Explains how electricity works, introducing the concepts of positive and negative charges, circuits, conductors, and insulators using real-life examples and colorful graphics, and includes a hands-on activity.
A lively explanation of everyday weather forms. Learn about various types of clouds and how the wind affects them. A meteorologist demonstrates how wind speed is measured with an anemometer. Also, build your own weather vane.
See how scientific deduction and high-tech equipment allows meteorologists to predict the weather. Up-close look at the equipment, and concepts such as the water cycle and air pressure. Hands-on demonstration to set up a mini-weather station.
An explanation of everyday weather forms and the forces that cause them. Learn about the sky, storm clouds and water pressure. A meteorologist demonstrates how measurement and observation of rainfall helps determine the forecast. Hands-on demonstrations showing that air has weight.
Learn how the concepts of velocity, acceleration and momentumn are factors in unbalanced forces, which create motion, and balanced forces, which keep things still. Hands-on activity.
Introduces the concepts of forces, work, and how machines are used to make work easier, with descriptions of six simple machines, including the lever, wheel and axle, pulley, inclined plane, screw, and wedge.
