This Refraction B2—When is Light Reflected Internally? lesson plan also includes:

Physics is phun in this instructional activity. Young physicists use a lightbox to test how and where light is refracted and reflected as it travels through transparent materials. Angles of incidence and refraction, sine of both angles, and the ratio are all figured in the included worksheet.
