It's important to practice what to do during a tornado, at home and at school.
It's only a drill, but an important one. For first grade Teacher Kristen Cashman practice makes perfect for these six and seven-year-olds.
Over at Highland Elementary in Waterloo, students practice for for a tornado about three or four times a year. But before they even go through it, they talk about the the importance of the drill first. And that includes talking to them about their tornado plan at home too.
