozone
in
ppb
as
indicated
by
the
color
change
of
the
paper
strip.
Intended
outcomes
are
that
students
will
learn
to
measure
the
concentrations
of
ground-level
ozone
in
the
atmosphere
and
to

The purpose of this resource is to teach students about the acidity levels of liquids and other substances around their school so they understand what pH levels tell us about the environment. Students will create mixtures of water samples, soil samples, plants and other natural materials to better understand the importance of pH levels.

The
purpose
of
this
activity
is
to
determine
the
amount
of
moisture
input
to
the
local
environment
by
measuring
rain
and
snowfall
and
to
measure
the
pH
of
precipitation.
To
do
so
students
use
a
rain
gauge
and
a
snowboard
to
measure
the
daily
amount
of
precipitation.
Special
pH
measuring
techniques
for
precipitation
are
used
to
determine
the
pH
of
rain
and
melted
snow.
Intended
outcomes
are
that
