Statistics
play
a
vital
role
in
the
scientific
enterprise.
This
activity
provides
background
information
and
tutorials
on
basic
statistics
(mean,
median,
standard
deviation,
etc.)
used
in
science.
Topics
include
descriptive
statistics
(measures
of
central
tendency
and
dispersion)
and
presenting
data
(tables,
figures,
and
graphs).
Sample
datasets
from

There
are
two
ways
to
reduce
net
emissions
of
carbon
dioxide:
limit
how
much
carbon
dioxide
is
emitted
into
the
atmosphere
as
we
burn
fossil
fuels,
or
increase
the
rate
at
which
it
is
absorbed.
In
this
lesson,
discussion
topics
include
the
Kyoto
Protocol
and
the
use
of
carbon
credits
to
reduce
emissions
of
carbon
dioxide
into
the
atmosphere.
Students
can
listen
to
a
National
Public
Radio

This
lesson
provides
an
overview
of
water
use
in
the
industrialized
world,
including
a
discussion
of
the
increasing
need
for
conservation
as
populations
grow
and
water
supplies
stay
roughly
constant.
Users
can
listen
to
a
National
Public
Radio
(NPR)
show
that
discusses
water-use
restrictions
that
have
been
enacted
in

The
amount
of
energy
used
in
a
home
is
greatly
impacted
by
the
type
of
materials
used
in
constructing
the
home.
In
particular,
the
thermal
conductivity
of
the
materials
will
affect
how
quickly
heat
is
allowed
to
enter
or
leave
the
home.
In
this
hands-on
activity,
students
will
measure
the
ability
of
various
materials
to
resist
heat
flow
(R-factor)
by
placing
a
light
bulb
inside
boxes
made
of
the
materials

This
lesson
provides
an
introduction
to
the
occurrence
and
possible
risks
of
household
chemical
products.
Topics
include
some
basic
chemistry
(how
elements
combine
to
form
compounds),
how
chemicals
are
classified,
and
the
idea
of
natural,
as
opposed
to
synthetic,
chemicals.
The
lesson
includes
an
activity
in
which
students
take
an
inventory
of
chemical
products
in
their
homes
and
research

This
lesson
discusses
population
growth,
both
in
the
United
States
and
in
the
world.
Topics
include
factors
that
influence
population
growth,
such
as
government
policy,
religion,
education
or
economic
levels,
energy
use
per
capita,
and
whether
a
country
is
agrarian
or
industrial.
The
lesson
includes
an
activity
in
which
students
research
an
online
resource
on
population
growth
and
answer
questions

This
lesson
provides
an
introduction
to
the
use
of
natural
gas
as
an
energy
source.
Topics
include
its
advantages
(cleanliness,
fewer
carbon
emissions),
disadvantages
(difficulty
in
transport
and
storage),
sources,
and
usage.
There
is
also
a
discussion
of
the
creation
and
production
of
natural
gas,
the
United
States'
production
and
reserves,
and
some

High
levels
of
ultraviolet
light
can
be
harmful
to
many
biological
systems,
as
this
higher
energy
radiation
has
a
mutagenic
effect
on
plant
and
animal
cells.
This
activity
studies
the
relationship
between
the
amount
of
ultraviolet
(UV)
radiation
that
gets
to
Earth's
surface
and
the
amount
of
stratospheric
ozone
overhead.
Users
plot
remote
sensing
data
from
the
NASA
Total
Ozone

to
reinforce
the
importance
of
Earth's
atmosphere
to
living
organisms.
