I love homeschool curricula. I could just use a little of everything! For Science, I found Apologia to be great for my oldest two boys for their elem. stage. The 'Exploring Creation with Zoology - Flying Creatures, Swimming Creatures and Land Creatures'. But when we got to the middle school stage, they started to lose interest in the textbook style 'Exploring Creation with General & Physical Science'. But now, we are going back to Apologia 'Biology'.... I think for this fall.
Unlike my little one (who is now 8 yrs. old) is doing a little of everything. We use Apologia, aBeka, a stack of misc. Science Experiment books,.... you name it. I guess I will never find the 'perfect' science curricula because each of my boys are different. Their styles, attention span, interests, etc. I love that about them. It gives me a variety as well since I don't really 'crave' science like my boys.
Share what you use for Science and why. Looking forward to reading what everyone else uses. Who knows, maybe we'll try something new.....again:)
