...* * * * * * * * * * IBM Corporation Page 1 * * * * * * * Describe the changes made by the eruption of Mount St. Helens. Write a volcano story based on a virtual trip to a volcanic area. Find and mark active volcanoes on a world map. List the factors and the stages in cave formation. Explain how stalagmites and stalactites are formed. Create a classroom cave complete with cave paintings. Define these terms: rocks, minerals, crystals, topsoil, humus, geologist, archeologist, fossil, volcano, cave, stalagmite, stalactite. Duration: Three to four weeks, 1½ to 2 hours each day. Instructional strategy: Students should work in pairs or sm...

...n, and a spokesperson. 2. Prepare boxes or trays with the ingredients for experiment. Make sure there is room to set aside each of the group's experiments for several days. 3. Explain that speleothems are cave formations. Speleothems differ in shape and colors. The most common known speleothems are stalactites, which hang from the ceiling, and the ones that grow from the floor are stalagmites. Speleothems are formed when water carrying tiny bits of dissolved rock enter an open space in a cave. When the water evaporates, the dissolved rock begins to solidify. The speleothems in Kartchner Caverns are beautiful because the cave has remaine...

...ble, or the introduction of outside air in the cave system by wearing away of the surface. As outside air enters the cave system, the water quickly becomes supersaturated with calcite, ending the dissolving process. This change usually marks the beginning of the deposition of calcite in the form of stalactites, stalagmites and other deposits, know as speleothems. The limestone rock in which Kartchner Caverns formed was faulted and created cracks and fractures which allowed water to seep in and begin the dissolution process. The water drains slowly downward and sideways towards a drainage point. As the water dissolved the limestone along...

  4.   Cave Conscious
...CARDS 1. You and a friend have found a sink hole which leads into a dark crevice. You decide to explore the hole and find yourselves in a big room with beautiful formations. You look around carefully and notice there are no other footprints, no trash, no writing or painting on the walls, no broken stalagmites or stalactites. This cave has probably never been explored by humans. Would you: * Tell the authorities about the cave, for examples the local sheriff or Forest Service or the caving club. * Cover it up and never go back. * Put a gate on the cave. * Keep it a secret and hope nobody else finds it. * Break off some speleothems. Retu...

...pes of caves such as sea caves, lava tubes and rock caves formed by erosion. * Read One Small Square Cave by Donald M. Silver. * Read Cave Life by Christiane Gunzy. * Compare bats with other animals or insects that live in caves. * Write a story about what it would be like to live in a cave. * Make stalagmites with a straw. Mix half a teaspoon of salt with one cup of water. Stir to dissolve. This is an example of how rainwater dissolves calcite. Take turns drawing a bit of the mixture into a drinking straw. Put a finger over one end to hold the mixture in and let several drops drip into a small dish. Let the water evaporate and observe...

...the class into pairs. Tell each pair to either draw a picture of a limestone cave or find a picture online. Then ask students to develop a detailed caption describing the chemical processes involved in the formation of the cave. Their cave image should include at least two unique features, such as stalactites and stalagmites, and students should write a description of how these features form as well. Students can write their descriptions on index cards and tape them below their image. Give students time in class to work on their projects. The Web sites below provide information.

Context: Our lithosphere continues to change as new landforms are created due to the movement of crustal plates. meteorite Definition: Matter that has fallen on the Earth from outer space. Context: Meteorites provided the rock material necessary for the Earth to grow. stalactites Definition: Deposits of calcium carbonate hanging from the roof of a cave. Context: The scientists investigated the stalactites hanging from the roof of the cave because they felt it would give them the age of the cave. stalagmites Definition: Deposits of calcium carbonate standing as pillars on the floors of caves.
