Standards Addressed
Waves

4. Waves have characteristic properties that do not depend on the type of wave. As a basis for understanding this concept:
a. Students know waves carry energy from one place to another.
b. Students know how to identify transverse and longitudinal waves in mechanical media, such as springs and ropes, and on the earth (seismic waves).
c. Students know how to solve problems involving wavelength, frequency, and wave speed.
d. Students know sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.

Instructional Objectives

Given several examples of Doppler waves students will be able to indicate which is moving at the highest velocity and in what direction they are traveling.

Given a model of a wave students will be able to label amplitude, trough, wavelength and normal rest position.

Given three mediums and three speeds, students be asked to estimate the speed of sound through the different mediums by matching them.

The student will identify and label longitudinal and transverse waves.

The student could be asked to solve the following in which speed, distance and time are the variables.

Student Activities

Introductory Activity
The teacher appears wearing his or her Police helmet and radar gun. Pretending to have pulled the class over and showing them the speed they were traveling. Then saying wait a minute how does he do that? He does it by smashing waves against your car and measuring what your car did to the wave.

PRETEST (web page) (word doc)

1. Introduce the components of compressional and transverse.
2. Students will be given speed problems involving different mediums that waves travel through.
3. Students will review wave PowerPoint (WAVE POWERPOINT)
4. Students will visit physics (GO THROUGH LESSON 1 & 2)webpage, read and take online quiz. (SOUND WEB PAGE)
5. Students will go to practice quiz page and take online quiz. (ONLINE PRACTICE QUIZ) writing down answers in a note book or separate sheet of paper.

6. Students will take pre/post test from copy of word document or go to funbrain.com take the test online. Teacher needs to go to funbrain prior to the day of test and sign up for access. Once signed up teacher and students will have access to sound test online. Funbrain.com will send you students results from test via email or you can see it online.(online test)

Culminating Activity
Students will perform sound lab.
