8.2: Physics 3 Dimensions & Progressions

Unit 1

Objective

Overview

Materials

●​ Students will re-watch a video and explain how wave height is related to energy level. Connection to amplitude, frequency, wavelength should be made. ●​ Students should be able to answer the following questions: What makes some sounds louder than others? Lights brighter than others? ●​ The structure of a wave affects its ability to be reflected, absorbed, or transmitted through mediums. Have students perform one of the following experiments or demo it. Ask students what they think is happening. ​ How are reflection, absorption and transmission of light

●​ Tsunami Survival Story ●​ Tsunami Survival Video (with analysis questions)

●​ I can draw a model that shows the patterns of

how a wave’s amplitude is related to the energy of the wave

8.2.5 Phenomena: Disappearing Trick

Objective

Overview

Materials

●​ I can create a hypothesis about how light travels through different materials.

●​ Light’s behavior through water Video ●​ Disappearing coin trick ●​ Disappearing glass trick

waves through a medium involved in the creation of a rainbow?

Activity: PhET Simulation - Waves on a String

Objective

Overview

Materials

●​ Students will use the two phet simulations to gather evidence of wave behavior as it is reflected, absorbed, and transmitted through various materials.

●​ Waves on a String PhET ●​ Longitudinal and Transverse wave motion Longitudinal and Transverse Wave Motion Video

●​ I can create a model of a mechanical wave that explains how they are reflected, absorbed and transmitted through various materials
