Ypop: Using the Computer to Measure Sunspots

Power to the people who understand electricity. A simple experiment teaches pupils how to set up an electric circuit that includes a solar module and how to measure voltage and current using a multimeter. They calculate power and...

How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

The Cold War presented some communication challenges to the US military. Because the conflict was before the launch of satellites, scientists focused on the earth's natural satellite, the moon, the bounce radio signals. A video lesson...

A gentle voice and jazz music make this video easy on the senses. It provides a close-up view of a micrometer as the narrator explains how it works and how to use one to measure the diameter of a metal wire. Since a micrometer is used...

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again. Outfit yourself with a simple handheld laser pointer, a protractor, and Jell-O, and you're ready to get started.

Young scientists explore climate change by taking a look at many different disciplines. They hear from scientists who study soil, clouds, ice cores, ocean temperatures, and more. Then, they search public databases to draw their own...

Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first lesson in a series of six.

A gentle voice and jazz music make this video easy on the senses. It provides a close-up view of a Vernier Ruler as the narrator explains how it works and how to use one to measure the diameter of a pen. Since this ruler is used for...

Not all electricity is created equal. A detailed video explains how to measure the strength of electricity using a voltmeter. The 31st installment of the 35-part series uses a demonstration to explain the process of measuring current and...

Discover the secrets used by scientists to measure mechanical waves. Young physicists learn about measurable wave qualities—amplitude, wavelength, and frequency—by watching and listening to a video discussing longitudinal and transverse...
