Dr. Nebel, I recently started homeschooling my 4-year-old. As a physicist, a solid science background is my top priority for my child’s education. I can’t thank you enough for writing these books!! While I know science, I am NOT an expert at teaching. You have helped me tremendously. The Baloney detection kit is my favorite part so far, and I appreciate you are keeping it up to date. Warm Regards!
