STEM Educator Hub
Curriculum-ready materials designed by marine biologist Yechiel Kuperman to bridge the gap between humorous classroom reading and rigorous biological science.
Two questions teachers ask first
What does "NGSS-aligned" mean here?
Each lesson note maps its chapter's science — ecosystems, food webs, organism structures and behaviours, water chemistry — to the Next Generation Science Standards life-science topics for grades 2–5, so you can slot a George chapter directly into an existing unit. The stories carry the concepts; the lesson notes name the standards and add the discussion questions, vocabulary, and a hands-on activity.
What is included, and what does it cost?
Everything on this page is free: chapter-by-chapter teacher lesson notes for Books 1–3, comprehension and vocabulary quizzes, printable classroom posters, and reading reward badges. No login, no paywall, no student accounts, and no tracking — download the PDFs and teach.
