This wildly fun activity challenges students to spawn powerful tornadoes with their typing skills. The faster a students can type the "tornado-themed" words that appear, the more powerful the tornado becomes. Students have 25 total seconds to type as many words as possible. If students can produce super-massive tornadoes , exceeding 500 mph, their tornadoes can turn into sharknadoes, pignadoes, frognadoes, and other kinds of tornadoes.

What happens when ocean currents and air masses interact? Find out in Weather Lab! Take on the role of a meteorologist by predicting spring weather and how people should dress for it in particular regions of the United States.

Weather Lab is a tool to help visualize how North America's weather is formed. This lab is designed to model the complex interactions between air masses and ocean currents, but like all models it represents probable outcomes. Each prediction you make is for possible outcomes during Spring.

Weather Lab is available as a website for desktop and laptop computers, tablets, and smartphones.
