Query: Really great for science-minded kids

My 6-year old son is hooked on these stories, all of them! He likes them better than Magic Tree House. The science learning comes in fun and funny ways and is not so "obvious." You learn so much (adults included!) by seeing common things at the microscopic level.The one problem I've had is that they mostly need to be read in order. I didn't realize that when we began in the middle with the book that looked most appealing to my child.
