The 15 fossil specimens in this collection illustrate the animal and plant evidence found in various strata. Representative fossils from this era are the oldest known, coming from the Cambrian through the Permian periods. Grades 7-12.
Fossils are historic blueprints -- remnants of plant and animal life that preceded us. In Fossils, students will examine molds, casts and imprints of various living things, and discover how scientists place the age of these ancient remains and the methods they use to preserve them for future generations. Find out how paleontologists discover fossils and what these discoveries tell us about the past. Take a trip to the Petrified Forest, and examine tree trunks that were turned to stone millions of years ago. A fun, hands-on investigation demonstrates for students how they can create four different simulated environments in order to test each for its ability to preserve remains. 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.
Fascinate your students with the study of fossils. Kit contains 5 sets of 21 plastic reproduction fossils that students can measure, identify, and classify according to geologic era using the included fossil key. Grades 6-12.
The fossils in this study unit help to illustrate the major processed by which a life form is preserved as a fossil. Some of the specimens will illustrate processes such as petrification, pyritization, molds and casts, and distillation. 15 natural specimens in a compartmented container. Grades 7-12.
15 fossil specimens represent geologic time from the Paleocene to the Recent. Some of these life forms date back 60 million years and are the forerunners of modern mammals. Grades 7-12.
Specimens in this collection are representative of the varied life forms which dominated this geologic era. The dinosaurs are well-known life-forms from this era. The 15 specimens are from three major periods: Triassic, Jurassic, and Cretaceous. Grades 7-12.
