Objective(s)

Students will:

• be able to identify the characteristics of sound waves
• know the differences among speeds of sounds
• be able to graphically illustrate various concepts dealing with sound waves (Doppler effect, reflection, interference, longitudinal vs. transversal waves)
• use the velocity formula to find velocity, wavelength, or frequency of a wave given two of the three variables.

Time Required

Two 45 minute class periods

Pre-Requisite Skills

Students should have finished lesson one and two about wave basics.

The teacher should be able to project the Lesson 3 Presentation so the entire class can see it.  The presentation computer should have Internet access.

Handout needed for every student is Lesson 3 - Sound Waves. The presentation for the teacher to show is Lesson 3 Presentation.

Show Lesson 3 Presentation to the students while adding your own knowledge and science skills to the discussion.  Take the time to experiment with different values in the online simulations.  After the presentation, distribute Lesson 3 - Sound Waves and have each student demonstrate their knowledge of the material by answering the questions and drawing their own pictures to illustrate the concepts.

Consult your students' IEPs for modifications.

More math problems involving the velocity = wavelength * frequency and distance = velocity * time problems could be created for further math practice.

Feel free to edit this lesson in any way you see fit.  Just be sure to credit TIME as a source.

Check the worksheet to see if the students can graphically describe the concepts instead of just reciting them.
