When it's just not possible to take students out to explore the natural world, bring the natural world to the classroom. Clearly organized and easy to use, this helpful guide contains more than 50 science lessons in six units: Greening the School, Insects, Plants, Rocks and Soils, Water, and In the Sky. All lessons include objectives, materials lists, procedures, reproducible data sheets, ideas for adapting to different grade levels, discussion questions, and next steps. Almost all the needed materials are inexpensive or even free (such as leaves and rocks), and if you do get the chance to venture outside, the lessons will work there, too. By using Steve Rich's follow up to his popular book Outdoor Science: A Practical Guide, you can introduce students to everything from bug zoos to the Sun and stars without ever needing to pull on a jacket.
