Science Book Shenanigans

Yuki and I didn't get to finish Sugar Cane today, unfortunately. She had some science homework that took up all of our time. Strangely, the science topic was the same one that Miki just learned a couple of weeks ago. Yuki is in the 8th grade and uses a standard 8th grade science textbook. Miki uses a standard 7th grade text book. The portion that Yuki is studying is, word for word, the same in Miki's textbook. They don't go to the same middle school, but they're in the same school system. I'm still not sure what the explanation might be. But in any case, it was helpful because I had experience explaining it very simply to Miki, so I was on the ball with simple English and easy examples to teach cells and the characteristics of life to Yuki.
