Rock Candy Crystals free essay sample

Crystals are formed when atoms line up in patterns and solidify. There are crystals everywhere — in the form of salt, sugar, sand, diamonds, quartz, and many more! To make crystals, you need to make a very special kind of solution called a supersaturated solid solution. Here’s what that means: if you add salt by the spoonful to a cup of water, you’ll reach a point where the salt doesn’t disappear (dissolve) anymore and forms a lump at the bottom of the glass. The point at which it begins to form a lump is just past the point of saturation. If you heat up the saltwater, the lump disappears. You can now add more and more salt, until it can’t take any more (you’ll see another lump starting to form at the bottom). This is now a supersaturated solid solution. Mix in a bit of water to make the lump disappear. We will write a custom essay sample on Rock Candy Crystals or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Your solution is ready for making crystals. But how? If you add something for the crystals to cling to, like a rock or a stick, crystals can grow. If you â€Å"seed† the object (coat it with the stuff you formed the solution with, such as salt or sugar), they will start forming faster. If you have too much salt (or other solid) mixed in, your solution will crystallize all at the same time and you’ll get a huge rock that you can’t pull out of the jar. If you have too little salt, then you’ll wait forever for crystals to grow. Finding the right amount takes time and patience.

Free Essays on Colonialism of Africa

Although there had been a British and greater European presence in Africa prior to the last two decades of the 19th century it was primarily coastal and revolved around the slave trade. With the abolition of the slave trade within the British Empire in 1803 and a complete abolition of slavery across the empire in 1834 there was little interest in Africa by Britain until the end of the century. This lack of interest in Africa did not include The Cape Colony though, which the British gained at the end of the Napoleonic Wars and which served a key role in outfitting ships on the British trade route to India. The role and importance of Africa to the British soon changed though do to imperial competition with France and Germany. Germany under the aggressive policies of Bismarck set out to take a leading role in Africa and catch up to other European powers such as Britain and France in terms of empire by gaining new control over territory and expanding their spheres of influence. Other important factors made Africa the hot spot for British and European expansion including the discovery of gold in the Transvaal and diamonds in the Orange Free State, the palm oil industry in Nigeria, scientific discoveries such as the way to treat malaria, and the mapping and exploration of the previously mysterious African interior early in the 19th century. In order to explore the nature of British expansion in Africa Porter’s The Lion’s Share and T.O. Lloyds The British Empire 1558-1995 are indispensable texts. Using their information on British expansion throughout Africa as a foundation it becomes possible to break down the period of greatest growth between 1880 and 1900 by analyzing British role in Africa prior to 1880, the external roles that competitors such as Germany and France had in forcing England’s imperial hand coupled with the internal economic drives for procuring areas of Africa, and the special case and significance of the Cape Co...

Media Ethics class - Essay Example Definitely, this is a bit misconstrued given the very personal nature of the relationships revealed from the start. However, the fact that Nev was already aware of the fact that something was â€Å"amiss† may suggest that they only wanted to get to the bottom of the story, â€Å"see the story through†. In this regard, I would consider their decision to travel to Michigan as an ethical act. This position is informed by the sensitivity and relevance of the issue at hand. Facebook is currently the most subscribed form of social media( Plaisance 167 ). All persons who subscribe to it have different goals as evidenced by the documentary, therefore, it would be important for the media to educate the masses on this aspect. This way, the media plays its critical role which is educating people on the various perspectives and the widespread intentions of people taking to social media. I look at the decision to travel to Michigan as a way of providing the reality check and bringin g to the viewers the intrigues and deceptions that can take place in the social media. This way, the public is informed and hopefully individuals are able to take due caution in interacting with strangers in social media. This ethical stance is informed by Jeremy Bentham’s and John Stuart Mill’s utilitarianism theory. The theory asserts that the right course of action is that which maximizes utility it is that which delivers greatest good to the greatest number. In this case, Nev and Ariel upset a few people, the Abby’s family, to educate the entire public on the deceptions and misrepresentations that can be carried on social media.

Further, this view is very much in line with Plaisance thoughts on the media people who must recognize that they are creatures of community and must take the responsibility towards others as we are all interconnected and must care for each other (Plaisance
