We used Biology 101, and it was a nice relaxed style learning. I added in labs, etc. so it counted as a lab science. Even my then 10 yo learned from it.

*One Small Square: Backyard &/or Woods – this is good for an older student if you have them do the actual square foot and observe it. The others, and there are several, are also very good used in conjunction with a video or other book.
I can’t find my books on mushrooms and there are more concerning microscopy/single-celled organisms. I think one is Life in a Drop of Water, and maybe another is about Leeuwenhoek. My girls found them a little on the dry side, but they are full of information. I think there are several in the same series which are possibly for younger children, perhaps upper elementary to junior high, but they are, again, chock full of information. And, for a student who is not enthusiastic over science, they may interest him/her. The series is Great Minds of Science, I believe.
