Sound, like light, travels in waves. Young students learn about the amazing journey of sound -- from the source that creates the sound to the mechanics of the ear that enable it to be heard. Children discover why sound needs a 'medium' to travel, why there is no sound in space and how certain animals are able to 'see' by using sound! A fun, hands-on activity and clearly illustrated diagrams help students learn these basic concepts. One of 11 volumes in the Physical Science for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title correlates to the National Science Education Standards for Physical Science -- properties of objects and materials, position and motion of objects and light, heat, electricity and magnetism. A Teacher's Guide is included and available online. Grades K-4. 23 minutes.
Walking on a balance beam or riding a bike both require motion and balance. This program will reveal how unbalanced forces create motion, while balanced forces keep things still. Students also learn how concepts like velocity, acceleration and momentum fit into this puzzle. A unique hands-on activity combined with vivid imagery and graphics will clearly illustrate these concepts to students.

When we try to move ourselves or other objects, a force is being created -- a push or a pull. Students learn about how forces are involved in everything we do and about the natural force that affects us every minute of every day. How does it help or hinder us in our everyday lives? With clear demonstrations and a fun, hands-on activity, these concepts are more easily understood.

Up, up and away! A hot air balloon, an airplane and even the space shuttle all defy the force of gravity, but they all do it in different ways. Children learn about the basic concepts that make flight possible. With clear demonstrations and a hands-on project, students will be able to understand more easily the basic concepts behind various types of flight.
