I bought one of the Apologia textbooks when I first started homeschooling, my DD made it a short distance to where they discussed the dinosaurs on Noah's ark and closed the book for good.
My DD was 6th grade last year and we did a combination of PLATO middle school sciences and Glencoe texts with independent labs. Then we moved on to high school texts and a few intro college texts. That is the continued plan for next year. We have also used some of the MIT Open Courseware for high school. My key to keeping it correct is lots of living books from lots of sources so there are differing presentations.
