This was a fabulous science curriculum! We loved it. It was interesting, and the student pages were well written. The labs are manageable, informative, and easy to follow, and I loved the teacher’s guide. I wish I had found Sonlight Science earlier. You will need to purchase the student pages and the science kit from Sonlight. Otherwise this is complete. Condition depends on items. I tried to show damage in pictures. The atlas has classroom use and is in fair condition. The instructor notes have pencil underlines in them and do not include the student pages. (Student pages can be purchased from Sonlight.) All other books are in good to excellent condition.
