I am new to this board . I have researched curriculums for over 6 months now and I feel HOD is the best one for my family. I am very impressed with the guides and the reviews I read .
However , I was wondering if the science part of HOD is "meaty" enough especially that our family is on the science side

I have a degree in biology &chemistry and my kids seem more interested in science than history as well .Most Christian curriculums here in the US focus a lot on history though . I am from France where the schools put more emphasis on math and science than history . I own a lot of books , living & textbooks. My problem is to implement them without a guide . We sort of unschooled science until now , reading a lot of living books and doing many experiments but as my dc are getting older , I feel they need a more structured and deeper science . I cannot do it without a schedule or a guide ! I have a toddler and an infant , they keep me so busy that I forget about science .
So for those who are more science people , do you add anything to HOD and what would be a good supplement ? Please recommend something for grades 4-8 . I have apologia astronomy and my dc read it when he was 7 . We would prefer something that has a wider Scope & Sequence , including physics , chemistry , etc Abeka seems to fit this but I was wondering if it would not add too much to our HOD schedule ? I still want my dc to do the science scheduled in HOD and not miss anything

Suggestions?
