Rocks & Minerals by Chris Pellant

Created in association with Smithsonian Institution, this authoritative guide features more than 500 rocks and minerals. Packed with photographs and details on characteristics, distinguishing features, and more, Smithsonian Handbooks: Rocks and Minerals makes identification easy.

Designed for beginning and experienced collectors alike, this guide explains what rocks and minerals are, how they are classified, and how to start a collection. Look up different rocks and minerals, and find clear, annotated photography to pick out the key distinguishing features. Learn the differences between igneous, metamorphic, and sedimentary rocks, and reference the glossary for many more technical and scientific terms.

Smithsonian Handbooks: Rocks and Minerals is filled with information about characteristics, colors, unique attributes, and more, making it one of the clearest identification guides for rock and mineral enthusiasts.

Earth Science for Kids: All About Rocks and Minerals

How are rocks the same and how are they different?

Students list the difference between rocks and minerals. It is a model which explains how one type of rock can become another type of rock if the environment where the rock "lives" changes. This environmental change may cause the rocks to melt, eventually forming a new rock. In the first grade, it is difficult for the students to understand all the processes of the Rock Cycle, but an explanation of the environments where rocks can form will help students to understand how rocks are "recycled. Minerals make up rocks.

It is important that your students begin to understand that rocks are made of minerals. Different rocks have different characteristics because of their minerals, the ways in which the rocks were formed, and the processes that acted on the rocks since they were formed. In this first investigation, your students will use their senses to investigate some of the physical properties of different types of rocks. They will then use their observations of the rocks to identify a particular rock from a collection. This investigation is considered generally safe to do with students. Please also review the investigation for your specific setting, materials, students, and conventional safety precautions. To introduce students to rocks, ask students to gather around a collection of rock samples of different types, sizes and shapes of rocks big chunks of granite, sandstone, limestone, marble, etc.

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. Some of them are also needed for nutrition by humans.

Let's start at the beginning …

Rocks are all around us. You can see rocks inside your house, in your yard, on your street, on a country road, everywhere you look. Statues, chalk, marble, pencil lead, sandpaper, glass, tombstones, bricks, the walls of your room, mountains, pebbles, soil, and volcanoes are all rocks!! Humans have used the metals and minerals in rock since the beginning of civilization. Rocks are used to build homes, an aluminum baseball bat, a washing machine, video games, airplanes, cars, and jewelry! Rocks aren't always solid.

Although the research base for geologic misconceptions is not as extensive as that of other disciplines within earth and space science, it is clear that students and teachers alike hold a wide range of incorrect ideas about rocks, minerals, and the rock cycle. To promote accurate scientific instruction, it is important that teachers are cognizant of their own understanding and seek to continually improve their content knowledge. Formative assessment can provide a great deal of insight into student thinking before, during, and after instruction. Finally, teachers should be metacognitive practitioners and reflect on how their methods of instruction may lead to the formation or strengthening of existing misconceptions. Geologic misconceptions can take many forms — the language used to define and describe specimens, relevant properties for classification, the rock cycle, and geologic time.

The Earth was formed about 4. The planet was so hot that the entire Earth was molten or liquid. As the Earth cooled, the lightest materials floated to the top and the heaviest materials sank to the center. The outer part of the Earth, the crust, consists of the lightest rock. Most of the granite on the continents has, over millions of years, been broken down, transported, and deposited into sedimentary rock. These layers of sedimentary rock vary from miles thick to nothing in some areas like the Canadian Shield of North America.
