Introduce your students to the world of minerals. Provide your class with a hands-on lesson in the formation and characteristics of minerals. Using the set of specimens provided, the students observe the distinct characteristics of minerals and perform a variety of tests to classify them with respect to hardness, streaking, color, luster, specific gravity and reaction to acids. They'll also grow their own microcrystals to understand how crystals form beneath the earth's surface and what environmental conditions are required. Your students will identify minerals based upon their physical properties. Determine the hardness of common minerals using Mohs scale of hardness. Examine the crystalline structure of minerals. Calculate the specific gravity of mineral samples. Predict the reaction of specific minerals to hydrochloric acid. Investigate how crystals form from liquids. Class Size: 40 Students. Grades: 7-10.
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.

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.
