An introduction to the sciences that wakens the imagination, conveys useful knowledge, and opens the doors towards wisdom. Its special aim is to stimulate observation and to excite a living and lasting interest in the world that lies about us. The sciences of astronomy, physics, chemistry, meteorology, and physiography are treated as fully and as deeply as the conditions permit; and the lessons that they teach are enforced by examples taken from familiar and important things. Dozens of illustrations depict the features described in the text. Suitable for ages 11 and up.
I think this would be fine for 8& up, not 11&up. I read it to my high schooler and he already knew most everything in it, but I liked it as a review of all the disciplines of science before we delve more deeply into each one again.
I read this to my boys this year as an introduction to some of the different types of sciences. It was a perfect fit for their ages—mainly for the 11 year old, but the 7 year old always tags along. The dialogue makes it easy to read and enjoyable. If the book shared an idea for an experiment we would do it, and I would have them put an entry in their science notebooks. It fit nicely as a Year 5 read.
