Unit 7 Ps4-1

Words: 429
Pages: 2

Targets
The students will be able to understand what transverse and longitudinal waves are, and will understand how wave speed is affected by the tension on a medium. Identify the parts of a wave and draw their own diagrams of waves. Analyze the electromagnetic spectrum to identify waves with higher or lower energy. Analyze the electromagnetic spectrum to identify waves with longer or shorter wavelengths.
Standards:
HS-PS4-1: Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
RST.11-12.7: Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video, multimedia) in order to address a question or solve a problem. (HS-PS4-1),(HS-PS4-4)

Sequence of events

The goals:
To understand what transverse and longitudinal waves are.
To understand how wave speed is affected by the tension on a medium.
To identify the parts of a wave.
To analyze the electromagnetic spectrum to identify waves with higher or lower energy.
To analyze the electromagnetic spectrum to identify waves with longer or shorter wavelengths.

Bell work:
Grab the following:
A computer per 2 students (log into it)
Finish up their slinky lab.

Explore:
[15 – 20 minutes depending on progress] The students will work in pairs to finish the slinky lab activity to understand what longitudinal and transverse waves are. They will encounter bold and italicized vocabulary words that they will need to research in order to be able to proceed with the investigation. They will either define or make a picture that defines each of the vocabulary words.

[4 minutes] The students will come up with examples of longitudinal waves and transverse wave (i.e., radio waves, sound waves
