Stalactites and stalagmites are deposits. They are usually formed by calcite which is a mineral consisting of calcium carbonate. They are less frequently overgrown by aragonite which is orthorhombic calcium carbonate. In addition, they are rarely grown by gypsum which is hydrated calcium sulfate. This is because of the precipitation of calcite which raises the ratio of magnesium to calcium in the solution. This is enough for aragonite to become stable. In addition to this formation, water drips or flows from fractures on the ceiling of the cave. When this water evaporates, the limestone appears to have flowed downward. Some of it doesn’t evaporate until it has fallen through the air and lands on the floor. This water that flows is slightly acidic as well. If a stalactite touches a stalagmite, it forms a column. Stalactites and stalagmites may be formed up to one million years. They have a variety of shape and color which makes them unique. Their growth rates are so slow that if they are once broken, they can’t recover during a human life span of time. 2 Nails Heavy Cotton String 2 Large Jars || [] [] [] [] [] [] ||

Kevin Simonsen __Stars: How Elements are Made__
||  ||   ||   ||   || In 1054, Chinese astronomers recorded what they called a “guest star” in the constellation of Taurus, the Bull. Today we know that this guest star was a star explosion called a super nova. Inside the exploding star were most of the first 26 elements in the periodic table. These first elements included simple elements such as helium and carbon. During the explosion, other elements were created as well. After the explosion, the chemicals in space combined with each other to form ions and molecules. These elements traveled in space and ultimately ended up in planets like Earth, being part of everything we see around us and ourselves. || Materials: Black &Grey Poster Paper Glitter Styrofoam Paint Cotton Balls String Stars Tooth Picks || http://www.nmm.ac.uk/explore/astronomy-and-time/astronomy-facts/stars/what-is-a-star http://www.nasa.gov/worldbook/star_worldbook.html http://knol.google.com/k/supernova# http://www.universetoday.com/guide-to-space/stars/what-is-a-star/ http://www.duke.edu/~teb/stars/supernova.html http://www.space.com/supernovas/ ||  ||   || Type in the content of your page here.
