Things I have considered:
The Rainbow: still a possibility, but expensive, therefore, low on the list
Beefed-up Elementary Apologia: daughter doesn't want to do something easier than General Science, but this is my favorite option *ETA: My daughter didn't know there was an Astronomy book. She is excited now to do this possibility. YEAH! THE SEARCH FOR SCIENCE IS OVER!
Christian Light Publishing LightUnits: still a good possibility, but not very CM-ish I've heard, affordable
Light of Faith: still reviewing
A.C.E. Paces: still reviewing, affordable, again, not CM
Spectrum Science: cheap possibility, will preview some this weekend
Living Books Curriculum: just beginning to look....
Reading biographies, experiment books and other living science books we have on hand, keeping a notebook (as with Apologia), writing essays and performing experiments as desired.
Anyone have more suggestions to look in to? Thoughts or opinions on any of the choices I have listed? Any help would be greatly appreciated!
