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.

Ninety percent of Earth is made of minerals, natural materials that form the building blocks of the solid structures on our planet. In Minerals, students will examine the makeup of a mineral as they review such properties as hardness, luster, cleavage, streak, color and density. Learn where minerals can be found, and see the many different uses of these natural wonders, which include powder, tools, jewelry and medicine. A visit to an old silver mine shows how miners removed valuable silver ore over 100 years ago, while a fun, hands-on investigation demonstrates the crystalline structure of minerals.

Borosil brand pipettes are manufactured from specially selected heavy-wall machine-drawn borosilicate accurate bore glass tubing. They have precision formed jets and bevel ground ends to resist chipping. The graduation marks are in durable white enamel or amber stain, both are resistant to normal laboratory agents and repeated washing. All the pipettes are individually measured and then marked. Accuracy is ensured between any two readings, because of uniformity of bore. The pipettes can be autoclaved and if necessary can be flamed for sterilization.
