Subjects: Physical Science

Two students in search of ideas for a science project find help in a store like one they’ve never seen. Miss Dallerwag, the store owner, helps explain concepts like atoms and molecules. She also describes what mass, volume, and density are and how they are different, and the states of matter and how they change. With the insights and understanding the students gain from this experience, the science project turns out to be a big success. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections.

Isaac Newton himself shows students how gravity, friction, and inertia are related to mass, force, and momentum. Exciting graphics and re-creations allow students to see how Newton’s laws of motion relate to real life. Experiments with roller blades, baseballs, and other common objects encourage students to make science exploration recreational. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections..

Amanda’s friend Kyle is having trouble understanding matter, but she knows just the thing to do. She takes him to “A Matter of Fact,” an interesting store full of scientific things-and a peculiar storeowner to help them! Kyle learns all about the physical and chemical properties of matter, such as conductivity, magnetism, and combustibility. He finds out what mixtures and solutions are. Last, he learns about the physical and chemical changes of matter like rusting, tarnishing, and burning. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections.

Learn about electricity when Ben Franklin leaps out of the pages of a student’s science textbook to help him with his homework. Using the latest computer graphics and experiments, Ben explains concepts such as lightning, static electricity, and simple, series, and parallel circuits. Discover the relationship between electricity and magnetism and learn that a variety of energy sources can produce electricity. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections.

When “Hardware Hal” holds a “Simple and Compound Machines Sale” he demonstrates to his assistants the six simple machines: the lever, wedge, inclined plane, pulley, wheel & axle, and screw. Shows how these machines make work easier by changing force, direction, or distance. Machines in action and computer graphics illustrate the principles of work, effort, force, distance, power, friction, and much more. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections.

Energy is all around you. Learn about the many different types of energy and how energy can change form. Vivid examples illustrate how potential energy and kinetic energy are defined, and how one form of energy can change into another. Discover that energy never goes away and that it can only be transferred from one form into another. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections: (1) Introduction (2) What is energy? (3) Work (4) Forms of energy (5) Potential and kinetic energy (6) Review.

Students learn about gravity. First stop – Earth – to discover how gravity affects people and things on this planet. Next stop – outer space – to learn how gravity affects other planets. This learning journey demonstrates the effects of mass on gravity and the difference between mass and weight in a way that is easy to understand and fun to watch. DVD features include on-screen teacher’s guide and vocabulary plus chapter selections.
