Organized roughly by concept/ technique - I would have appreciated a further organization by magnification. That is to say, when an image magn. 25X shares a page with one at 2700X and the next page is another object at 170X, you get some v. cool-looking pages... but you've lost a teaching opportunity. ( )

My opinion, I found this book quit disturbing because it shows you the worlds that you cannot see to the eye. It shows us photos from magnification images and different animals that live around us you cannot see. It is overall and interesting book, but I am not sure this kind of book would keep children interested in it. ( )

Ever wonder what a mosquito really looks like? This book is oozing with close ups of things we can see with the naked eye, but look totally different under a microscope. It's pretty amazing to see. It also contains the hidden worlds of the Earth and outer space. ( )
