My son doesn't like science, and I was looking for something that would appeal to him. Science in machines, inventions, aircraft, I thought would be interesting. I viewed the book on CBD, and the pics were colorful, which was a plus. I purchased the book, and my son who hates science actually had to admit it was interesting.
Another plus are the lessons plans... very easy to follow. The daily questions are laid out for you. CD's also accompany the book set, which have worksheets to be printed for extra practice on particular subjects. I am very impressed with this curriculum.. it's been well thought and planned out... leaving no "guess work" , and requires little superrvision for older students. My son is in 8th grade and does his work self directed each day. ( Although, I do print out the worksheets and instruct him when he needs to work on each one, and I use a notebook for the questions at the end of each lesson.)
Each book has a a teacher's guide as well. These guides explain how to perform experiments from the CD's, and gives instructions for the printable worksheets. Like I said.. this is a well thought out science program, yet soo easy to follow. I asked my husband, "Where was this science program when I was homeschooling my girls 10 yrs ago?" A side note.. this is a mult-age program... designed to fit various ages.. Taking it Further for older students... cannot recommend enough!
