) Hydrochloric acid, formic acid, nitric acid, hexanes, and toluene are all available in ACS grade through Carolina, which, with a bit of imagination, could turn into some spectacular experiments. (Toluene is, of course, a component in the production of TNT -- talk about an exothermic reaction.)
Laboratory equipment is also widely available. A simple search of the popular site Shopwiki.com reveals hundreds of beakers, pipettes, test tubes, alcohol burners, syringes, etc. More advanced items are also available, such as hot plates which automatically stir the contents of a flask placed on them, and a wealth of thermodynamic devices for pressure, temperature, and volume control.
Perhaps the best route for a truly interested young chemist to take is to begin with the CHEM 3000, working through its experiments and gaining insight, then proceed to a regime of self-education using the internet and libraries, and supplementing the capabilities of the CHEM 3000 with individually purchased chemicals and equipment. It is, apparently, still possible to burn one's house down and scare the wits out of one's mother while captivated by the wonders of chemistry; it is just not legal to sell a toy that provides the tools.
Empirically, it must be said that the progress of chemistry has not altogether halted for lack of chemistry sets to capture the minds of aspiring scientists....
However, it is logical that increasing regulation has stifled the progress of science in many areas, and has reached even into a scientist's childhood years. Regulation is important, certainly, but must be balanced by the need to foster the environment of free thought which made this country great in the first place. It was precisely this environment and attitude which allowed the leaps and bounds of social, political, and scientific development of the early and mid-20th century, and its opposite paradigm which hampered Soviet scientists throughout the cold war. To continue the streak of progression long enjoyed, the United States will one day have to return to those ideals; a prospect for which the advent of the CHEM 3000 gives at least some hope. After all, where would the world be if many prominent chemists had been unable to singe their own eyebrows off in the safety of a garage?

This happens as the magma chamber empties and a ring fracture occurs. This collapse often blocks the flow of magma but the heated interior still produces gasses and steam. Often, that steam and other gasses create a lake in the middle of the caldera similar to Crater Lake in Oregon or Glen Coe in Scotland. 8. WHY DO SOME VOLCANOES EXPLODE, WHILE OTHERS EMIT ONLY GASEOUS CLOUDS? Some volcanoes explode because
plate tectonics is responsible for changing continental landmasses through geological occurrences. Thousands of years ago the earth's surface has been hypothesized as one big landmass. The Earth's surface has been constant motion. "Fragmented into giant sheets of solid rock that glide atop a layer of hotter, more pliable material, the globe's appearance is forever changing." [Cowen, 1999]. These plates are semi-rigid, floated on flow of mantle. The plates measured around
continental drift to the present to explain the plate tectonics theory and how the Earth is forever shifting. Use some examples of past and present changes in the earth and the effect they caused. A newer theory in geological history, plate tectonics is used to explain many geological changes in the Earth, both past and present, and indicates how the Earth is forever adjusting and shifting, creating uplifts and
The very fact that the U.S.A. Patriot Act was renewed in 2010 (albeit with some modifications) shows alert citizens that public safety will most often trump personal privacy and in some cases, a person's civil rights. The Find Law organization alludes to the 4th Amendment in pointing out that the legal approach to warrantless searches has "been broadened" in the past few years. The Court has given the green
D.). A researcher may determine if a rock sample is sedimentary by examining whether it consists of grains. An igneous (from the Latin word for fire) rock, known as granite, consists of minerals like quartz, mica, and feldspar. "Igneous rocks come from melted rock material, or magma, that lies under Earth's surface" ("How can you tell," n.d.), forming when magma from inside the Earth travels toward the Earth's surface, or
