The book was in a little more of a used condition than I had expected but is acceptable. Shipping was a expected.We used Lyrical #3 for homeschool last year for my 3rd & 5th graders. After just 1 section, I dropped it from my 3rd grader's curriculum. The vocabulary is too complex for elementary age children. I do think it is helpful to put these scientific lessons to music, and the illustrations were good, though. I would recommend this for junior high school age children after completing it with my 11 year old.I was not satisfied at all with my purchase. The book looks fine but it is supposed to come with a CD. The title is "LYRICAL" it is supposed to be taught with music that you follow along with. If I knew it was not a complete set I would not have purchased it.I only recognized 2 of the songs in this book, it said it was supposed to be familiar folk songs. The main thing I did not like was the reproductive section was way too graphic and descriptive for what I want to present to my children. My kids are ages 13 down to 3 years old, and I really don't want to be singing songs about sperm and male seed swimming together as a sing along. I would rather have had that section removed. I feel like I wasted my money. There were no hands-on activities or experiments. Maybe that is just as well because I don't know what they would have done on the reproductive section for that... :) ! I will not be using this as part of my curriculum.Lyrical Life Science is a great book for learning about the human body. They go into detail for each of the parts and systems, and do so with songs that help reinforce the concepts and information for help with retention. It's a great resource for upper elementary through high school education teachers.According to the ISBN, this is the teacher's manual, not the student workbook as another reviewer stated.I'm sorry I haven't used it yet so can't comment on its quality.There is a CD that goes with this workbook, but it is sold separately. You should definitely buy the CD as well! The songs are catchy, well-done, and pack in lots of substantial educational info. The workbook (sold here) has fill-in-the-blanks worksheets for the words to the song, explanations of human anatomy in a concise format, and other helpful worksheets.Here's an example of lyrics from the song on the skeletal system:You have your long bones and your short bones and theflat and irregularLigaments join them at the joints, tendons connecting them tomuscularLayers of bones include hard compact and the spongy cancelloustooAnd there's the marrow in the cavity to make blood cells for allparts of you.
