You teach. You’re busy. We’re here to help! Use this ebook, together with Science Connected Magazine, to supplement your curriculum for students in US grades 1-6. These lessons are research-based, written by scientists, and apply current best practices. You are welcome to download the PDF for free, but please make a small donation. For the price of a Venti Frappuccino, you can help us continue to produce free and affordable science education resources. Thank you!
