Navigational Aids Used by Great Lakes Ships

Learners examine a fresnel lens and compare it to simple concave and convex lenses. They measure its focal length and then discuss why this type of lens is useful in a lighthouse system. That is about all there is to this lesson. It can certainly enrich a social studies lesson on how lighthouses spurred the growth of the shipping industry, or it can be an addition to your physical science lesson on lenses and light.
