book number 1, MAGNETS

Magnetism is an invisible force. Some types of metals have this magnetic force. A material that has a magnetic force is called a magnet. (p.8)

     I learned about magnets from this book. Magnet hide around us. For example, refrigerator, doorbells, and compasses. So, we can see them around us. The biggest magnet on our planet is the planet, earth. Our earth's core is made up of solid iron and hot liquid iron. I learned that in high school. Some nights, far north or far south, we can see aurora borealis or aurora australis. I heard that these are very beautiful. I want to see it sometimes!
