Ninety percent of Earth is made of minerals, natural materials that form the building blocks of the solid structures on our planet. In Minerals, students will examine the makeup of a mineral as they review such properties as hardness, luster, cleavage, streak, color and density. Learn where minerals can be found, and see the many different uses of these natural wonders, which include powder, tools, jewelry and medicine. A visit to an old silver mine shows how miners removed valuable silver ore over 100 years ago, while a fun, hands-on investigation demonstrates the crystalline structure of minerals. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Fossil fuels were formed millions of years ago as part of a natural process in which the remains of dead plants and animals were buried and placed under extreme pressure and heat. Coal, oil and natural gas are the most important fossil fuels. But what are they used for, how do we find them and what can we do to preserve our limited supplies? Students will find the answers to these questions and more in Fossil Fuels as they explore these nonrenewable resources of Earth. A fun, hands-on investigation demonstrates a creative alternative to using fossil fuels in the creation of plastic and a visit to an oil platform showcases how this valuable fossil fuel is pumped up from the bottom of the ocean. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Soil is the loose top layer of the Earth's surface, but what is it made of? How does it form? And why is it so important? In All About Soil, children will learn what components are needed to make the best soils for growing plants while discovering the important role that the forces of erosion play in the creation of this valuable resource. A visit to a grade school showcases a unique program that uses lunch leftovers and hungry earthworms to improve the soil in the school's garden, while an informative demonstration illustrates how sand is created from the continual erosion of rocks. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.

36" x 24" full color laminated poster.
Fossils were a mystery for thousands of years; then a few pioneering scientists realized that they were the remains or traces of once-living organisms.
Well-known bone-type fossils are actually rocks, the result of a process called mineralization in which minerals replace decaying tissue. This process is shown and explained. All of the other fossil types are also explored.
The rarity of fossils is dramatically presented, and strange things sometimes mistaken for fossils are identified. There’s an introduction to fossil expeditions and a summary of how fossils contribute to our understanding of the earth and life on it.
There is an especially helpful section on the relationships between fossils and geology. It covers the principle of original horizontality, the law of superimposition, the principle of faunal succession, the geological time scale, index fossils, relative dating, and absolute dating.
All of this is conveyed through detailed illustrations showing the processes, excellent photographs of representative specimens, and interesting and informative captions. This poster is a great aid to museum interpretive programs and is extremely beneficial in the study of both life and earth sciences.
24" x 36" full color laminated poster. This poster describes all ten divisions of the plant kingdom. Many representational species are shown including the four divisions of extinct plants.

This is a beautiful poster that is cherished by animal lovers, but it’s also an extremely useful educational tool, as it provides a comprehensive overview of the subject. It is divided into three sections, one for each type of mammal: the egg-laying monotremes, the pouched marsupials, and the familiar placental mammals. The latter is divided into 19 subsections, one for each of the orders. Superb, highly detailed illustrations show 98 representative species, including everything from the aardvark to the zebra.
This poster is an excellent way to introduce young children to a great many animals. However, its outstanding organization and presentation make it an invaluable reference chart for teachers, students, and professionals involved or interested in zoology, comparative anatomy, and taxonomy, the naming and classification of life forms.
