We are the Martians: Connecting Cosmology with Biology
For many thousands of years, human beings have been asking themselves whether they are more frightened of being alone in the universe or of the thought that there is someone else out there. Over the past few decades, however, we have moved from imagination to action, exploring the cosmos using new techniques, often with surprising results. Numerous fascinating but little known facts have emerged – for example, that every year many rocks from Mars fall on the Earth, that one of our amino acids has been found in the coma of a comet, and that some of the known thousands of extrasolar planets are similar to our own.
Did you know that the whole world lies at your feet? Really! Rocks and minerals are like little windows on the inner workings of Planet Earth. You just have to know where to find them and what you are looking at. That's where Dig It! comes in. Filled with hands on activities and fun facts, it'll teach you the basics of rocks and minerals and how they make a difference in just about every part of your life. You'll also find tips on finding and building a rock collection of your very own, and journal pages for keeping a record of your finds.

Bill Nye discusses the forces that affect the surface of the Earth in Bill Nye the Science Guy: Rocks & Soil. He explains that any of these forces can be violent, as in earthquakes and volcano eruptions, while some transform the Earth over a long period of time. The Science Guy looks at the inner workings of the Earth, and tells how rocks break down to help form soil. Nye inserts his usual trademark humor and parody into the scientific discussion to create a fun learning atmosphere.
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 All About Rocks & Minerals, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic...
