In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

This is a comprehensive science textbook for Grade 10. You can download or read it on-line on your mobile phone, computer or iPad. Every chapter comes with video lessons and explanations which help bring the ideas and concepts to life.

In this activity, students use their own creativity (and their bodies) to make longitudinal and transverse waves. Through the use of common items, they will investigate the different between longitudinal and transverse waves.

This 13-minute video lesson provides an introduction to transverse and longitudinal waves. [Physics playlist: Lesson 141 of 164].

In this lesson, students learn about echolocation: what it is and how engineers use it to "see" things in the dark, or deep underwater. Also, they learn how animals use echolocation to catch their dinner and travel the ocean waters and skies without running into things.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in Lessons 6-10, they explore the concepts of light. The first lesson introduces the concepts of longitudinal and transverse waves. Students then move on to the concepts of wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, girls and boys learn all about echolocation what it is and how engineers use it to "see" things in the dark, or deep underwater. The last of the five sound lessons introduces acoustics, in which students learn how different materials reflect and absorb sound.

This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme of the Sound and Light unit a continuous story line throughout the lessons.

For middle school and up, an introduction to some acoustics terms and how they relate to music.

For middle school and up, a short explanation of the difference between transverse and longitudinal waves, with some suggestions for classroom presentation.

Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.
