Separation of a mixture of solids Essay Example for Free

Separation of a mixture of solids Essay A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? When I began filling out my flow chart, I was slightly confused on how the actual experiment was supposed to work. After watching the separation and a few times trying some steps I understood the experiment. B.Discuss potential advantages or disadvantages of your proposed procedure compared to the one actually used. The filtered item with the paper took longer than expected to dry and I actually still had some wet particles on my paper. When performing these steps without direct supervision it can be hard to make sure you are doing things correctly. There could be many errors with measurement and all of the mixture could not be separated. C.How would you explain a sand recovery percentage that is higher than the original sand percentage? To explain this I would say that not all of the other mixtures were actually separated from the sand. D.What were potential sources of error in this experiment? The potential sources of error were in the weighing of the item and in whether or not the item was all the way dry or filtered. Final Conclusion: (Summarize the most important findings and what you learned from this lab) I learned that through various procedures, different pieces of mixtures can be separated and that each has its own distinct properties. If I were to simply look at a mixture I would not know that all of the items could be separated into their own category.

Witchcraft of the Past Essay -- Essays Papers

Witchcraft of the Past What images does the word "witch" create in a person’s mind? Most people would tend to think of an old woman wearing a black, cone-shaped hat, with a large mole on her face, and perhaps flying on her broom. This is the stereotype of witches, and although some witches of the past may have fit into this category, one must remember witchcraft is a religion with a variety of followers. On the Covenant of the Goddess website, the basic philosophy of witchcraft is stated in one simple sentence: "Our religion is not a series of precepts or beliefs, rather we believe that we each have within ourselves the capacity to reach out and experience the mystery – that feeling of ineffable oneness with all Life." 1 This website is devoted to finding the origins of witchcraft, specifically faith and reason, and how it has affected society over the past 700 years. In the thirteenth century, witches, then called cunning folk, "played a positive role in helping people cope with calamity."2 They provided hope to townspeople that through magical means, natural disasters might some how be avoided. The cunning folk provided this important service that kept village life moving ahead. Possession of these so-called magical powers made one an important member of village society. People in need of "security and influence, namely, the old and the impoverished, especially single or widowed women" most often made these claims.3 In the late thirteenth century, the Christian church "declared that only its priests possessed legitimate magical powers," and "those who practices magic outside the church evidently derived their power from the Devil."4 The church wanted to rid society of the witches’ influence, and thus witch-hunts began. .. ...tion." 8.

Time and Life

Everyone wants to be successful in their own, different way. It is a mutual dream shared by all, to be rich and famous. In my perspective being successful is much different, because money is not everything. To make goals and follow your dreams will lead you down the road to success. Their will be bumps along the way, and you might have to take the harder road, but if you are willing to work hard and never give up, you will be successful. Like everyone, I have many dreams and goals that I would like to see myself accomplish during my life. I want to go to a great college and discover myself, what it truly means to be me.Then I will decide what I would like to spend the rest of my life doing because I honestly believe that, at my age, I do not contain within me the experiences necessary to determine what I want to be or what I want to do with my life. Given the opportunity, I would go into the ? eld of science to study biology or engineering to ? gure out how and why things work, livin g or not. But who knows? I might end up in a totally different ? eld, because wherever my heart goes, I am sure to follow. I want to go to a top school to start with a strong support in the world and to use this foundation to build my life upon.If the building blocks of my future are too small, I will be con? ned to certain things and not others that I would be able to reach with a bigger, sturdier base in knowledge. This will create limitless opportunities that may result in a great job. I want a job that pays well enough so that I could support a family, if I so choose. I want enough money to pay for little things in life, those that create great memories, but not so much that it will go to my head and make me a person that has worked so hard just to see himself become corrupt and sel? h. Above all I want to thank my parents for starting me off in the right direction, they gave up so much for me, because they instilled these values in me and made me who I am today. They have helpe d me this far, and they will help me in the years to come. Without them I would be nothing, and I believe that this deserves much more than simple thanks. My decisions will affect my future, whether it be the near future or in the long run. Seeing as I cannot predict the future, I will just have to work hard and make the right decisions.The right thing is not always the easiest thing to do, but is necessary if you want to reach your goals. The only obstacle that I see in the way of my future is myself. I can do anything I want if only I put my mind to it. But if I make the wrong choice and slack off, it is only that much harder to reach your goals. Another thing between my future and myself is time. Everything changes over time so it is only natural to believe that my short-term goals will too. But the things time cannot change are life long goals.The things you see yourself doing when you sit down and think of all the wondrous things in this world that makes you think what a miracl e life really is. Life is a gift bestowed upon us, and it is our choice to determine where it goes. My goals are what make up my life, what keep me determined to ? ght for the next day and the drive behind everything I do. My family plays a huge part in who I am, and my values. I want more than everything in my life to be successful, and for those I care about to be successful in their lives too.

Thesis Preparation Have visualizations been a good tool to use in the world of Design? In my assignment, I will be looking at how the general use of certain software’s and digital technology has taken the world of architecture and Interior Design in another era.

At the moment, we are living in a world of advanced technology where everything is taught using digital technology, whether it be a mobile device, an iPad or a computer, in a preschool or third level facility.

Perhaps that could fall into the hands of the educators / professors in 3rd level college to change radically how they teach students or stick perhaps to the conceptual work teaching. In another article, â€Å"Visualization skills for the new architectural forms†, they discuss the amount of use of technology and whether it is having a profound effect on the concepts and the fundamental beings of being an architect. They argue if visualizations can replace the development which all architect usually manually solve. This is an interesting article as it mentions whether technology has either hamper or benefit the development of being an architect or a designer. ( Ashraf M.Salama and Michael J.Crosbie – Special Volume: Design Education: Explorations and Prospect for a better built environment – Visualization skills for the new architectural forms No.346-358 pp) â€Å"This development obviously raised challenging questions about architectural theory and perplexing issues for those concerned with the future of architectural education and its effect on the design process†.
