This lesson plan will demonstrate how sound is made from vibration and moves in all directions from the source in waves.
The pitch of a sound is determined by the size (length, thickness) of the object making the sound. This is true of the voice boxes of animals. For example: women usually have shorter vocal cords than men and have higher pitched voices as a result.
Sound waves can be "seen" if they are translated into light. In the second half of this activity, you will find a description of this process.
1-Use science process and thinking skills
4-Communicate effectively using science language and reasoning
Invitation to Learn:
This lesson is part of the Sixth Grade Science Teacher Resource Book (TRB3) http://www.usoe.org/curr/science/core/6th/TRB6/. The TRB3 is designed to be your textbook in teaching science curriculum to your students. This book covers all the objectives of each standard and benchmark. If taught efficiently, a student should do well on the End-of-Level (CRT) tests. The TRB3 is designed for teachers who know very little about science, as well as for teachers who have a broad understanding of science.
