Rocks and Minerals by Steve TomecekKids will gravitate to Steve Tomecek’s humorously illustrated guide, which surveys the earth’s astounding variety of rocks and minerals and the fascinating ways people have transformed them into usable materials. From talcum powder to silver jewelry, it all comes from inside this great big rock we live on. A high-interest topic for youngsters as well as an important segment of the elementary science curriculum, this book is in a kid-pleasing format and includes a bonus activity.

Identifying Rocks and Minerals/Differences Between Rocks and Minerals
Both are solid, inorganic, naturally-formed substances. However, there are mostly differences, like their uses, structure, and color. For example, minerals usually have a shape for a structure and are usually the same color, whereas rocks have no definitive shapes. Another difference is the presence of fossils. Rocks sometimes contain fossils, but no minerals have fossils. Minerals aid in bone and tooth foundation, blood coagulation and muscle contraction.
Rocks and Minerals Objectives. Describe the physical properties of rocks and relate them to their potential uses. Relate the properties of rocks to the possible environmental conditions during their formation. Lesson 7: Describing the Color of Minerals. Lesson 9: Exploring the Luster of Minerals.
A mineral is a naturally-occurring substance formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure and specific physical properties. Rocks do not have a definite chemical composition. Petrology is the scientific study of rocks while the the study of minerals is called mineralogy. Rocks are generally made of two or more minerals. A main determining factor in the formation of minerals in a rock mass is the chemical composition of the mass, for a certain mineral can be formed only when the necessary elements are present in the rock.
