In this science unit, students will investigate light and sound, including vibration from sound waves and the effect of different materials on the path of a beam of light. The students will use a design process to sketch, build, test, and reflect on a device that uses light or sound to communicate over a distance.

Key Terms
- Color: The way that objects appear different (brown, red, yellow, blue, etc.) because of light reflected by the object. The color white is made up of many different wavelengths of light.
- Communicate: To exchange ideas or information.
- Design Process: A step by step way to solve problems.
- Engineer: A person who is trained to use technology, mathematics, and science to solve problems.
- Engineering: The use of technology, mathematics, and science to solve problems.
- Light: The form of energy that makes it possible to see things; the brightness produced by the sun, by fire, a lamp, etc.
- Reflection: The return of light or sound waves from a surface.
- Refraction: The bending of rays or waves of light.
- Sketch: A drawing showing the main features of an object.
- Sound: Something that can be heard.
- Vibration: The process of moving back and forth rapidly.
