Ben Franklin came to visit the second, third and fourth grade students of McKenzie and introduced students to the simple wonder of static electricity and the basic scientific process.
Students observed demonstrations that blend colors to produce white light and that separate white light into colors. Experiments with prisms and diffraction lenses gave students the opportunity to explore the color spectrum of various light sources. A chromatography activity demonstrated separating printed colors on filter paper. Students investigated ultraviolet light and the world through the eyes of an animal. The students made their own color wheel to take home.
Mad Science led the second graders on an exploration of how sounds are created and transmitted through a solid, liquid and gas. Concepts like vibration, frequency (pitch), sound waves, anatomy of the ear and how we hear were addressed. Students experimented with the vibrations produced by tuning forks, and explore how the vibrations of sound jump into the inner ear as they travel through the air as sound waves. Students used Mad Science equipment to “hear” sound vibrations through their fingers, and everyone made a pan flute that demonstrates different pitches.
