Conclusion about sparkly islands The geographical location of the South China Sea is very important. It is a route that fishermen must take‚ is rich in fishery resources and has very rich petroleum reserves. This has made it a bone of contention between the countries in the region‚ resulting in a never-ending conflict‚ especially in the Spratly Islands. Each littoral state has occupied islands as a means of declaring their sovereignty over them‚ so there is a high level of tension in the area

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

Prior to starting the Trinity TEFL course‚ I had little teaching experience in a classroom environment and only in my own language. I had little knowledge of the teaching techniques and methodology used to teach a foreign language and having to put theory into practice almost from day one seemed quite daunting. From one lesson to another I learnt different type of technique used in the classroom: using flashcards‚ elicit vocabulary‚ concept checking throughout‚ encouraging pair work and group

This post is the thoughts and points. after today’s lecture (8/31). In the novel‚ Like Water for Chocolate‚ by Laura Esquivel‚ love tensions and rebellion play a role into both the theme and the plot. The popular TV reality show and “soap opera” like content‚ The Bachelorette follows one lady looking for love in the mist of many male suitors. In this instance‚ Tita‚ is the contestant. She narrowed it down to her final two‚ John Brown and Pedro. Let’s get to know our contestants background. John Brown

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

9/22/13 I: Design Title: The Mass of Quartz Purpose: To determine the density slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls:
