抄録

When junior high school students study their course of "Science", it is very important for each of them to personally contact and experience with each of natural behaviers. There are, however, many behaviers that couldn t be experienced by a student because they are micro or, on the country, super macro. In such cases, it is possible and is important for him to get a quasi-experience using such an audio-visual aid as a computer or a VTR.<BR>The sound is a kind of wave, but it is difficult to see directly the moving of air whitch is the medium of the wave. The newly developed method for visualizing the sound is to apply Laser light sheet to smoke line generated in a very low speed wind tunnel. Through this method, the transmission behavier of sound became clear vizualized.
