Lesson Plan

Sentinels of our Shores


How did a young United States defend its greatest port, New York City? Sentinels of Our Shores takes upper elementary students back to the year 1846, when war clouds gathered over the US, Canada and Mexico.

First, student "cadets" conduct hands-on scientific experiments with our own unique air-powered cannon. How do changing variables, such as the angle or air pressure, affect the range of the cannon? Cadets then decide where to build forts by reading historic documents, including maps.
