This web site lists several different places a student could go to learn more about physics. It includes more than just sound options.

http://www.smgaels.org/physics/sound_1.htm

This web sites gives some history to who helped with discoveries about sound waves and some applications of sound. It is not very detailed.

A student’s understanding and explanation of the physics of a sub woofer is given at this web site.

This site talks about the following sound concepts: vibrations, sound waves, frequency, pitch, resonance and overtones.

This is a great site and covers: pitch, amplification, timbre, how sound travels, how the ear works, and how sound is conveyed to the brain.

Students are able to explore the physics of different things from sound to skating by clicking on different letters. The whole site is created by students and is therefore easy to understand and follow.

A source where more practice can be found to give to students is in the Advanced Mathematics: A Precalculus Approach book. Beginning on page 126 there is text that students can read to deepen their understanding. At the end of the text for this section there are practice problems that can be assigned to give students further practice.

If you are working with a younger less experienced group of students I recommend the Advanced Algebra test listed in the student resources. The reading level of this book is a little lower than the book mentioned above and students can easily understand. The practice can be found on pages 418 and 419.

In the Advanced Algebra text you will find all of chapter 9 deals with trigonometric functions and I recommend this for more practice or as a reading assignment for the students depending on what you are working on at the time.

For the precalculus students I recommend looking at chapter 4, section 2 in the Advanced Functions: A Precalculus Approach book.

Again, for more practice for your students I recommend using pages 196 and 197 from the Advanced Functions: A Precalculus Approach book. I also recommend using practice 4.2 from the teachers supplement book.

I wrote to the TI-web site to obtain permission to include the program in this paper. They said they did not have a copy and that permission would have to be obtained from the author. I received the program from a colleague who is not sure where it originated. For that reason, the program is not included here. I am still trying to track down the author and when I have done so will be happy to send a copy to anyone who would like it. You may contact me at HYPERLINK mailto:AndreaSorrellsaol.com AndreaSorrellsaol.com to see if I am able to send you a copy and all I will be happy to respond.

See note number 6 for problems that you could assign as homework.
