A few things teachers are saying…
“They loved the whole thing. It was very well written. I read aloud to elementary students all day every day and every class from k-6 enjoyed it, learned from it and got excited to be an energy detective at home. The flap at the end was a genius addition. Bravo on a very written and illustrated book on a very important topic!” 
“These are terrific books and I love that I can give them to my students to take home!”
“I just gave out The Mystery of the Snow books to all my students and it was a huge hit!”
“Used these last year with my 5th graders and it was great. Can't wait for the solar books!”
Free Books For Every Elementary Student
In 2024, we invited educators to our program by sending our first book, The Mystery of the Snow. In 2025, we released our second book, The Secrets of the Sun! Both are written by award-winning author Madelyn Rosenberg and illustrated by Paul Meisel. Our series offers an interactive way for educators to introduce standards-based energy concepts, while also teaching students about climate action. Order now!

It’s not just for science! Incorporate hands-on climate and energy learning into your social studies, math, and ELA instruction with our free, hands-on lesson plans that support the book. The curriculum aligns with national standards or higher and was designed by classroom teachers to be simple and flexible to meet your schedule and instructional needs. It has been a hit!
