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.
A car won't run without fuel. And just like a car, the human body can't be expected to work without the food and nutrients it uses as fuel. Good nutrition and exercise are always important! Students learn about the food pyramid, as well as the types and amounts of foods needed by the body each day to stay healthy. Children find out how calories burn and how exercise keeps the body in shape! Students also take a look at how an unbalanced diet, overeating and lack of exercise can wear the body down and affect well-being. A hands-on activity is included. Part of the multivolume Human Body for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title is based on the concepts outlined in the National Science Education Standards for Life Science: characteristics of organisms, life cycles of organisms and organisms and environments.

Your brain controls everything you do -- from breathing, to feeling, to learning and playing. All About the Brain introduces kids to the human nervous system, which is comprised of the brain, the spinal cord and a vast network of nerves. Discover the basic units of the nervous system, and explore the functions of the three main parts of the brain: the cerebrum, the cerebellum and the brain stem. Colorful graphics and exciting, real-life examples help young students understand how messages constantly travel back and forth between the brain and all of the other parts of the body. A fun demonstration shows how the brain is protected not only by the skull, but by a layer of fluid as well. Reflexes are discussed, and an easy-to-replicate experiment is included in which kids actually measure their own reaction time.

Most kids understand that many plants sprout from seeds, grow flowers and make new seeds, and then the whole process starts all over again. What they may not realize is that this is an example of a life cycle, and it applies to people, too! In All About the Human Life Cycle, students will discover that there are stages that all of us pass through as we grow: birth, infancy, childhood, adolescence and adulthood. Each of these is described by using real-life examples against the backdrop of a family picnic. The concept of a cycle is stressed, making it clear that the cycle of life repeats again and again with each new baby that is born. A fun activity is included in which kids witness the stages of a life cycle up close through observing the metamorphosis of a caterpillar into a butterfly.

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.
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. This program is 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. 23 minutes. Grades K to 4.
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.

Winter, spring, summer and fall. We know what happens in our own backyards at these times during the year, but it isn't the same everywhere in the world! When it's warm and sunny where you are, it might be very different in other places of the world. Why do the seasons change? And what causes different regions in the world to have different climates? These and other questions are answered in All About Climate & Seasons, where young students will learn about these yearly changes through engaging examples and explanations. A hands-on investigation shows the effects of direct sunlight on areas of the world, while Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, demonstrates the concept behind the device known as an orrery.
