Lesson Plans

Name Description
Battle of the Waves: Sound vs Light

The student will collect, analyze, and interpret data to develop an understanding of how the speeds of sound and electromagnetic waves change through different mediums. Students will simulate and construct and explanation relating to how sound and electromagnetic waves move at different speeds through different mediums.

Wave Speed Through Different Media

Students will use dominoes to model the speed through a mechanical medium in the solid, liquid, and gas phase.

Light Wave Interaction with Matter


Light travels at an incredible fast speed and it allows us to see everything around us. It travels as a wave which interacts with different types of matter in a different way. This lesson is designed for 7th grade students to investigate the different ways in which light waves interact with matter. The type of matter depends on which state the object is in - solid, liquid or gas.
Note: The lesson covers only part of the standard addressed.

Wave Movement, Is it more than just Medium?

Students will discover that light waves and sound waves move at different speeds through different mediums through inquiry, observation and collaboration with peers.

Time needed to complete this lesson:
2 Block Periods
3 Regular Periods

Concert Venue Building Materials MEA

Students will analyze sets of data to determine what construction company proposal would be best suited for building an outdoor concert venue. Students will need to consider sound quality to the concert patrons, disturbances to the local community, and safety.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Why is the sky blue? Students explore how light and sound waves travel in different materials.

Tutorial

Name Description
Speed of Light in Transparent Materials
  • Study the relation between the speed of light and the refractive index of the medium it passes through.
  • Choose from a collection of materials with known refractive indices and obtain the speed of light as it passes through.
  • Learn why light-years are used as an astronomical measurement of distance.

Virtual Manipulatives

Name Description
Refraction of Light

This resource is a virtual manipulative that allows the user to change the angle of incidence of light and select from a variety of materials, each of which has a different index of refraction, to demonstrate how light may be refracted.

Bending Light Simulation This tool is useful for introducing students to the concept that light or electromagnetic waves pass through different substances at different speeds and in different directions.
