I recently saw this interesting science series. What intrigues me the most is that it is written by a science-teacher-turned-homeschooler mom that I "run into" at a lot of Charlotte Mason and Classical homeschooling sites.
Makita sees as I do a lack of solid middle school science for homeschoolers that is not written from a Creationist perspective. (It's great that such excellent Creationist material is available, BTW, since you are unlikely to find anything about it at your local library.)
As a result she created Science Logic: Sciences for the Logic Stage. While I have not seen the whole package, she has a free sample download of her first one, Earth Logic, and it looks excellent. You can order it spiral bound, unbound, or as a pdf file. She plans on releasing Life Logic and Physics Logic later in the year. Nice job, Makita!
