This earth science volume makes science concepts accessible and fun, while also emphasizing some very important points. Earth itself is made of rocks and minerals. We use these natural resources in many ways. We build tall buildings with iron. We create pathways for electricity with copper. We absorb minerals' nutrients to keep our bodies healthy. We even wear precious gems and metals as decorations. These natural resources are precious and we must protect them, as your readers will learn. Color photographs, fact boxes, a hands-on activity, and 'Words to Know' are also included.
