Benjamin Franklin is one of the most well-known Founding Fathers of America. He helped write both the Declaration of Independence and the U.S. Constitution, although these accomplishments are not the only reason why Benjamin Franklin is...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

The year 2017 has been an intense year for storms, especially across the USA, as this veteran storm chaser’s archive shows. Jason Weingart has been an avid storm chaser since 2009, but 2017 has been a particularly challenging year,...

What is electricity? How does it work? Where does it come from? Everyone has heard of electricity, but most people don’t understand much about it. Scientists have studied electricity for centuries, and they still have many unanswered...

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

This program explores the many important uses of electricity. The nature of electricity and the formation of electric current are highlighted. Special attention is also paid to safety and electricity. Concepts and terminology include:...

A flash of lightning, and a rumble of thunder. But what exactly are these spectacular occurrences? In 1752, Benjamin Franklin discovered that lightning was caused by powerful electrical discharges in clouds. He wasn’t the first person to...

Types of Weather for Children

Learn about different types and kinds of weather with this video. It is important for children to learn about the world around them. Learning about types of weather can help them with that. This...

Children on a playground use creativity and their imaginations to simulate the many different types of storms found on Earth. From thunderstorms to wind storms, to snow storms and rain storms, to hurricanes and tornadoes, the children...

Over a thousand tornadoes happen every year in the United States but only few dozen take lives. Most tornadoes are brief and weak but the tornadoes that are large and powerful can wipe homes off their foundations. Tornadoes only come...

Extreme heat from lightning creates a sound shockwave that spreads out to reach you as thunder. What makes the different sounds of thunder? It depends on how many branches lightning has, in which ways they are stretched out, how far each...

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

All thunderstorms create hazards of lightning. Some thunderstorms result in flash flooding, large hail, damaging wind or a tornado. See how to prepare for these threats at school, at home, or outside. Understand the difference between a...
