Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Pupils explore the Dollper effect by finding the frequency and velocity of sound.  In this velocity lesson, students determine the impulse during a collision by using their data and a software program.

Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.

Students view video segments which reveal the parts of sound and what factors control sound. The viewing and post-viewing activities serve to reinforce the video segments using worksheets and hands-out experiments.

High schoolers practice manipulating algebra formulas with more than one variable. They examine the topics of velocity, wavelength and frequency. They determine the amount of red-shift in a receding star.

Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe...
