Chemistry and Chemical Engineering - What is the Difference?

Chemistry and Chemical Engineering - What is the Difference?Before attempting to understand what difference there is between chemistry and chemical engineering, one must understand that chemistry is a branch of science concerned with the chemical and physical properties of substances. Chemical engineering is the branch of science concerned with the utilization of materials to create useful products and processes.For example, if a chemical engineer were required to make a formula for an ideal sugar-based fuel, he would need to use chemistry in order to design a chemical reaction that would react to the fuel. A chemical engineer is also required to use chemistry to create new products from raw materials, by combining and mixing elements, or by constructing products from their raw materials.A number of different types of materials exist within the world today; they are all made of one or more elements. In the above examples, chemical engineering could create many useful products from th e materials available, from gas to plastic, from natural gas to plastic bottles.There are several other differences between chemistry and chemical engineering that are very significant. In one example, chemical engineers make substances that can be used to create a product that has already been created by another chemical engineer, a substance which has been approved and added to the market to meet demands of its buyers.Whereas scientific chemistry concentrates on the properties of certain substances as they occur naturally, chemical engineering concentrates on their manufacture into products for sale. Some of the compounds created by chemical engineers are used in products within the industry, as well as in medicine and other areas of science.Some scientists and engineers think that this difference between chemistry and chemical engineering could lead to different roles in society. The chemist is a very important part of society; a chemical engineer is not.With the advances in scie nce and technology over the last few years, it has become much easier to perform scientific and engineering research and develop better products in the industry. Hopefully, this will lead to a future where people are able to create better products by using these advancements in science and engineering.

Another Pre Pre SAT Test

Another Pre Pre SAT Test The College Board, the creators of the SAT, introduced a junior version of the exam for eighth graders in 2010 called the ReadiStep, according to an article in theNew York Times. The ReadiStep is a two-hour test and has questions written in the same style as the PSAT and the SAT. The test is scored 2-8 for each section, similar to the 20-80 score range on the PSAT and SAT. Nearly 250,000 students have already taken this test in the fall of 2010, most of whom are in Texas because the state education department offered to cover the tests $8 charge for every student as part of a larger college-readiness program. The College Board created this test to help schools and districts better measure middle school students potential not just on entrance exams but also for college-level work. ReadiStep is designed to be very similar to the PSAT and SAT, said Glenn B. Milewski, executive director of ReadiStep and the PSAT.It is essentially a learning tool. Its intended to help schools and districts improve their curricula and instructional practices. The PSAT is the qualifying exam for National Merit scholarships. However, opponents of the test are arguing that it creates a lot of unnecessary stress to many students at such a young age. Some believe that districts and states are becoming too obsessed with properly assessing students. They question this tests ability to properly determine how well a student will perform on the SAT four, five years down the road. Its just deceptive as can be, said W. James Popham, professor emeritus in the graduate school of education at the University of California, Los Angeles. It conveys the notion that your child has these strengths and weaknesses, when theres no way to tell. Popham is actually in favor of early testing for students, but not the ReadiStep. Some even believe that the College Board is trying to take advantage of over-zealous parents, hoping to get their students involved in the competitive college-application process early. Where does it stop? asked Louis J. Kruger, an associate professor in the school psychology program at Northeastern University in Boston. If you can prepare them in eighth grade, cant you prepare them even earlier than that? Theres already considerable stress and anxiety today in public school students in regard to being assessed, and the assessment as being a gateway to college. The test has three, 40-minute sections in mathematics, critical reading and writing. Students are scored 2-8 on each test with 2-2.9 being a low score and 6-8 being a high score. Students also receive suggestions on how to improve their learning based on their scores. The test is still too young to measure any of its results on students PSAT or SAT scores years later. However, students who take the PSAT twice scored about 120 points higher on average on the SATs three subsets than those who did not. Typically, students who take the PSAT multiple times are more dedicated to education than those who do not.
