2. Today's Targets As a result of today's learning, I will: Deepen my understanding of the DCI – Waves Deepen my understanding of the 3-dimensional teaching/learning of NGSS

3. Agenda Introduction (15) Wave Basics -Transverse(60) Exploring Transverse Waves (45) Wave Basics- Longitudinal (20) Exploring Longitudinal Waves (45) Application (10) Connections (5) Lunch (45) EM Waves (15) Digital Communications (45) Shift to Pedagogy (15) Digital Communication Models in the Classroom (45) Connections (15) Evaluations

4. 4-PS4-1. Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move. [Clarification Statement: Examples of models could include diagrams, analogies, and physical models using wire to illustrate wavelength and amplitude of waves.] [Assessment Boundary: Assessment does not include interference effects, electromagnetic waves, non-periodic waves, or quantitative models of amplitude and wavelength.] 4-PS4-3. Generate and compare multiple solutions that use patterns to transfer information.* [Clarification Statement: Examples of solutions could include drums sending coded information through sound waves, using a grid of 1’s and 0’s representing black and white to send information about a picture, and using Morse code to send text.]

5. MS. Waves and Electromagnetic Radiation Students who demonstrate understanding can: 07-PS4-1. 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. [Clarification Statement: Emphasis is on describing waves with both qualitative and quantitative thinking.] [Assessment Boundary: Assessment does not include electromagnetic waves and is limited to standard repeating waves.] 07-PS4-3. 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. [Clarification Statement: Emphasis is on a basic understanding that waves can be used for communication purposes. Examples could include using fiber optic cable to transmit light pulses, radio wave pulses in wifi devices, and conversion of stored binary patterns to make sound or text on a computer screen.] [Assessment Boundary: Assessment does not include binary counting. Assessment does not include the specific mechanism of any given device.]
