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.

Obviously, we need to know where things are in order to function. And, many times we need to be able to “see” something even when it is dark outside or something is far away and obstructed, by the ocean or clouds, for example. Engineers have learned from nature how to use sound and radio waves to locate objects. This technology is called SONAR (SOund wave Navigation And Ranging) and RADAR (RADio wave navigation And Ranging).Explain the basics of echolocation.Give an example of an echolocation application.20TeachEngineering.orgFrank BurkholderTeresa EllisBrian KayAbigail WatrousJanet Yowellhttp://gbs.glenbrook.k12.il.us/Academics/gbssci/phys/mmedia/waves/tfl.htmlhttp://www.jpl.nasa.gov/history/innovations/1983_sunken_ship.htmhttp://www.gmi.edu/~drussell/Demos.htmlhttp://www.state.gov/r/pa/ei/pix/b/nea/iraq/19132.htm http://www.hcs.harvard.edu/~hsmbb/BRAIN/vol1/echo.htmlhttp://www.thewildones.org/Animals/echolocation.htmlhttp://en.wikipedia.org/wiki/Animal_echolocationhttp://en.wikipedia.org/wiki/SonarS11416CDInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyC.
