Spectrum Science, Grade 6: Volume 58

The book has 152 pages, divided into topics: science as inquiry, physical science, life science, earth and space science, technology, science in personal and social perspectives, history and nature of science.In total, there are 70 lessons (topics), each of a single page with a glossary. Facing page are exercises. We haven't started using it, but it looks good (that is why I rated only 4 stars, because I can only be sure after using it with my child).It has color photographs or drawings, pages can be taken off and in the end, there is the Answer Key.It is not a complete science book (by it's small size), but it is enough for my purposes (I use it only a support for school, as my daughter goes to grammar school in Germany and they study very different things there). We can't take long textbooks then, for lack of time.
