This
lesson
provides
a
real-sense
time
scale
experience
to
better
visualize
the
vast
extent
of
geological
time.
Using
familiar
linear
analogs,
students
come
to
realize
that
the
five
main
classes
of
vertebrates
(fishes,
amphibians,
reptiles,
mammals
and
birds)
each
emerged
several
tens
of
millions
of
years
apart,
over
the
past
500
million
years.
Students
also
discover
when

earliest
fossils
of

This
module
consists
of
five
lessons
in
which
students
work
backwards
from
the
present,
investigating
events
in
the
history
of
a
rock
as
far
back
as
its
formation.
They
should
be
able
to
demonstrate
the
knowledge
that
Earth
processes
create
a
change
in
the
Earth's
surface
over
time;
transfer
this
knowledge
and
apply
it
to
modern
examples;
analyze
their
surrounding
geography
and
determine
which
Earth

Students
write
a
short
essay
using
relative
age
principles
to
describe
a
fictional
set
of
geologic
events
and
processes
(specified
in
the
exercise)
that
occur
in
a
hypothetical
area.
The
essay
is
used
to
develop
a
geologic
profile,
and
then
it
is
given
to
another
student
who
is
tasked
with
producing
the
correct
geologic
profile
(as
a
quiz),
based
on
the
essay
information.

In
this
activity,
students
are
assigned
a
geologic
profile
based
on
a
set
of
rock
samples
and
are
asked
to
arrange
the
samples
from
oldest
to
youngest.
They
then
identify
each
rock
type
and
record
their
observations
of
what
processes
might
have
formed
it,
what
type
of
sediment
it
is
made
of,
what
sort
of
environment
it
might
have
formed
in,
and
what
agents
of
erosion
or
deposition
might
have
been

This
unit
introduces
students
to
the
development
of
the
theory
of
continental
drift.
They
will
examine
the
early
work
of
Alfred
Wegener
and
Alexander
DuToit,
investigate
lines
of
evidence
that
resulted
in
the
development
of
the
theory,
and
learn
about
the
final
lines
of
evidence
that
resulted
in
the
theory's
acceptance.
There
is
a
set
of
activities
in
which
the
students
construct
a
map
of
Pangea
using

Earth
science
courses
typically
include
the
concept
of
geological
time.
The
authors
of
this
study
attempt
to
move
past
traditional
assessment
practices
and
develop
a
formative
assessment
of
students'
understanding
of
the
construction
of
the
geologic
time
scale
and
how
it
is
interpreted.
Through
this
approach
students
are
challenged
to
conceptualize
the
geologic
time
scale
by
comparing
it
to
a
student-produced

This
article
presents
an
idea
for
a
classroom
activity
that
is
intended
to
replace
some
of
the
lectures
that
would
ordinarily
be
necessary
in
a
survey
of
Earth
history
over
geologic
time.
Students
take
the
lecturer's
place
in
front
of
the
class
and
present
some
of
the
material
to
their
colleagues.
They
work
in
groups
on
a
single
era
or
period.
Each
student
plays
the
role
of
an
expert
(such
as
an
oceanographer)
