has
students
use
simple
sine
waves
to
explore
constructive
and
destructive
interference
in
seismic
waves.
After
plotting
the
summative
points
of
two
sine
waves,
students
connect
the
points
to
create
the
resulting
complex
wave.
Once
they
have
successfully
drawn
their
complex
wave,
they
will
answer
the
questions
listed
on
the
student
handout.

This lesson reviews clouds and uses fractions to describe cloud coverage, demonstrating how math and science work together. By using math and science to describe clouds, the lesson provides students with several means of communication (fractions and meteorological terms) to describe a meteorological situation.
