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. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Natural resources are created by Earth's processes and used as a source of energy for all life on Earth. While some are created over the course of millions of years, others are continually generated each and every day. In Natural Resources, students will examine both renewable and nonrenewable resources, touching on their sources and many uses. Discover the best methods of conserving nonrenewable resources, including how they are recycled and cleaned. A fun, hands-on investigation illustrates how students can observe the many different kinds of particles that can be found in the air, while a geothermal plant provides the setting for a look at how people can turn volcanic heat into electricity. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
From the highest mountains to the deepest chasms, Earth's terrain is comprised of varying levels and unique features. In Topography, students will learn how the features of Earth's surface are arranged while exploring the art and science of re-creating these terrains on maps. See how forces like earthquakes, volcanoes, water and wind have changed Earth's surface over countless centuries, and learn why studying these changes is important to learning about our planet's past and future. See how cartographers map the floor of the oceans, while an informative demonstration shows students how they can make a simple topographic map of their own. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Water is vital to all life on Earth and covers nearly three-fourths of our planet's surface. Where does it come from? Will we use it up eventually? In The Water Cycle, students learn that Earth has the same water supply today as it did millions of years ago. Examine the amazing process by which water is continually recycled and transported from place to place through evaporation, condensation and precipitation. Also find out how energy from the sun drives the water cycle and how the atmosphere prevents water from slipping away from Earth. A fun, hands-on investigation demonstrates how an artesian well works, while a visit to a desalination plant showcases how salt water is purified. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
The rocks and soil that make up Earth's surface are constantly being affected by a variety of forces, ranging from heat and frost to water and wind. In Weathering and Erosion, students will discover the natural forces that cause weathering, erosion and deposition, and see the many effects that these processes have on Earth's surface. Students will examine natural structures around the world and see how weathering and erosion have affected them, while discovering ways in which people have become better prepared to battle these forces through conservation. In addition, a fun, hands-on experiment demonstrates how running water erodes different types of soil. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Set against the backdrop of a soccer team in action, Cells takes a close-up look at the smallest living unit in the human body. Kids will discover that, while most cells are very similar in structure and equipment, each type of cell has its own special function. Colorful, detailed graphics give viewers a complete rundown of the various parts of a cell. Inside the cell, they'll see various organelles -- the individual parts that work together to keep the cell functioning. Cell specialization and the process of cellular reproduction known as mitosis are also covered. Includes a fun, hands-on activity that demonstrates the concept of a "selective membrane." One of ten volumes in the Human Body in Action DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title is based on the concepts outlined in the National Science Education Standards for Life Science: structure & function in living systems, reproduction & heredity, regulation & behavior, and diversity & adaptations of organisms. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
For thousands of years, humans dreamed of flying -- but it isn't as easy as birds make it look. Students will learn about lift, gravity, thrust and drag -- the forces that are used to get tons of steel off the ground and carry people thousands of miles before landing safely. They will also discover the role atoms and air pressure play in this amazing task as well as in other forms of flight. An interesting hands-on activity is included along with fun, real-life demonstrations to further illustrate these concepts. One of 16 volumes in the Physical Science in Action DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Physical Science -- properties and changes in properties of matter, motions and forces and transfer of energy. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
