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.
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.
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.
