What were some new learnings, something that you may have already known, or some questions you still have? - When a wave passes an object that is small compared with its wavelength, the wave is not much affected; for this reason, some things are too small to see with visible light, which is a wave phenomenon with a limited range of wavelengths corresponding to each color. Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; it does not move in the direction of the wave—observe, for example, a bobbing cork or seabird—except when the water meets the beach. Sound can make matter vibrate, and vibrating matter can make sound.
What preconceptions do you anticipate your students will have about topics found in this standard? - A common misconception (wrong idea) regarding waves is that a wave involves the movement of matter from the source to other parts of a medium. Waves involve the transport of energy, not the transport of matter.
What are some ways you plan on addressing these preconceptions? - Showing students what types of energy is used for the waves.
