In this activity, students calculate the distance from a satellite to a receiving station on Earth. They will learn that radio signals are waves and that wave characteristics can be used to measure properties such as velocity, distance, and time.

In
this
lesson,
younger
students
will
be
introduced
to
the
various
orbital
paths
that
are
used
for
satellites.
Using
a
globe
and
a
satellite
model
or
a
large
picture
of
Earth,
the
teacher
will
introduce
three
types
of
orbital
paths
(polar,
elliptical,
and
geosynchronous).
The
students
should
be
able
to
define
'satellite',
define
the
three
types
of
orbits,
describe
how
satellites
orbit
the
Earth,
and

The EERC at the University of Bristol has developed an Earthquake Engineering Competition that challenges secondary school students to design and make small scale models of buildings that can withstand strong earthquakes. Provided on the website are tips for model design and construction, load testing advice, and a gallery of models organized by various characteristics.

This
teacher's
guide
is
intended
to
provide
suggestions
on
how
to
teach
about
seismic
waves.
It
provides
information
on
the
types
and
properties
of
seismic
waves
and
instructions
for
using
some
simple
materials,
especially
the
'slinky',
to
demonstrate
seismic

characteristics
and
wave
propagation.
These
