Audience: Students; Grades: 4-5; Subject Areas: Science. (2006) We live in an ocean of air. It's all around us, everyplace, all the time ... so most of the time we don't even think about it. We only notice air when it moves ? when it becomes a wind. Wind can be part of a storm that can make for messy weather. In certain parts of the country people have to watch out for one of the most dangerous forms that wind can take, tornadoes!
