The National Aeronautics and Space Administration (NASA) has produced a distance learning series of four 60-minute video programs with an accompanying Web site and companion teacher guide. This teacher guide accompanies the second video in the series. The story line of each program involves six ethnically diverse, inquisitive schoolchildren who meet in a treehouse. They seek the solution to a particular problem, and the NASA "Why?" Files series follows them through the steps of their investigation and final conclusion. In this program, the treehouse detectives learn that many of the neighborhoods in the city are experiencing a problem with dogs barking late at night and early in the morning. The program includes a visit by the treehouse friends to various NASA researchers, an audiologist, a veterinarian, and classroom teachers. Students learn about sound: what it is, how it is transmitted, and how people and animals hear. Students also learn about collecting and analyzing data. This teacher guide includes a program overview as well as science, mathematics, and educational technology concepts related to the National Standards. Each 15-minute program segment is described along with objectives, key vocabulary, suggestions for the most effective use of the videos and Web site in the classroom, and resources. In addition, each segment is accompanied by activities and worksheets. (PVD)
