Activities

Earth Science.5

The student will investigate and understand how to identify major rock-forming and ore minerals based on physical and chemical properties. Key concepts include· Uses of minerals

· Properties including hardness, color and streak, luster, cleavage, fracture, and unique properties

Saltville has vast deposits of salt, (NaCl), and gypsum (CaSO42H20 or hydrous calcium sulphate). Both are evaporates left by an ancient sea. Limestone is also plentiful in the area. These have been used to produce rock salt, baking soda, chlorine, hydrazine, wallboard, dry ice, etc. Observation of the rocks and minerals in the Geology exhibit. Identification of the minerals and discussion of their uses.

Earth Science.6

The student will investigate and understand how to identify common rock types based on mineral composition and textures and the rock cycle as it relates to the transformation of rock types. Key concepts include· Igneous (intrusive and extrusive);

· Sedimentary (clastic and chemical); and metamorphic (foliated and unfoliated) rock

The Geology exhibit has examples of each of the types of rocks listed in the SOL. Observation of the rocks in the Geology exhibit.Discussion and identification of the rock types observed.

Earth Science.7

The student will investigate and understand the differences between renewable and nonrenewable resources. Key concepts include· Fossil fuels, minerals, rocks, water, and vegetation;

· Resources found in Virginia;

· Environmental costs and benefits.

The Geology exhibit contains samples of coal and related sources of fuel.Salt was a vital natural resource, especially during the 19th century. Vast amounts of wood were used to fire the furnaces for salt production. As a result, the hills were bare for miles. Discussion of the salt and gypsum production in Saltville.

Earth Science.8

The student will investigate and understand geologic processes including plate tectonics. Key concepts include· How geologic processes are evidenced in the physiographic provinces of Virginia

· Processes (faulting, folding, volcanism, metamorphism, weathering, erosion, deposition, and sedimentation) and their resulting features; and

· Tectonic processes (subduction, rifting and sea floor spreading, and continental collision)

The Saltville Fault, a 450-mile fault beginning in Craig County in Virginia and stretching into Alabama, runs underneath Saltville. Observation and discussion of the fault line on the interactive valley model.Observation of the actual fault approximately half a mile from the museum.

Earth Science.9

The student will investigate and understand how freshwater resources are influenced by geologic processes and the activities of humans. Key concepts includeDevelopment of karst topography There are numerous sinkholes in the Saltville area. (an example of karst topography) Observation of the aerial photos of the large sinkhole in the area. Discussion of various causes of sinkholes.

Earth Science.10

The student will investigate and understand that many aspects of the history and evolution of the Earth and life can be inferred by studying rocks and fossils. Key concepts include· Traces or remains of ancient, often extinct, life are preserved by various means in many sedimentary rocks;

· Superposition, cross-cutting relationships, and radioactive decay are methods of dating bodies of rock;

· Rocks and fossils from many different geologic periods and epochs are found in Virginia

Every aspect of Saltville’s existence has been influenced by its geology. This is documented in all of the exhibits at the museum.During Spring 2002, the Saltville Exhibit Hall is showcasing an exhibit of locally recovered fossils which spans the geologic ages of the earth. For more information, click here. Observation and discussion of the Geology exhibit.Tour of the exhibit, “Fossils: Traces of the Ages”. Worksheets and study guides are available to teachers.

Biology.7

The student will investigate and understand bases for modern classification systems.Key concepts include

· Fossil record interpretation

The museum has an extensive collection of fossils on display.During Spring 2002, the Saltville Exhibit Hall is showcasing an exhibit of locally recovered fossils which spans the geologic ages of the earth. For more information, click here. Observation and discussion of ice age mammal fossils.“Dig It” Exhibit – contains various fossils which can be uncovered.

Tour of the exhibit, “Fossils: Traces of the Ages”. Worksheets and study guides are available to teachers.

Biology.8

The student will investigate and understand how populations change through time. Key concepts include· Examining evidence found in fossil records; The museum has an extensive collection of fossils on display.During Spring 2002, the Saltville Exhibit Hall is showcasing an exhibit of locally recovered fossils which spans the geologic ages of the earth. For more information, click here. Observation and discussion of ice age mammal fossils.Tour of the exhibit, “Fossils: Traces of the Ages”. Worksheets and study guides are available to teachers.
Chemistry.6 The student will investigate and understand how basic chemical principles relate to other areas of chemistry.· Environmental chemistry Olin Chemical Corporation and U. S. Gypsum produced a variety of products from the natural resources in the area. (soda and chlorine from the salt, etc.) Discussion of the various products produced in Saltville from the resources available here.

Programs can be tailored to meet the specific needs of your students. Contact the museum at (276)-496-3633 or by email at MOMA@NETVA.COM to discuss the programs available or to schedule a field trip.
