8.2: Physics 3 Dimensions & Progressions

Unit 1

8.2.5 Phenomena: Disappearing Trick

Objective

Overview

Materials

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

● The structure of a wave affects its ability to be refected, absorbed, or transmitted through mediums. Have students perform one of the following experiments or demo it. Ask students what they think is happening. Howare refection, absorption and transmission of light waves through a medium involved in the creation of a rainbow?

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

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 refected, 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 refected, absorbed and transmitted through various materials referencing models in the explanation.

●

Students will list claims and then support each statement with evidence from the simulation.

Activity: Light through a Prism

Objective

Overview

Materials

● Students experiment with a fashlight and a prism. They will observe the visible light spectrum and draw the set-up and their fndings.

● prisms and fashlights

● I can create a model of a light wave that explains how they refected, absorbed and transmitted through various materials referencing models in the explanation.
