CT.5.1.a. Energy Transfer and Transformations: Sound and light are forms of energy. a) Sound is a form of energy that is produced by the vibration of objects and is transmitted by the vibration of air and objects.
5.1.a.2. Demonstrate how the loudness, pitch and quality/timbre of sound can be varied.
5.1.a.3. Design and conduct investigations to determine factors that affect pitch.
5.1.a.4. Describe the properties of materials that reflect or absorb sound.
5.1.a.5. Construct simple musical instruments (e.g., rubber band guitars, drums, etc.) that produce sounds with various pitches, volume and timbres.
CT.5.1b. Energy Transfer and Transformations: Sound and light are forms of energy. b) Light is a form of energy that travels in a straight line and can be reflected by a mirror, refracted by a lens, or absorbed by objects.
5.1.b.2. Investigate how light is refracted as it passes through a lens or through one transparent material to another.
5.1.b.7. Determine whether a material is opaque, transparent or translucent based on how light passes through it.
CT.5.4. Science and Technology in Society: Humans have the capacity to build and use tools to advance the quality of their lives. a) Advances in technology allow individuals to acquire new information about the world.
5.4.1. Generalize that optical tools, such as binoculars, telescopes, eyeglasses or periscopes, change the path of light by reflecting or refracting it.
5.4.4. Design and conduct simple investigations to determine how the shape of a lens or mirror (concave, convex, flat) affects the direction in which light rays travel.
