Discover Your World is a free 158 page activity book from NOAA. The book is available as to download as a complete package in one PDF or you can download it in three separate sections. The sections are titled Explore the Earth, Understand the Earth, and Protect the Earth. In total the book has 43 activities appropriate for most K-12 classrooms but the majority of the activities seem to be most appropriate for grades four through eight.
Applications for Education
The activities in Discover Your World are hands-on activities designed to help students learn about topics in meteorology and climatology. A few of the activities that I like include reading nautical charts, building a barometer, and being a weather reporter.
