Body systems interact to make the human body the most complex machine ever built. With all the amazing, intricate facets of the body, how do all of the systems work together? Students will learn about how the nervous, reproductive, digestive, excretory, circulatory, respiratory, muscular, immune and skeletal systems work together to allow humans to successfully perform all of their daily activities. Vivid graphics and images illustrate the interrelationship of the body systems. One of ten volumes in the Human Body in Action DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Life Science: structure & function in living systems, reproduction & heredity, regulation & behavior, populations & ecosystems, and diversity & adaptations of organisms. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
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.
36" x 24" full color laminated poster.
This poster begins by defining a mineral. It then expands on that by exploring atoms, molecules, and crystal structure. The various crystal structures are explained. This is followed by an excellent summary of the mineral classes.
Mineral collectors and students want to identify their specimens. However, specimens of the same mineral can vary greatly in appearance, which can make that a daunting task. Identification is based on a number of properties.
This poster provides an outstanding introduction to those properties: hardness, habit, luster, cleavage, specific gravity, color, streak, and fluorescence. Illustrations are used to explain principles. Photographs of truly outstanding specimens are used as examples.

Provides a primary presentation of the basic rock types. Includes five each of igneous, sedimentary and metamorphic rocks, totaling 15 specimens, approximately 1.5" x 1.5". Grades 6-12. Ages 11-18.
Inquiry-based activities covering the basics of electricity. Perform a variety of hands-on investigations to study the properties of electricity. Students will explore the concepts of electric currents, open and closed circuits, and series and parallel circuits. They?ll also investigate static electricity using an electroscope. The students will apply the knowledge gleaned from these activities to classify materials as either conductors or insulators of electricity and electrical power. Your students will understand concepts of electrical charge, current, resistance and voltage. Understand the concept of electric circuit and power. Distinguish between resistors in series and parallel. Classify materials as electrical conductors or insulators. Identify cases from everyday life where electricity is being used. Class Size: 40 Students. Grades 7-10
