Mother nature can be both terrifying and fascinating to watch. At times, the air and weather are calm and pleasant. At other times, hurricanes and storms leave destruction in their path. Learning about the air and the weather is always interesting, as well as important. To understand how the weather works, students have to understand how changes in air affect it. I created this free lesson Air minilesson as an introduction to my air and weather unit. You can use it to help your students understand more about how the weather works.
