Activities involving motion, lenses and a tour of the observatory
A concave lens form is explored using the three-light source of a Rive light box. Intriguing reflection effects result when a right-angle prism is explored with a three-light source. A lens held over print. Rive light box through prism. Rive light paths with two prisms in the dark. Student holding lenses. Marks of a ball dropped on carbon paper pressed onto white paper. A balls bouncing marks recorded via carbon paper. A ball on a multi curved ramp. Lighting a ball rolling on a multi curved ramp. A reflector telescope at the observatory like the one we used.
