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.
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.
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.
The Earth Science Book Plus Series provides colorful teaching models and reproducible activity cards that teach children about earth science. The models are made of resilient, non-toxic, EVA foam, with removable pieces that stimulate problem-solving skills and develop small motor skills. The book covers contain background information, activities and extension ideas. Teachers can cut out the task card and use it in a learning center or as a group activity. The models are 10" x 14.5" x 3/4" thick.The Water Cycle model illustrates precipitation, evaporation, condensation and runoff. It shows that water is constantly reused and recycled and also illustrates how clouds are formed. Available in French. Grades K 6.
Investigate the rock cycle. What is a rock? What is the rock cycle? How do rocks form? How are they classified? Your students will answer these essential questions as they conduct a series of hands-on activities. Using the set of rock specimens included, they will observe the distinct characteristics of each type of rock and explore the igneous, sedimentary and metamorphic processes of rock formation. Your students will Understand the processes that form igneous, sedimentary and metamorphic rocks. Identify rocks by their physical characteristics. Classify igneous rocks as extrusive or intrusive. Classify sedimentary rocks as clastic, organic or chemical. Classify metamorphic rocks as foliated or nonfoliated. Model the effects of metamorphism on rocks. Relate different types of rocks to the processes of the rock cycle. Class Size: 40 Students. Grades: 7-10.
For use with 15297, 04235 and 98388 landform models. Set of 10 lab investigations workbooks includes 20 pages of activities involving students in locating and identifying features on the models, observing, speculating and recording the practical influence of geography upon economic and social activities of man.
For use with Fossil Chart 16785.
