Describe how the colors of available light sources and the bending of light waves determine what we see.
Determine the effect of placing objects made with different materials (transparent, translucent, opaque, and reflective) in the path of a beam of light.
Use a model to describe how light is required to make objects visible. Summarize how Illumination could be from an external light source or by an object giving off its own light.
Use a variety of materials to produce sounds of different pitch and volume.
Investigate how light travels and is influenced by different types of materials and surfaces.
