Work independently and collaboratively to solve problems and accomplish goals.
-
Communicate information clearly and effectively using a variety of tools/media in varied contexts for a variety of purposes.
-
Demonstrate innovation, flexibility and adaptability in thinking patterns, work habits, and working/learning conditions.
-
Effectively apply the analysis, synthesis, and evaluative processes that enable productive problem solving.
-
Value and demonstrate personal responsibility, character, cultural understanding, and ethical behavior.

Understandings
Students will understand…
-
The wavelength of a wave is inversely proportional to its frequency.
-
The amplitude of a sound wave correlates to the volume, the amplitude of a matter wave correlates to the height of the wave, the amplitude of a light wave correlates to the brightness of the light.
-
The frequency of sound wave correlates to the pitch of the sound.
-
The frequency of a wave is directly proportional to the energy of the wave.
-
The energy of a wave is proportional to the square of the amplitude.
-
A change in a wave variable produces a change in the energy of the wave.
-
Matter waves need a material for movement, light waves do not require a medium for travel.
-
The pro's and con's of analog and digital signals.
|
Essential Questions
Students will keep considering…
-
What are the characteristics of waves and how can they be used?
-
Why are materials with certain properties well suited for particular functions?
-
Why is the digital transmission of signals more reliable than the analog transmission of signals?

Acquisition
|
|
Students will know…
-
A wave is a series of pulses created from a disturbance.
-
The amplitude, frequency, wavelength of a wave.
-
Matter wave.
-
Light wave.
-
Light is part of the electromagnetic spectrum.
-
Reflection is the bouncing back of waves from a surface.
-
Absorption occurs when a substance absorbs the wave.
-
Refraction occurs when a wave crosses boundary into a less dense material and bends.
-
Transmittance occurs when the wave goes through a medium.
-
Analog and Digital signals.
|
Students will be skilled at…
-
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
-
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
-
Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
