Earth is filled with a variety of land formations -- from mountains to valleys, canyons to plains. But what's the difference between a folded and a block mountain? A mesa and a butte? A bay and a peninsula? In Land Formations, students learn the answers to these and other questions as they examine how forces such as weathering and continental drift have impacted the rise and fall of land on Earth. A fun, hands-on demonstration showcases the effects of the seafloor spreading at mid-ocean ridges and sinking in deep trenches, while a visit to the dramatic Devil's Postpile illustrates how the forces of nature can shape and define the land. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.

In The Laws of Motion: Hovercrafts, students will learn how to make and use models to investigate the principles behind the laws of motion. As they test and refine their project, students -- and viewers -- are encouraged to make predictions based on experimental evidence as they learn to calculate the effect of forces on the motion of objects. The concepts of Newtonian mechanics are investigated by using clear demonstrations and graphics, and students discover how technological advancements are built on scientific knowledge. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.
