This
activity
will
help
students
understand
algal
blooms.
They
will
devise
their
own
experiments
to
test
the
effects
of
nutrients
on
algal
growth,
or
younger
students
may
follow
the
steps
outlined
in
a
sample
activity
which
is
provided.
Students
will
be
reminded
that
they
need
to
have
controls
and
replicates
in
their
experiments.
As
a
result

In
this
activity
students
will
work
in
teams
to
investigate
the
impact
of
an
invasive
species
on
native
species,
using
the
six
classic
steps
for
solving
environmental
problems.
Teams
will
research
a
local
invasive
species
problem,
complete
an
experimental
design
plan,
write
clear
procedures
for
experimentation,
state
expected
results
and
conclusions,
and
work
together

While
engaged
in
this
activity
students
will
explore
phytoplankton,
the

of
tiny
marine
animals,
particularly
krill.
Students
will
prepare
a
hay
infusion
in
two
identical
glass
aquarium
tanks
or
a
1-liter
glass
jar

In
this
laboratory
exercise,
students
will
design
and
conduct
an
experiment
to
evaluate
the
effect
of
the
presence
of
biodegradable
materials
on
dissolved
oxygen
levels.
They
will
come
to
understand
the
effect
of
biodegradable
pollutants
on
water
quality,
design
and
conduct
an
experiment,
interpret
data,
suggest
additional
studies,
and
preform
serial
dilutions.
The
