When
it
was
decided
that
the
Gottesman
Hall
of
Planet
Earth
in
the
American
Museum
of
Natural
History
would
be
designed
around
huge
rock
samples,
one
obvious
choice
for
the
volcano
section
of
the
hall
was
obsidian.
This
site
tells
the
story
of
the
quest
of
Dr.
Ro
Kinzler
for
that
sample
and
the
local
man
named
Jeff
Dinnel,
a
self-taught
naturalist,
who
had
assembled
a
collection
of
rocks,
bones,
and

this
site,
Illustrations
from
the
Hall
of
Planet
Earth,
has
two
informative
overviews
about
ice
ages
and
Earth's
orbit.
In
another
section,
Gowganda
Conglomerate
from

Supergroup
in
the
Hall
of
Planet
Earth,
there
are
two
images
of
this
rock
formed
from
the
debris
of
ancient
glaciers,

This
activity
uses
logarithmic
plotting
to
show
the
power
of
a
straight
line
in
mathematics,
science,
and
engineering.
Students
will
use
the
slopes
of
various
curves
plotted
on
log-log
graph
paper
to
classify
stellar
objects
as
binary
stars,
supernovae,
or
active
galaxies.
The
data
used
in
this
lesson
were
obtained
from
X-ray
astronomy
satellites.

This
online
meteorology
course
is
designed
to
help
students
become
aware

aspects
of
severe
local
storms.
It
centers
on
hurricanes
and
tornadic
supercell
thunderstorms.
The
course
is
also
designed
to
expose
students
to
procedural
aspects
of
scientific
research
(the
scientific
method).

These
are
the
teaching
notes
for
a
case
study
that
deals
with
the
question
"Was
there
past
life
on
Mars?"
This
issue
received
attention
in
1996
when
a
group
of
scientists
associated
with
the
National
Aeronautics
and
Space
Administration
(NASA)
held
a
press
conference
where
they
revealed
evidence
favoring
the
presence
of
life
on
Mars
billions
of
years
ago.
These
findings
were
publicized
days
in
advance

This
lesson
plan
is
part
of
the
DiscoverySchool.com
lesson
plan
library
for
grades
9-12.
It
focuses
on
nuclear
reactions,
specifically
fusion
which
creates
energy
on
the
Sun.
Other
types
of
reactions
are
radioactive
decay
and
fission.
Students
look
at
these
different
types
of
reactions
and
learn
about
how
they
happen,
and
specifics
about
the
Sun
such
as
solar
flares,
neutrinos,
and
solar
energy.

This
lesson
is
based
on
an
essay
by
Stephen
Jay
Gould
and
on
the
related
reading
guide.
It
addresses
the
issue
of
cladistics
and
some
of
the
problems
encountered
in
the
science
of
Systematics.
Students
will
learn
that
biological
classification
is
intimately
associated
with
evolution.
They
will
also
learn
that
there
are
many
problems
encountered
in
classification,
providing
evidence
that

In
this
lesson,
students
read
and
discuss
articles
presenting
two
alternative
theories
about
the
extinction
of
dinosaurs.
They
are
encouraged
to
use
the
criteria
that
scientists
use
to
get
the
best
solution.
Students
will
learn
that:
some
evolutionary
change
is
rapid
and
discontinuous;
extinction
plays
in
role
in
macroevolution;
and
scientists
use
specific
criteria
in
deciding
which
theory
is
better.

This article explains why the study of paleontology is important to science education. Topics include the basic methods and goals of paleontology, how it is relevant to the modern world, and why paleontology can be useful in keeping students involved and interested in science. Links to additional information are embedded in the text.
