Of course it's appropriate. "grimace physics class" is a set of physics auxiliary books that accurately relate to middle school textbooks. The language is humorous. It uses various stories to talk about the key points and difficulties in physics, and there are many interesting illustrations, which are especially suitable for children who have just learned physics. When you meet the knowledge points in the textbook, you will show them with examples, which are very vivid and attract children. I bought this book for my child when she was just learning physics. She is doing well in physics now. If I had this book when I was at school, I wouldn't have failed the physics exam. Oh, I'm sad. All right, forget it. I went to help my daughter with her homework.
