8.2: Physics 3 Dimensions & Progressions

Unit 1

STANDARD ● 8.2.4 Use computational thinking to describe a simple model for waves that shows the pattern of wave amplitude being related to wave energy. Emphasize describing waves with both quantitative and qualitative thinking. Examples could include using graphs, charts, computer simulations, or physical models to demonstrate amplitude and energy correlation. (MS-PS4-1)

CONCEPTS

SKILLS

● Kinetic energy ● Energy transfer

● Engage in argument ● Support claim

LEARNING PROGRESSIONS

● A simple wave has a repeating pattern ● The repeating pattern has specifc wavelengths, frequencies, and amplitude. ● A sound wave needs a medium through which it is transmitted

VOCABULARY ● Speed ● Force

● Proportional ● Soundwave ● Wavelength

● Frequency ● Medium ● Amplitude

● Kinetic Energy

POSSIBLE PHENOMENA ● The higher a rock is dropped from, bigger waves will be created. ● A big wave at the beach can knock me down, but a small wave can’t. ● It takes more energy to yell than it does to whisper. ● If I turn the volume on my phone all the way up to watch videos, the battery will wear down faster. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ● I can use computational thinking to describe the differences between waves and explain how amplitude is related to wave energy. ○ Language Supports: ■ Abstract nouns to introduce concepts (effect, relationship) ■ Connectors to link clauses (as a result of, therefore, instead, however, on the other hand) ■ Clause types to express causality (if/then) ■ Connectors to signal time (therefore, consequently, as a result of, because)
