My son received this when he was almost 4, and understood the concepts of solid, liquid, and gases by 4.5yo! This describes the concepts in such a way that youngsters can easily understand, but won't bore older children. I would highly recommend this book, along with other books in the "Let's-Read-And-Find-Out Science" series.
This is a delightful book with good illustrations. It can be helpful in teaching children in grades 1-3 about physical properties in language they can understand. I recommend it highly. The only disadvantage is that now the physicists are telling us that there are 4 states of matter - the 4th being plasma, so the book is leaving out the newest category. However, I'm sure in the next edition the author and illustrator will find an engaging way to include the 4th state - the biggest example of which is our sun. So - if you're looking for books to teach early grade students about science, look at this author's work (Kathleen Weidner Zoehfeld). She has many engaging books to help us educate our children, and have fun while we're doing it.
I have a 6-yr old boy and a 7-yr old girl. It's very rare to find anything that they agree on but with What Is the World Made Of? I was able to find a book that both of them would enjoy and learn from at the same time. The easy-to-follow language made it easy for them both to follow along. The fun pictures and odd bits of humor kept them interested and wanting to know more. A fantastic find & one I hope to be able to use for quite some time.
After reading this to my daughter last night, we engaged in a 30 minute long game of "Solid, Liquid, or Gas?" The book does a great job of explaining the states of matter. For the "Try It Yourself" sections it, of course, uses water for a test subject, going through freezing, evaporation, and condensation. I had to promise that we would do the experiments today.
Once again, I would recommend this book to anyone wanting to teach their young children about basic science.
Great introduction to these concepts for young kids. I had already explored the different states of water with my 6 year old, but it was nice to be able to reinforce that process. My son often said, "I already know that" for the basic concepts, but I felt that the specific examples of the different states of all types of matter were very helpful in getting him to understand that there's an order to the way things work. By the end of it, he really enjoyed the book. Don't miss the three exercises at the end of the book - they are fun activities that make learning science hands-on.
