Ships
travelling
between
Lake
Ontario
and
Lake
Erie
use
the
Welland
Canal.
Beginning
with
a
conversation
between
characters
Mathise,
Geo,
and
Trig,
they
explain
how
a
lock
in
the
canal
operates
by
gravity
alone,
without
pumps.
The
characters
use
mathematics
to
solve
problems
such
as
how
long
the
locks
take
to
fill
and
how
to
express
the
volume
and
flow
of
water
in
more
common
terms
(bathtubs
of
water

The
purpose
of
this
resource
is
to
learn
how
to
estimate
data
results
in
order
to
minimize
errors
in
reading

recording
data.
Students
participate
in
a
game
in
which
they
collect
data
using
various
instruments
and
calculations
and
then
try
to
fool
other

Working
in

They
estimate
the

In this activity, students build an edible aquifer using ice cream, food coloring, and other ingredients to represent the various layers. They will learn about groundwater, water tables, confining layers, contamination, and recharge. A link to a glossary of groundwater terms is provided.

Flowing
water
from
rivers
and
streams
is
a
valuable
and
plentiful
energy
resource
that
people
learned
to
use
centuries
ago
to
operate
the
machinery
that
was
important
to
their
livelihoods.
This
page
features
diagrams
(some

that
show
the
three
main
principles
of
water;

The
purpose
of
this
activity
is
to
observe
the
type
and
cover
of
clouds
including
contrails.
Students
observe
which

types
of
clouds
and
how
many
of
three
types
of
contrails
are
visible
and
how
much
of
the
sky
is
covered
by
clouds
(other
than
contrails)
and
how
much
is
covered
by
contrails.
Intended
outcomes
are
that

The
purpose
of
this
resource
is
to
introduce
students
to
the
importance
of
soil.
In
the
first
activity,
students
generate
a
list
of
why
soils
are
important.
In
the
second
activity,
students
are
asked
to
describe
the
five
factors
that
form
a
unique
soil
profile
and
to
explore
these
concepts.
In
the
third
activity,
students
are
shown
a

of
how
much

there
is
on
Earth
that

The purpose of this resource is to develop an understanding of the relationship between budburst and the environment and to help students recognize actual budburst when they are doing the Green-Up protocol. Students will do simple explorations to observe the relationship between budburst and temperature. This is a winter or dry season activity to be done prior to green-up observations.
