This comprehensive Middle School NGSS powerpoint pack on MS-PS4 Waves is designed to align with the NGSS Middle School MS-PS4 standards. A visually interactive and editable 65+ slide powerpoint covers the main concepts in the standards.
This presentation covers the following
MS-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.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
Topics covered include:
Introduction to waves
Types of waves
Transverse and longitudinal waves
Compression and rarefraction, seismic waves
Anatomy of a wave
Energy of a wave
Energy is proportional to amplitude
Energy and frequency
Sound waves need a medium
Sound waves - -reflection, echoes, sonar
Sound waves - absorption
Sound waves - interference, constructive, destructive
Sound waves - pitch and frequency
Sound waves - amplitude and loudness
Sound waves - doppler effect
Light travels in straight lines
Light - reflection, refraction
Light - converging, diverging lenses
Light - transmission, transparent, translucent
Light - color, frequency, wavelength
Light - how we see color
Light - amplitude
