Presents three key concepts of science: static electricity, magnetism, and generating electricity. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Investigates some of the key concepts of physics. Using a drum kit, we look at how sound works, how we make it, and how it gets around. Also, examines electricity and electromagnetism and notes the similarities between a remote control car and a mobile phone charger. Finally, takes a look at radioactivity and identifies a radioactive device that can be found in almost every family home.
Grab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge.

What is electricity and how is it made? What kinds are there? What are circuits and switches? Is electricity dangerous? Answers these questions with easy-to-duplicate experiments.
A lit up lamp is the end of an electrical circuit. How is energy produced? How is it distributed? A team traces the path of electricity from the power plant to its place of consumption. Part of Invisible Science and Technology Surrounding Series.
Features a device that indicates the direction and force of an earthquake. Overviews odometers, the compass, gimbals, intricate differential gears, double-action piston bellows, and continuous flamethrowers. Also relates how rudders, bulkheads, and fore and aft sails enable a ship to sail against the wind.
Students learn the fundamental concepts of electrical energy. Easy-to-understand animations illustrate the concepts of electric charge and electric current. Static electricity and the role it plays in creating lightning is also described. Important terminology includes protons, electrons, repel, attract, charges, charged objects, electrical discharge, electric field, and electric force.
Electricity makes life easier every day. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. Students will discover the properties of electricity and what is needed to keep the lights on. Part of the Real World Science series.
Students explore the various properties of magnets and the characteristics of magnetic force. Graphics and real-life footage explain how magnets are used in generating electricity. Electromagnets and their many uses are demonstrated as well. Other terminology includes: magnetic poles, magnetic field, electric motor, generator, solenoid, and electromagnetism.
Magnets can be found in many objects used everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. Students will gain general information about magnetism, as well as concepts about atoms and the relationship between electricity and magnets. Part of the Real World Science series.
Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
The rate of a chemical reaction is affected by a number of factors, including temperature and the concentration of reactants at the beginning of the reaction. While the chemical equation may show reactants turning into products as a straightforward process, it is actually involved and precise. How exactly do reactants turn into products? Sometimes, the answer is as simple as two atoms bumping into each other and forming a bond. Most of the time, however, the process is much more complex. Controlling the rate of reactions has implications for a variety of applications, including drug design and corrosion prevention. Part of the series Chemistry: Challenges And Solutions.
Part of the "A 3-D Demonstration" series. Explores how electric energy became an essential tool with the advent of electricity storage, allowing the flow of current to do useful work. Defines and examines conductors, insulators, voltage, and current, using a water flow model to help ensure understanding. Explains the difference between electron flow and current flow models. Also develops the nature of direct and alternating current (both one- and two-phase). Specific modules include Tapping a Source, Conductors and Insulators, Direction of Flow, Potential Difference, Measuring Voltage, Measuring Current, Alternating Current, and AC Voltage. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Currents in the Pacific Ocean have brought derelict fishing nets and gear to the waters around the Hawaiian islands. These nets are a safety hazard to ships and cause extensive damage to the ecosystem by snagging on coral reefs, entangling wildlife, and polluting shorelines. Instead of adding these nets to already congested landfills, Hawaii’s multi-partner marine debris group came up with a unique program to downcycle this marine debris into usable electricity.
How can you tell the difference between a fruit and a vegetable? Students learn their similarities and differences. What is the relationship between a magnet and compass? Scientists explain how a compass works. Part of the House of Science Series.
Adabot meets James Prescott Joule and learns all about the joule, a unit which measures work. Part of the "Circuit Playground" series.
Adabot wants to know how a light-emitting diode (LED) works. Billie, the blue LED, helps answer the questions. Part of the "Circuit Playground" series.
Ladyada and Adabot explain the electrochemical reactions that take place in batteries. After discussing how batteries work, they build a battery out of lemons. Part of the "Circuit Playground" series.
Adabot learns about electromagnetic energy with the help of a new friend, Mr. Heinrich Hertz. Part of the "Circuit Playground" series.
Hans, the integrated circiuit (IC), stops by the lab and explains the role of ICs in an electrical circuit. Part of the "Circuit Playground" series.
