These are practical, informative and well-written books. In fact, using these books will actually save mom a bunch of time since everything needed to accomplish a comprehensive series of lessons is included—except the scissors and glue! Each title in the Great Science Adventure Series contains 24 lessons covering every imaginable point of interest for an elementary student. By fully utilizing the research section, more advanced students are appropriately challenged. The nicest feature of the curriculum is the informative little "library books" that the children put together to go along with each lesson. By the time the 24 lessons are completed, the children have a 24-book library on the topic. Very clever! Plenty of help to assess progress and plan lessons. Web pages throughout for further investigations.The World of Light & Sound includes the study of sunlight, reflection, refraction, light travel, rainbows, colors, shadows, lenses, sounds, hearing, lasers, heat, sound measurements and more. 24 lessons, paperback, 8 1/2"x11".

Favorite toy.
Seems to be of good quality. There are probably a dozen different name brands for these balls. Our puppy loves these. Our son’s 90 pound golden lab has had one for a couple years. He has his outside and it’s a very similar design. Although not the same manufacturer.
