Minerals introduces basic scientific concepts in geology. Young children discover that minerals are formed from magma, molten material deep within the Earth. Slow cooling allows molecules to line up in an orderly way, forming minerals. Minerals can form crystals, with each mineral having crystals of a specific shape. Silicates, such as quartz, are minerals made of silicon and oxygen atoms. Small amounts of different atoms create differently colored crystals, some of which are cut and polished and made into jewelry. Atoms and molecules are defined. A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
