In its best known form, it is a soft fine-grained white rock, consisting of almost pure calcium carbonate (limestone), pieces of which are used for drawing. It is usually applied dry to paper and because it smudges easily it is easily mixed and blended. definition Topic 2 Subtopic 1 Subtopic 1 Subtopic 2 Subtopic 2 Topic 3 Topic 3 Picture Picture Topic 4 Topic 4

Web. 29 Oct. 2013. <http://en.wikipedia.org/wiki/ Chalk>. previous uses information When you draw with chalk on the sidewalks it will eventually be washed away by rain and go through the local sewers, and end up back in the ocean. When it returns to the ocean it will continue the calcium cycle, and contribute to the dissolved marine calcium. Then, the marine salts will contribute to the other marine shells or remain undissolved which will, either way, create a new limestone or gypsum bed millions of years from now. Use of Chalk Chalk Chalk didn't become a standard in a classrooms until the nineteenth century. Chalk used to be used in agriculture to raise pH levels in soils with high acidity. Antacid properties make chalk ideal for polishing and cleaning. Toothpaste, for example, contains small amounts of chalk. Chalk is also used in fingerprint powder. Manufacturing Chalk Citations Calcium Carbonate is the main component in chalk. Calcium Carbonate is a form of limestone, which is formed when plankton skeletons decompose and turn into coccoliths, then the coccoliths accumulate and form sedimentary layers. The base component in pastel chalks is Calcium Sulfate, which is derived from a mineral evaporate of ocean brine called Gypsum. Pastel chalks also contain clays and oils for pigment. Quarry the limestone - The land over the limestone deposit must be removed with bulldozers and scrapers, then holes are drilled into the rock and explosives are placed inside to blow the rock apart. Pulverize the chalk - The limestone has to be transported to the crushing machine to pulverize the limestone to meet the chalk industry's standards (has to be primary crushed and secondary crushed). Then the chalk has to be wet ground to wash away the impurities. Rotating steel drums with steel balls inside pulverize the chalk until it's very fine and easy to write with. After the chalk is ground, it's sifted over vibrating screens to make even smaller, finer particles. The particles are mixed with water, shaped and cut to the proper length. The chalk is then placed into an oven, baked to at 188 degrees Fahrenheit for four days and cut to 80 millimeter lengths.

What is Blackboard? Blackboard is a tool that allows faculty to add resources for students to access online. Powerpoint, Captivate, video, audio, animation, and other applications are created outside of Blackboard and added into Blackboard courses for students to enhance teaching and learning efforts. ...Not just a cool place for chalk to hang out Blackboard Communities...

Transcript: Powerpoint is a TERRIBLE way to teach maths and physics! It would be a lot easier if the lecturer wrote on the board, instead of doing all the lectures on PowerPoint. I always feel myself dropping off to sleep when the lights dim and powerpoint starts up. Chalk and talk please I find it impossible to follow powerpoint presentations for some reason. Powerpoints are very hard to take notes from It is hard to follow complex mathematical concepts on powerpoint slides. Some more SOLE comments With 7 students in a 15-seat lecture theatre we had to adopt new technology! Video-conferencing to an overflow room Students see a high-resolution image of the lecturer and blackboard Electronic media on a separate screen Number using the overflow steady at ~15 Blackboard is used for all lecture notes, PowerPoint presentations, problem sheets… Though students preferred our previous intranet Slow to adopt quizzes & discussion boards Metric for summer revision PowerPoint has been tried by many lecturers with a mixed reception... Material done on the boards is supported well by powerpoint material Use of powerpoint slides worked very well The sections by XXX were excellent, and were examples of how powerpoint should be used as a learning aid. The powerpoints made the lectures very well structured I liked the powerpoint with diagrams. Physicists have a reputation for resisting innovation “Chalk and Talk” is well suited to mathematical material Need to see a mathematical proof evolving step by step This is clumsy with PowerPoint or OHPs Blackboards allow students to see in real time where each piece of an equation comes from Blackboards give a running history that can be referred back to Blackboards allow a lecture to become theatre The students themselves prefer “Chalk and Talk” Physics departments and innovation?

Transcript: Calcium carbonate Limestone Chemistry with chalk Calcite is limestone mineral Calcite can be form in a way Calcite formula is CaCO3 Calcite is a very common and wide spread mineral with highly variable forms and colors What is chalk Pencil Cave art calcite Made of many chemical Mostly like stick or pencil calcium carbonate, copper, manganese, and fluorine Crush then turn into chalk There all kind of chalk. For example, there are colors chalk, art chalk, and normal chalk. My drawing from art class. ChALK Chalk How chalk is made I have a little chemistry with chalk. My chemistry with chalk is in art class this last semester. I have work with chalk in art class to draw a portrait of someone. That my only work of art I did with chalk in art. Chalk is also easier to work with and make the drawing look good in paper or street. limestone Found in or from seas and lake Shell for and animal Limestone mineral in them are called calcite
