| 組合： | Read and Discover Series (Primary)_II |
| 簡介： | Answering its own title question, this book takes the mystery out of magnets and magnetism in language that younger readers can readily understand. Common Core Standards in the physical sciences were considered when determining what material should be covered. Polarity, magnetic fields, electromagnetics, the difference between soft and hard magnets, and the ways in which magnets are used in industry, medicine, and everyday life are among the topics covered. Boxed inserts define terminology and challenge readers by posing questions suggested by the narrative. Suggested experiments with magnets cap this delightful volume. |
