In this activity, young scholars will witness the creation of a funnel, observe how a funnel moves debris, and learn how a thunderstorm can create tornados.

Now known as the Tri-State Tornado, it turned March 18 into a day of gruesome destruction and bizarre survival stories. This tornado hit Missouri, Illinois and Indiana and resulted in nearly 700 deaths.

Funnel clouds have been around for a long time. Check out the story of tornadoes and find out more about an outbreak of tornadoes in April of 1974.

Why do the majority of the world's twisters occur in the United States? Find out the role that geography and climate play in spawning tornadoes.

Only about one thunderstorm in a thousand produces tornadoes. Learn how tornadoes form.

Students explore factors that influence why certain areas in the United States have more tornadoes than others and observe a model to visualize what is happening during a tornado.

Meteorologist James Spann sheds light on the lifespan of tornadoes as they go from supercell thunderstorms to terrible twisters before eventually dissolving back into thin air. [4:11]

Control a tornado's intensity by manipulating its width and rotation speed.

A dark funnel of cloud extends below a storm. If it reaches the ground, it's a tornado.

Students will learn about tornadoes, the damage they cause, and how to rate tornadoes. Specifically, students will investigate the Fujita Damage Scale of tornado intensity, and use it to complete a mock engineering analysis of damage...

Students learn about tornadoes - their basic characteristics, damage and occurrences. Students are introduced to the ways that engineers consider strong winds, specifically tornadoes, in their design of structures. Also, students learn...

This activity will introduce you to the Fujita scale for rating tornado strength. You will then put your knowledge to use by observing photographs of tornado damage and assigning them a rating.
