Crystals are fascinating creations of natural beauty. Diamonds, gemstones, rose quartz, snowflakes, sugar grains, and table salt are all crystals. Grow your own crystals and explore these exquisitely ordered structures in a fun, creative way with six crafty experiments. This kit includes five different chemicals and other tools for growing crystals. Grow a crystal cloud inside a rainbow. Watch pink iridescent crystals form from a translucent solution. Grow long needle-shaped crystals. Mold plaster hearts and flowers and then grow a layer of pink crystals on them. Create the perfect solution to get crystals to form on a granite rock. A specially designed experiment station provides molds and growing basins for your crystal creations. After you have grown your crystals, store them safely in three clear, locking display boxes. Learn how and why crystals form, and tips and tricks for getting the biggest, most beautiful crystals. Full-color, 16-page experiment manual.

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.
From calcium to zinc, explore some of the many types of minerals that are used in common foods, vitamins, food processing and preserving. Six numbered specimens approximately 1.5" x 1.5" show the importance of our use of minerals for daily nutrition. Grades 5-12. Ages 10-18.
Contains 15 representative specimens of intrusive and extrusive igneous rocks, each approximately 1.5" x 1.5". Grades 5-12. Ages 10-18.
36" x 24" full color laminated poster.
This is an outstanding rock identification chart! The introduction explains that each type of rock is the result of a specific mixture of minerals subjected to a clearly defined geological process. It shows and describes the most common rock-forming minerals and variations that occur within rock types.
The bulk of the poster is divided into three sections, one for each rock type: igneous, sedimentary, and metamorphic. An illustration shows how they are made, and a photograph shows a natural formation. A dozen other photographs show representative specimens. Each is accompanied by an informative caption citing identifying characteristics and common variations.
A bonus section shows and explains some of the more specialized and popular rock forms, such as geodes, concretions, agates, and meteorites.
This is a great poster for earth science classes. Rock collectors find it invaluable for quick reference.

The 21 plastic fossils and detailed Laboratory Manual in this kit will let your students become practicing paleontologists. Kit conveys importance of fossil study to investigations in geology, history, mapping, and stratigraphic correlation. Grades 7-12.
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.
This 24" inflatable writable globe has a white background with outlined countries. The ball may be used over and over again with a wet erase marker (not included) to test your students geography skills.
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.
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.
