I plan to use two Usborne Books with Classical Conversations Science weeks 1-12. I’ll probably add other books as we go each week, but these appear to work for the entire first 12 weeks.
See Inside Your Body and Usborne Human Body Reference Book. (The Human Body Reference does have a little reproductive information. Please make sure you find it appropriate for your child.)
You can buy these from an Usborne representative or you may be able to find used copies on Amazon or Ebay. (I purchased these from a friend’s party.)
Do you know of any other great books for cycle 3 science for week 1-12?
