Minerals are an important part of everything around us - from the pencils we write with to the airplanes in the sky. Even the earth beneath our feet is packed solid with these essential building blocks. In this program, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic. A visit to a lapidary shop examines some beautiful gemstones, while a fun, hands-on investigation demonstrates how solid crystals can be made from a liquid.
