  • Observe and describe how sound is produced by vibrations.

    • 3.1.1 Generate sounds using different materials, objects and techniques. Record the sounds and then discuss and share the results.

    • 3.1.2 Investigate how the loudness and pitch of sound changes when the rate of vibrations changes.

    • 3.1.3 Investigate and recognize that sound moves through solids, liquids and gases (e.g., air).

  • Observe and describe how light travels from point to point.

    • 3.1.4 Investigate how light travels through the air and tends to maintain its direction until it interacts with some other object or material.
