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 instructional activity. It can certainly enrich a social studies instructional activity on how lighthouses spurred the growth of the shipping industry, or it can be an addition to your physical science instructional activity on lenses and light.
