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.
Have you ever wondered how a weather forecaster knows what the weather will be like? In All About Meteorology, young students will see how meteorologists can predict the weather for the upcoming week and even a few months down the road through scientific deduction and high-tech equipment. Students will visit with Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, to get an up-close look at the equipment that meteorologists use to forecast the weather and explore such concepts as the water cycle and air pressure. Through a fun, hands-on demonstration, see how students can set up their own mini-weather station to monitor conditions in their own areas. Part of the multivolume Weather for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
Natural resources include sunshine, fresh air, plants, animals, minerals and fossil fuels like coal, oil and natural gas. These things are resources because they are needed by living things. They are "natural" resources because they are all products of nature. In All About Natural Resources, children will learn about these resources and more, discovering along the way what makes some natural resources renewable and others nonrenewable. See how wind turbines provide an alternative to fossil fuels as a means of providing energy, while a fun, hands-on demonstration shows children how they can build their own simple water treatment system. Part of the Earth Science for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
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. A Teacher's Guide is included and available online. Grades K-4. 23 minutes.
Minerals are an important part of everything around us -- from the pencils we write with to the airplanes in the sky. Even the earth beneath our feet is packed solid with these essential building blocks. In All About Rocks and Minerals, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic. A visit to a lapidary shop examines some beautiful gemstones, while a fun, hands-on investigation demonstrates how solid crystals can be made from a liquid. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
Soil is the loose top layer of the Earth's surface, but what is it made of? How does it form? And why is it so important? In All About Soil, children will learn what components are needed to make the best soils for growing plants while discovering the important role that the forces of erosion play in the creation of this valuable resource. A visit to a grade school showcases a unique program that uses lunch leftovers and hungry earthworms to improve the soil in the school's garden, while an informative demonstration illustrates how sand is created from the continual erosion of rocks. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
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. 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 & environments. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
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.

The explosively dangerous eruptions of volcanoes are always a sight to behold. As visually dazzling as they can be, volcanoes also play a very important role in the creation of land formations around the world. In All About Volcanoes, children will learn the ins and outs of these lava-spewing mountains, examining their anatomy while learning about three major types: shield, cinder cone and composite volcanoes. A visit to Mammoth Mountain in California focuses on the signs that this dormant volcano may be coming to life, while an informative, hands-on activity demonstrates how a volcano erupts by building a useful model.

Set of powerful alnico magnets with keepers. Set consists of 2 bar magnets 80mm x 15mm x 10mm; a small horseshoe magnet 25mm tall x 8mm wide; and a large horseshoe magnet 35mm tall 15mm wide.
Aluminum Metal (20 gauge sheet) - 12" x 12" x .032"
500 grams of Aluminum Metal Shot.
Aluminum metal shot is often used in classrooms for chemistry experiments and demonstrations, such as studying chemical reactions, investigating metal properties, and exploring concepts like density and reactivity. It is commonly used in reaction experiments with acids (like hydrochloric acid) to produce hydrogen gas, allowing students to observe the properties of metal reactivity and gas evolution. Additionally, aluminum shot can be used in physics experiments to study thermal conductivity and heat transfer due to its high thermal conductivity and low density.
