rtSeptember 17, 2012 NAME: Shelby Collins TITLE: What’s That Mineral OBJECTIVES: The objectives of the Mineral Identification lab is exactly what the title of the lab says, identifying minerals. In this lab, after making detailed observations of important minerals by using a tool kit, knowledge of classifying common rock forming minerals is to be gained. BACKGROUND: Before undertaking this lab, there are important concepts that must be understood that help with identifying and exploring important minerals. To identify a mineral, their physical properties must be examined. Such properties are luster, the way light is reflected off of a mineral and whither or not it is metallic or non-metallic, hardness, the resistance to scratching, gravity, the density of the mineral compared to water, fracture, irregular surface breakage and cleavage, breakage on flat planes.
Both fields are much related to my current field because they both conduct physical laboratory testing and help to assist scientist. The only difference between these two jobs is that chemical technicians use chemicals to help conduct the test physical properties, and usually what comes with that is chemical training what they call this is MSDS. States that offer above average opportunities for Chemical Technicians are: * New Jersey- annual average of $52,780 * Texas- annual average of $52,120 * New York- annual average of $47,770 The annual salary for chemical technician
The data is contained in the Excel file Assignment 1 Data_Diamond Prices. [pic] The website www.adiamondisforever.com educates the layperson on the factors that influence the price of a diamond stone. These are the 4 C's: Carat, Clarity, Colour and Cut. CARAT (WEIGHT) The weight of a diamond stone is indicated in terms of carat units. One carat is equivalent to 0.2 grams.
Alex Marino Explain the methods used by historians and archaeologists to examine the past To learn about ancient civilisations, historians rely on the finds of archaeologists to propose theories about past events, and the lives of people from previous civilisations. For this to happen, archaeologists must find artefacts, which they do by two different types of excavation, the grid system and open area. Once a site is found, (usually by means of aerial surveying, satellite photography, field walking or a variety of geophysical methods) archaeologists use one of the two types of excavation systems to carefully uncover what lay beneath the surface. The grid system divides the site into boxes marked out on the ground which are numbered, the boxes are dug out, and separated by baulks, which are walls of soil between each box. This system allows archaeologists to examine the site vertically, and is based upon the Law of Superposition.
What the archaeologist finds absolutely amazing about a Stone Age society, I think is very interesting myself because it shows how people lived over thousands of years ago. The way that they prepped the stone for transport was very neat and interesting as well. Its pretty crazy how far they had to travel with a stone that weighed thousands of pounds that was pulled by people. Then more work was done for the final look and
Hass says that the stone-age hammer is now begin changes to steel hammer but the idea and the purpose remain the same .Hass(2208) support this key point of science by saying that “stone have taught us the shift in magnetic poles, and where to look for oil and metals”(p.57).Hass gives the use of the stone in politics; war, in metallurgy and in modern technology. (Hass 2008) A typical essay should ideally contain five paragraph which include an introduction with three key points and a concluding paragraph. The following essay by Hass is perfect replica of well-organized typical essay. Marius (1985) states that “you must pay attention to the thousands and thousands of details embodies of the essay and it really adds up to the essay. In the essay the statement was stated were very clear with all the necessary key points.
Recording data carefully and accurately is very important. Be sure to keep notes of experimental errors or difficulties during this experiment. Exercise 1 Length Measurements: For the measurement below carefully read the ruler to the best degree of accuracy. The reading you make in centimeters should have two decimals. In other words can you estimate the difference between 10.1 cm and 10.2 cm?
I found that I had more appreciation for the work mainly because of its size. The time, ability, intricate details and the overall creativity that must have gone into making such a small figure or stele is fascinating. Our docent also gave more background information on the history between Isis and Osiris. What a story! It was full of drama and suspense (definitely more than what is offered in the text.)
| School of the Built Environment | | The Strength of Plain Concrete | School of the Built Environment The Strength of Plain Concrete Introduction: In this report I will tabulate and comment on the results obtained in class and through the use of books and journals. I will carry out calculations in relation to the water/cement ratio and comparing the difference on the two methods used to test the strength (Compressive and Tensile splitting). Both tests are carried out on the same machine but using two different techniques to achieve the required results. Some results may not be with the average of standard tests carried out in the same way, due to some human error in the marking of which concrete was Non-Compacted and Partially Compacted on the day of the tests. But with regards this I think that the results and expectations have been quite accurate.
Usually the compass was used as divination tools. The spoon of the compass was made up of lodestone and the plates of it were made of bronze. From the looks of my research, they came up with a couple types of drills. They both were made around the time of 202 A.D. – 220 B.C. They had the seed drill and deep drilling.
