The class will present the science of sound and how sound waves are produced. We will study how sound waves are produced by mechanical vibrations, explore how there are different ways to produce vibrations, and learn how sound waves are examples of compressional waves. The class will cover why sound waves can not travel in space and will also generally compare sound waves to light waves. Students will observe or perform demonstrations and tricks that show the surprising and amplifying properties of sound.

Teacher expertise and credentials
Doctoral Degree in Science from Rutgers University
For over 25 years I have taught science in some context to elementary, middle, secondary, and college students. I have taught science education courses in a teacher education program and have even taught pre-K and Kindergarten science. I have always strived to make my class interesting and fun for students and I have applied that approach to all of my online science classes. I have taught online classes for middle school students (chemistry, microbiology, and physics) as well as classes for elementary students. My classes include interesting demonstrations for students, occasional humor, as well as content that aligns to NGSS standards. I am also the author of the Dr. Dave’s Science Teaching Manuals, a series of instructional manuals for elementary, middle-school and secondary science teachers. Reviews
