Sherlock Holmes Chemistry Experiments
Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests, such as solubility, pH, or color tests. In our group we had to test come common powders such as Alkali-Seltzer, baking soda, flour, Vitamin C (ascorbic acid), and salt. Other chemicals that were used to do this experiment were vinegar, and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper, and 5 test…...

Psychology Essay Examples A Level
One reason that studying memory and organisation may be interesting is because the area was neglected, up until the 1990’s, when psychologists became interested in how an ‘enormously important but complex facility operates in people’ after being stimulated by the attempts to provide information about computer systems and how information is organised.( R.Gross, Hodder and Sloughton) One theory in relation to memory suggests that organisation may occur at two separate stages of memory. Meyer said ‘to remember is to have…...

What Is A Paper Helicopter
If the mass of the paper helicopter increases, then the drop time of the paper helicopter will decrease because the paper helicopter with the greater mass will take a longer time to reach terminal velocity ( when there is a balance of forces and thus zero acceleration) which results in a shorter drop time because the object is still accelerating. The mass of the paper helicopter will be measured by using 5 paperclips of each . 7g and the same…...

Detecting Oxygen on Planets
If one can tell if a planet has oxygen on it based on its bright line spectra, research could be done to tell if people can live on the planet or not. This would be a huge advance in science if it was possible to tell if people can live on other planets by knowing the elements on the other planets. This would solve the problem of the world becoming over-populated and would help prevent the spread of disease. Introduction-…...

During those high-carbon-dioxide times, lands with fewer stomata will have an advantage and will be common. On the other hand, when carbon dioxide levels are low, plants need many stomata in order to scrape together enough carbon dioxide to survive.

Introduction Motor skills must be taught in order to be performed proficiently (Logan, Robinson, Wilson, & Lucas, 2012). The speed-accuracy trade-off is the relationship between how fast a movement is completed and the accuracy of the movement. Hsieh, Pacheco and Newell (2016) discuss that when completing a movement task quickly and increasing movement speed there is greater chance of making more mistakes and being less accurate. Freestone, Ferdinands and Rooney (2015) conducted an experiment to test the speed-accuracy trade-off with…...

Hooke’s Law Experiment Conclusion
The aim of this experiment is to investigate Hooke’s law for simple springs of rubber. The relationship between a load force and a light spring (F=k. x) was first determined by Robert Hooke in the 17th century. Where F is the force applied to the spring, k is the spring constant, and x is the extension of the spring. Hooke’s law states that when an elastic material is subjected to a force, its extension (x) is proportional to the applied…...
