Central
to
good
science
are
accurate
observations,
testable
hypotheses,
well-designed
experiments
or
other
tests,
and
reasonable
data
analyses.
The
purpose
of
this
activity
is
to
introduce
the
basics
of
designing
and
analyzing
experiments.
This
is
accomplished
by
using
a
computer
simulation
that
involves
the
real-world
industry
of
farming
fish.
The
two
laboratory
exercises
include
further
steps

This
is
the
first
part
of
a
two-part
exercise
in
which
students
perform
an
audit
and
analysis
of
energy
consumption
in
their
homes.
This
part
provides
an
introduction
to
the
uses
of
energy
in
our
homes.
Topics
include
major
uses
in
the
home
(heating,
air
conditioning,
etc.),
sources
of
energy
(fossil
fuels),
and
uses
in
the
United
States
(industry,
transportation,
etc.).

This
capstone
activity
uses
the
results
of
the
Home
Energy
Audit
and
the
Home
Energy
Analysis
activities
to
investigate
how
changes
in
lifestyle
affect
the
amount
of
energy
used
in
the
home.
Students
will
listen
to
a
National
Public
Radio
show
that
discusses
the
energy
efficiency
of
home
appliances
and
their
sales
to
see
if
any
of
the
issues
mentioned
relate
to
their
willingness
to
make
similar
investments.

This
lesson
summarizes
our
dependency
upon
fossil
fuels,
pointing
out
that
there
are
very
few
aspects
of
our
daily
life
that
are
not
impacted
by
their
use.
The
discussion
centers
around
whether
these
fuels
could
be
replaced
and
makes
the
point
that
there
is
a
significant
percentage
of
them
which
is
used
to
manufacture
products
and
is
not
simply
burned
for
energy.

This
is
the
culminating
activity
in
the
series
of
lessons
on
renewable
energy.
It
serves
to
reinforce
the
idea
that
renewable
sources
of
energy
are
necessary
for
a
sustainable
fuure,
and
to
discuss
some
of
the
present
impacts
and
potential
drawbacks
to
renewable
energy.
In
the
activity,
sudents
will
use
online
resources
to
research
their

The
transport
and
transformation
of
substances
in
the
environment
are
known
collectively
as
biogeochemical
cycles.
These
global
cycles
involve
the
circulation
of
elements
and
nutrients
that
sustain
both
the
biological
and
physical
aspects
of
the
environment.
As
an
example,
this
discussion
centers
around
the
carbon
cycle
and
how
carbon
is
sequestered
in
trees.
Students
will
perform

in
the
United
States,
due
primarily
to
the
size
and
composition
of
the
American
diet.
Discussion
topics
include
lack
of
exercise,
changes
in
calorie
intake
over
time,
and
environmental
impacts
of
these
increases
in
consumption.
Each
student
will
particpate
in
an
activity
in
which
they
investigate
how
their
own
diets
affect
the
