Weather is a topic in science that is applicable to our lives on an everyday basis. The weather often determines what we wear, where we go, and what we do. This month’s column focuses on clouds and the part they play in determining our weather. In the K–3 lesson, students learn about different cloud types and sculpt each type out of shaving cream. In the lesson for grades 4–6, students learn about Luke Howard—the man responsible for naming clouds—and then investigate clouds by collecting real data for NASA’s S’COOL project.
