Over the course of its 4.5 billion-year history, Earth has undergone a great number of changes -- from a red-hot ball of molten lava to a planet with an environment capable of sustaining life. In All About Earth's History, children will trace the evolution of Earth and the organisms that populate it. Young viewers will take a peek deep inside the Earth, examining its varied layers while discussing how scientists use fossils to help map out the complex time line of events that has changed Earth over millions of years. A visit to the Grand Canyon examines the rock layers of this famous land formation, revealing how the climate of the region has changed over time. A lively, hands-on activity demonstrates how scientists use core samples to study the Earth. Part of the Earth Science for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
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.
When we try to move ourselves or other objects, a force is being created -- a push or a pull. Students learn about how forces are involved in everything we do and about the natural force that affects us every minute of every day. How does it help or hinder us in our everyday lives? With clear demonstrations and a fun, hands-on activity, these concepts are more easily understood. This program is one of 11 volumes in the Physical Science for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title correlates to the National Science Education Standards for Physical Science -- properties of objects and materials, position and motion of objects, and light, heat, electricity and magnetism. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
24"x 36" full color laminated poster.
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.

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 poster is an ideal partner to our Animal Kingdom Poster (16339). Both posters are great for life science classes, but the non-technical presentation makes them popular with both animal and plant lovers alike.

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.
