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.
3.1.5 Observe and describe how light is absorbed, changes its direction, is reflected back and passes through objects. Observe and describe that a shadow results when light cannot pass through an object.
3.1.6 Describe evidence to support the idea that light and sound are forms of energy.
2 Earth Science
Observe, describe and identify rocks and minerals by their specific properties.
3.2.1 Examine the physical properties of rock samples and sort them into categories based on size using simple tools such as sieves.
