In
this
activity
students
use
the
alphabet
stone
(called
the
Futhark),
to
assign
an
English
letter
to
each
of
the
symbols
in
a
string
of
runes.
They
will
then
uncover
a
message
about
the
Northern
Lights,
in
the
form
of
a
question,
which
they
will
have
to
answer.
In
addition,
they
will
discover
that
the
Vikings
knew
about
the
Northern
Lights.
In
their
mythology,
the
colorful
auroral
archways
were
identified

In
this
activity
students
bring
in
samples
of
local
rocks
for
the
teacher
to
cut
in
half
with
a
diamond
saw.
Students
then
analyze
and
report
on
the
grain
relationships
within
the
rock.
As
a
follow-up
activity
students
can
exchange
rocks,
write
an
analysis
of
the
sawn
sample,
and
compare
notes.
In
cases
where
disagreements
cannot
be
resolved,
the
teacher
should
offer
a
third
analysis
of
the
sample.

Students
will
participate
in
a
modeling
activity
that
simulates
the
cyclical
role
of
experimental
and
theoretical
science.
Initially,
the
students
will
measure
the
mass
of
popcorn
kernels.
While
the
mass
of
the
kernels
are
determined,
students
will
also
make
predictions
of
the
mass
of
the
kernels
after
they
are
popped.
After
the
popcorn
is
popped,
the
mass
of
the
popcorn
is
measured.
Data
is
shared

This
project
establishes
an
educational
and
scientific
partnership
between
elementary

school
students,
a
regional
university,
and
a
national
scientific
laboratory,
all
focusing
on
the
science
and
mathematics
of
snowflake
formation.
Students
will
conduct
fieldwork
investigations
using
portable
digital

In
this
activity,
air
with
increased
concentrations
of
carbon
dioxide
is
produced
and
the
rate
of
heat
loss
of
that
air
is
compared
to
today's
normal
air.
This
is
used
to
help
demonstrate
the
environmental
and
economic
effects
of
increased
carbon
dioxide
(CO2)
content
in
the
atmosphere.
It
tests
the
claim
that
the
Earth's

This
experiment
uses
inexpensive
and
easy-to-find
items
to
demonstrate
how
hot
water
behaves
in
a
body
of
cold
water.
Working
in
groups
of
four,
students
can
complete
the
experiment
in
a
single
class
period.
The
printable
six-page
handout
includes
a
series
of
inquiry-based
questions
to
get
students
thinking
about
how
cold
and
hot
air
and
water
interact,
detailed
experiment
directions,
and

In
this
lesson,
students
set
up
working
models
demonstrating
lake
turnover
(vertical
movement
of
water
and
nutrients
within
a
lake,
caused
by
changes
in
water
density)
and
the
formation
of
deep
water
masses
in
the
oceans.
The
students
will
use
two
water
samples
at
different
temperatures,
with
different
colors
of
food
coloring
added.
These
water
samples
are
poured
into
a
tank
to
produce
stratification.
