Brief Summary of Unit
Students will understand that:
• All waves transfer energy without the movement of matter
• Waves travel at different speeds according to the density of a medium
• Amplitude determines the amount of energy a wave carries
• Wavelength and frequency are related
• How do waves transfer energy?
• How are frequency and wavelength related?
• How are amplitude and energy related?
• How are waves generated?
• What is the difference between and transverse and longitudinal wave?
• How do the particles in ocean waves move?
• What are some ways to measure and compare waves?
• How can you calculate the speed of a wave?
• Why does the pitch of an ambulance siren change as the ambulance rushes past you?
• How do waves behave when they hit a boundary, when they pass around an edge or opening, and when they pass from one medium to another?
• What happens when two or more waves are in the same location?
• How does a wave affect the medium in which it travels?
• What are the characteristics of sound waves?
• How do musical instruments make sound?
• How do ears help humans hear sound waves?
• How are the reflections of sound waves used?
• How do scientific models describe light?
• What does the electromagnetic spectrum consist of?
• How do objects interact with incoming light?
• How can you see an image in a mirror?
• Why do we see colors?
• What happens to light when it passes from one medium to another medium?
• What happens when light passes through a lens?
• How can a prism separate white light into colors?
