Science Toys Make toys at home with common household materials, often in only a few minutes, that demonstrate fascinating scientific principles. To make it easier to build some of the toys described in the book we have a catalog of parts and science kits. Some of the catalog items are: Twitter: sqfield

How is Soil Formed Parent Material Parent material is basically the earthen materials that make up the soil. It can be rocks or volcanic deposits or sediments. The parent material is largely responsible for a soils texture and sometimes a soil’s alkalinity. As this material becomes exposed to the surface they begin to erode and become altered chemically. The type of soil that forms is a result of the available rock, and which minerals are contained within.
Metamorphic minerals are those that form only at the high temperatures and pressures associated with the process of metamorphism. These minerals, known as index minerals, include sillimanite, kyanite, staurolite, andalusite, and some garnet. Other minerals, such as olivines, pyroxenes, amphiboles, micas, feldspars, and quartz, may be found in metamorphic rocks, but are not necessarily the result of the process of metamorphism. These minerals formed during the crystallization of igneous rocks. Metamorphic rock
Sedimentary rock Middle Triassic marginal marine sequence of siltstones (below) and limestones (above), Virgin Formation, southwestern Utah, USA Genetic classification Based on the processes responsible for their formation, sedimentary rocks can be subdivided into four groups: clastic sedimentary rocks, biochemical (or biogenic) sedimentary rocks, chemical sedimentary rocks and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes. Clastic sedimentary rocks Clastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest. Clastic rocks are composed largely of quartz, feldspar, rock (lithic) fragments, clay minerals, and mica; numerous other minerals may be present as accessories and may be important locally.
List of rock types Igneous A sample of andesite (dark groundmass) with amygdaloidal vesicules filled with zeolite. Diameter of view is 8 cm. Andesite - an Intermediate volcanic rock Anorthosite - an intrusive igneous felsic rock composed predominantly of plagioclase
Igneous rock Geological significance Igneous and metamorphic rocks make up 90–95% of the top 16 km of the Earth's crust by volume. Igneous rocks are geologically important because: their minerals and global chemistry give information about the composition of the mantle, from which some igneous rocks are extracted, and the temperature and pressure conditions that allowed this extraction, and/or of other pre-existing rock that melted;their absolute ages can be obtained from various forms of radiometric dating and thus can be compared to adjacent geological strata, allowing a time sequence of events;their features are usually characteristic of a specific tectonic environment, allowing tectonic reconstitutions (see plate tectonics);in some special circumstances they host important mineral deposits (ores): for example, tungsten, tin, and uranium are commonly associated with granites and diorites, whereas ores of chromium and platinum are commonly associated with gabbros.

EDTEC 670 - Exploratory Learning Through Simulations and Games
| Instructional Objective | Learners & Context | Object of Game | Game Materials | | Time Required | Rules | Design Process | References | Learners will be able to identify a variety of factors and processes pertaining to rock formation, rock types, and the rock cycle. The overall instructional goal of The Rock Cycle Race is to provide practice and reinforcement for sixth-grade science students regarding this instructional objective. In the state of California, curriculum frameworks focus on teaching Earth Science at the sixth-grade level (http://www.cde.ca.gov/board/pdf/science.pdf). The Rock Cycle Race
Dimensions of need - The soil Soil covers most of the land surface of the earth in a thin layer, ranging in thickness from a few centimetres to several metres. It is composed of inorganic matter (rock and mineral particles), organic matter (decaying plants and animals), living plants and animals (many of them microscopic), water and air. Basically, soil forms as rocks slowly crumble away. Air and water collect between the particles, and chemical changes occur. Plants take root, binding the particles together, shielding the surface from the elements, drawing up minerals from lower layers and attracting animal life.
-- home -- environment -- issues -- Rev 20051121,20060712,20070211, The situation on the ground fares much better with about 15kg carbon for forests and 3kg for grassland. But the animal content is very small, amounting to only 50mg per square metre. By comparison, the soil contains most carbon, at 10kg. Soil ecology

by Rachel M. Barker Rocks Tell the Story of the Earth The Earth is made of rock, from the tallest mountains to the floor of the deepest ocean. Thousands of different types of rocks and minerals have been found on Earth. Collecting Rocks
Show off your collection with these deluxe display boxes A Rock Box template (right click on this link, then Save Target As to a folder of your choice) can be used to make attractive boxes with room for labels for a thumbnail sized collection of rocks and minerals. The boxes are 1.5 x 1.25 inches, and are 1.6 inches high in the back. The boxes are easy to pick up, and labels can include a lot information about the rock or mineral.

No matter how much you know, there is always something new to learn about science. While your college courses may cover the basics, you can get a more in-depth look at a wide variety of topics from Internet resources such as these great documentaries. These selections will help you explore everything from the inner reaches of the human mind to the outer areas of our universe and just about everything else in between. Better yet, they’re all free to watch online so you can learn more without spending a dime. Health and Medicine These documentaries cover topics like health care, diseases, nutrition, nursing, and more so you can get great insights into health and medicine.
