What were some new learnings, something that you may have already known, or some questions you still have? I never really thought about how important the study of waves is! By understanding wave properties and the interactions of electromagnetic radiation with matter, scientists and engineers can design systems for transferring information across long distances, storing information, and investigating nature on many scales—some of them far beyond direct human perception.
<br/>What preconceptions do you anticipate your students will have about topics found in this standard? Some preconceptions include: 1. When a colored light illuminates a colored object, the color of the light mixes with the color of the object. 2. The eye is the only organ for sight; the brain is only for thinking. 3. The eye receives upright images. 4. The lens is the only part of the eye responsible for focusing light. 5.The lens forms an image (picture) on the retina. The brain then “looks” at this image and that is how we see.
<br/>What are some ways you plan on addressing these preconceptions? I plan to address these preconceptions using phenomena such as “Blue Birds aren’t really blue” followed by investigations and class discussions.

What were some new learnings, something that you may have already known, or some questions you still have? I was interested in the idea that waves pass through each other. Although this makes complete sense from observations like ripples in the water and echoes and being able to hear different sounds ta the same time, I really hadn’t thought about it before.
<br/><br/>What preconceptions do you anticipate your students will have about topics found in this standard? All waves must have a medium that they are traveling through. Waves collide and are destroyed. Waves lose energy. Waves can’t travel through everything.
<br/><br/>What are some ways you plan on addressing these preconceptions? I would have the students experiment using sound and transferring the waves through different medium. We would also look at light as it travels through space, air, clouds, etc. Tying in with previous learnings about sound transmission, we will take a deeper look at the “phones’ that we made.

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.
<br/><br/>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.

<br/>What are some ways you plan on addressing these preconceptions? - Showing students what types of energy is used for the waves.
