Students' ability to describe the different types of electromagnetic radiation, including their uses by humans. | 4F- Motion (9-12)#3:…A great variety of radiations are electromagnetic waves: radio waves, microwaves, radiant heat, visible light, ultraviolet radiation, x-rays, and gamma rays. | Standard B: Physical Science- Interactions of Matter and Energy: …Electromagnetic waves include radio waves (the longest wavelength), microwaves, infrared radiation (radiant heat), visible light, ultraviolet radiation, x-rays, and gamma rays. The energy of electromagnetic waves is carried in packets whose magnitude is inversely proportional to the wavelength. |
Students' ability to represent an abstract concept with a physical model/analogy | 11B Models (6-8)#1: Models are often used to think about [things and] processes that happen too slowly, too quickly, or on too small a scale to observe directly… | Unifying Concept and Processes-Evidence, Models, and Explanation: Models are tentative schemes or structures that correspond to real objects, events, or classes of events, and that have explanatory power…Models take many forms, including physical objects… |
Students' ability to critique a model, understanding how it is both like and unlike the real thing. | 11B Models (6-8)#3: Different models can be used to represent the same thing. What kind of a model to use and how complex it should be depends on its purpose. The usefulness of a model may be limited if it is too simple or if it is needlessly complicated. Choosing a useful model is one of the instances in which intuition and creativity come into play in science… | Standard A: Inquiry- Recognize and Analyze Alternative Explanations and Models: …examining logic so as to decide which explanations and models are best… |
