Specific skills and knowledge demonstrated by the task:
|
Alignment with Project 2061 Benchmarks for Science Literacy
|
Alignment with National Science Education Standards
|
|
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…
