Science Phenomena: HS Physical Science - Waves and Information (Phys 4.3, 4.4) - A trichroic prism splits light into three beams of light with different wavelengths (or colors). These prisms are used in some video cameras to send different colors of light to different color sensors. The prisms are coated with special coatings to filter and transmit different wavelengths of light. This device could be used to investigate interactions of light with various materials to in increasing complexity K-12.

Science Phenomena: HS Physical Science - Waves and Information - The Rubens' tube was invented by German physicist Heinrich Rubens in 1905. It is a tube that is sealed at both ends in includes a flammable gas like propane. A speaker is attached to one end of the tube so sound waves can be transmitted thought the air/gas mixture. Small holes are drilled in the top of the tube and when the air/gas mixture emerges it creates a flame. As sound is played standing waves are created in the flames that change as the frequency of the waves is changed.
