Aim: * The aim behind this science is to measure colours and to predominantly quantify the colour of light sources or objects from visual colour matches. (This means that the eye(s) are used as a tool to identify if the colour is identical or not. Scenario: I am a scientist, …

The rate of reactions is how fast something changes from its reactants to its products. For a reactions to occur, the particles must strike with enough energy. At the start of the practical only some of the reactions will have enough energy to strike with each other and create energy …

In this practical examination I am provided with a ‘100-volume’ hydrogen peroxide solution. Taking the ‘100-volume’ into consideration I have to plan two experiments that would enable me to determine the exact concentration of H2O2, in mol dm-3. Titration The first experiment I shall carry out will be a redox …

In this experiment, The Young’s modulus of copper will be mesured . Apparatus – copper wire 4m – G-clamp – polley on clamp -2*Wooden block – 2*rule (half meter and meter rule) – slotted mass with hanger 15 * 0.1 kg – adhesive label -micrometer screw gauge -safety goggles -polystyrene …

In the start of this assignment, I was told to choose one of seven other experiments to do. I chose the Counting cells using the pour plate method because I find it much easier than the other ones. In addition, I have had past experience therefore; it should be straightforward. …

Aim : To get any object to move in a circle you have to apply a force to it. Methods : With your experiment you don’t mention anything about controlling or measuring the force. All you have measured is the (average) period of the object moving in a circle. From …

The theme of the American Dream has not lost its relevance for more than a century. This theme runs through numerous works of literature, cinema, and fine art, and some creators devoted their entire life and all their creativity to the searching for the American Dream. John Steinbeck novel “Of …

Introduction Sodium carbonate and sodium hydroxide are both alkaline in nature. When hydrochloric acid is added to the mixture, sodium hydroxide reacts like this: NaOH + HCl —–> NaCl + H2O ………………….. (1) Sodium carbonate reacts with hydrochloric acid in a similar way but the reaction comes in 2 steps: …

Laboratory procedures and practices must be communicated in a laboratory, because to keep the risk as minimum as possible by storing the chemical products in an appropriate and safe manner. A staff member shall be responsible for all stored chemicals and their use. All products must be labelled so that …

The Robot Prototype is designed to test the user knowledge in term of understanding the task requirements to be performed. It tests the user in terms of the reaction, which may conclude if the user found enough information in the interface to deal with requirement. Three Prototypes are generated to …
