Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light.
In the last unit, students explored the relationship between vibrations and sound. In this unit, students continue to explore the phenomena of human senses, focusing on how objects can be seen when they are illuminated by a source of light, and how light passes through opaque, transparent, and translucent materials differently. Students then investigate how a beam of light changes when it hits a mirror.
