This title is suitable for ages 9 to 12 years. Dig into our ever-changing earth and discover how geology rocks your world every day. Explore planet Earth from its red-hot center to the top of the tallest volcano (and on into outer space!). Dig in, build, and create all things geologic with hands, mind, and feet. Be in charge of your own thoughts, ideas, and actions about the earth and how we use its treasures. For sure, you'll never feel the same about the pebble in your shoe, the pencil in your desk, or the coins jingling in your pocket.
