Rationale
• The following benchmark was chosen
because of the preciseness with which it
matched the nature of our topic
• Our group developed this presentation to
provide secondary teachers with excellent
electronic resources from which to develop
a comprehensive lesson on volcanoes
SC.D.1.4.2 -
knows that the solid crust of Earth consists of slowmoving, separate plates that float on a denser, molten layer of Earth and
that these plates interact with each other, changing the Earth’s surface in
many ways (e.g., forming mountain ranges and rift valleys, causing
earthquake and volcanic activity, and forming undersea mountains that
can become ocean islands).
Connections
• Science – Scientists gain a greater understanding
of the forces that shape our earth through their
study of the causes and consequences of volcanic
activity.
• Technology – The study of volcanoes has led not
only to more accurate prediction of eruptions but
also to the use of thermodynamics as an alternate
energy source. Improved devices that measure
seismic occurrences are also being used to
discover new petroleum reserves.
More Connections
• Society – By understanding the nature of
volcanoes, scientists are better able to predict
possible eruptions, saving human life and property.
They are also able to determine the effects these
eruptions may have on future weather conditions
and changes in climate.

What to do during an eruption…
RUN AWAY, RUN AWAY!!
Monitoring Volcanoes
• to obtain additional
scientific knowledge
on volcanoes
• help predict eruptions
in an attempt minimize
risk to population
