wave using several models to support the explanation. (qualitative & quantitative)

Activity: Making a Wave Lab

Objective

Overview

Materials

● I can draw a model that shows the patterns of how a wave’s amplitude is related to the energy of thewave. ● I can model and measure wave energy transfer using computer simulations and physical models. (quantitative) ● I can explain how a wave's amplitude is related to the energy of a wave using several

Activity: Gizmo - Waves

Objective

Overview

Materials

● The Waves Gizmo provides an introduction to the basics of transverse and longitudinal wave motion. Using a model

● Gizmo

● I can compare the motions of transverse, longitudinal, and combined waves. Identify and measure the amplitude, wavelength, and frequency of tension, and density of the medium affect wavelength and wave speed. Determine that wave speed is equal to frequency multiplied by wavelength. Explore the factors that affect wave power, including amplitude, frequency, tension, and waves. Explore how amplitude, frequency,

of a spring, students can initiate wave motion by

moving the end of the spring up and down, back and forth, or in circles. Students can observe and measure the amplitude, wavelength, frequency, and speed of waves.
