This
activity
will
help
students
to
have
a
better
understanding
of
the
basic
principles
used
to
determine
the
age
of
rocks
and
fossils.
It
consists
of
several
parts:
to
have
students
determine
relative
age
of
a
geologically
complex
area,
to
familiarize
students
with
the
concept
of
half-life
in
radioactive
decay,
to
have
students
see
that
individual
runs
of
statistical
processes
are
less
predictable

This
lesson
shows
students
that
age-dating
rocks
involves
counting
atoms
and
comparing
the
counts.
Students
use
simulated
rock
samples,
which
show
a
highly
magnified
selection
of
128
atoms,
each
sample
with
a
different
proportion
of
the
atoms
of
two
different
elements:
a
parent
radioisotope,
and
its
daughter
product.
By
counting
the
parent
radioactive
atoms
and
knowing
the
half-life
of
those
atoms,
...

In
this
lab
activity
using
M&M
candy,
students
will
explore
the
concepts
of
radioactive
decay
and
dating.
Students
generate
a
radioactive
decay
table
to
simplify
the
math,
use
their
data
to
plot
a
decay
graph,
develop
the
concept
of
half-life,
and
then
use
the
graph
to
find
the
age
of
a
mummified
seal
in
Wright
Valley,
Antarctica.
In
a
follow-up
exercise,
students
will
solve
a
mysterious
Arctic
...
