Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

The Twin Experiments was conducted by Josef Mengele‚ during World War 2 in Auschwitz. Dr. Mengle was a medical researcher who was fascinated with twins in specific. From the three thousand children that would be pulled from the masses of people upon arriving only about 200 survived. Age didn’t matter‚ yet most were children‚ and if they were really young their mother would be allowed to stay with them. The twins recieved "special" treatmeant as they were allowed to keep their hair and clothes. A

Hawthorne Experiment. Advantages: During the experiment the performance of the group has increased (Not because of improving conditions‚ but because of the communication and collaboration) Disadvantages: there were personnel changes‚ that is the workers hostile watching the situation changed for those who would like to work in such conditions (that is attended only those workers who are more willing‚ not all workers) Conclusion: This experiment showed that workers are willing to actively

Life in the Chesapeake Colonies The first successful British colonization of the Americas was in the Chesapeake area and anchored by Jamestown which was founded in 1607. The original colonists nearly didn’t make it‚ as it was a very difficult life for them. Moreover‚ the colonists founded many relationships that were both good and bad with various other groups so that they could make it through those first years. With great will and sheer luck the area has thrived‚ becoming the heart of the

The ‘Experiment’ by Dr Haskell portrays the unusual experiment that he conducted to compare his bare body and a Chickadees body in harsh freezing conditions. He decided to investigate it further because there was no logical explanation for a tiny bird to be able to survive in such conditions. He related his astonishment to the Bergmann’s rule‚ which states that larger animals will be found in colder climates and smaller animals will be found in warmer climates. Haskell found that the Chickadees

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

colonial one but it also differed wildly from other colonies set up by England. Before we can test the nature of the relationship between both England and Ireland‚ it would be a good idea to establish what exactly a colony is and what one means by colonialism. We will tend look at America and how it was colony and then highlight some Irish examples but also show how Irish Tudor relation were a different proposition to the New World. Colony‚ Colonial and Colonialism So what are these concepts
