Your post had me thinking about the book so I pulled it out. We actually have this one and I highly recommend it. The other has a lot of the same experiments (based on the table of contents) but this one has a lot more. Also, I was a long term sub when the boys lived with us once they were both in school and I have used this book for high school science class where I had kids pull experiments from it to do so it ranges from very young all the way up.
