Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

Four mechanical wave graphs are introduced and used to understand and demonstrate transverse waves, longitudinal waves, wavelength, and period.

An introduction to mechanical waves which are defined and demonstrated. The fact that the medium is not displaced is demonstrated. Both transverse waves and longitudinal waves are also defined and demonstrated.

This video is a lesson about sound and how it works. It covers topics such as the definition of sound, how sound is produced through vibrations, the different types of waves (transverse and longitudinal), the speed of sound in different...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...
