Scientific Method BY Jimmying The scientific Method 1 . Scientific Method- scientific investigation involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and result that validates or modify the hypothesis. Mechanist- Has belief that only natural forces govern living things, along with the rest of the universe. Vitality- believes that the universe is at least partially governed by supernatural powers. Cause and effect- the idea that the one thing is the result of another thing.
Induction- is a logical process by which all known observations are combined and considered before producing a possible answer. Deduction- is a logical process by which a prediction is produced from a possible answer to the question as. Experimental group- treated with or possess the independent variable Control group- that is not or does not Independent variable- the treatment or condition under study Dependent variable- event or condition that is measured or observed when the results are gathered. Controlled Variable- are all other factors, which the investigator attempts to keep the name for all groups under study.
Correlation- a relationship between the independent and the dependent variables. Theory- An opinion, a speculation or an assumption based on limited information or experience, not necessarily on facts. Principle- a source, or origin; that from which anything proceeds; fundamental substance or energy. Biogas- establishes the quantity of a substance that results in a defined effective dose that is, the dose that produces a particular effect. 2. The nature of scientific knowledge gives the basic understanding of the nature of science hat is occurring in the world and the reasons for its reliability. . Ask a question, do background research, construct a hypothesis, test your hypothesis by doing an experiment, analyze your data and draw a conclusion, communicate your results. 4. The purpose of an experiment shows the researcher or the tester to know the general principle being studied and the results that will be obtained. 5. When the results are repeatable, this does not mean that the treatment caused the result. However, the treatment and result are correlated. 6. In narrative form, and many of he details of the scientific method are understood and not stated.
Writing research articles allow scientists to share knowledge. Provides enough information so that other scientists can repeat the experiments or pertinent observations they describe. 7. Abscissas are used by the pharmaceutical industry to test new drugs. Agricultural firms determine the effectiveness of new fertilizers and her biocide’s with abscissas. Some industries measure the effects their waste discharges on aquatic organisms with abscissas. Food and Diet Analysis 1. Macromolecule- large organic molecules of which all cells are made Vitamin-
Necessary organic molecules that our bodies do not construct from other molecules. Mineral- Required in organic nutrients such as calcium and potassium. Carbohydrates- A simple sugar or a larger molecule composed of multiple sugar units. Macroeconomics- a single sugar molecules. Disaccharide- Two inconsideration Joined Polysaccharide- it more than two inconsideration Joined, the resulting large carbohydrate molecule. Lipid- oily or greasy compounds insoluble in water, but dissociable in unpopular solvents such as either or chloroform.
Protein- diverse group f macromolecules with a wide range of functions in the human body. Amino Acid- all protein are chains Calorie- energy producing potential of food. 2. Carbohydrates is used as the main source of energy by your body for all cellular functions. It includes simple and complex sugars derived from fruits, grains and starchy vegetables. Proteins provide basic structures for every organ system in the body. Also provides structures for enzymes which are organic compounds that serve as catalysts. Triglycerides provide energy during aerobic metabolism and stored in at tissues underneath the skin.
Cholesterol provides structure for steroid hormones. 3. To test if the starch is present in carbohydrates, lipids, and proteins the results come out as either positive or negative. The benedicts solution is used to test for simple carbohydrates. It is a blue colored liquid that contains copper ions, the solution will change to orange/red. The Logo’s reagent changes from yellowish- brown to dark purple/black. 4. Vitamins are necessary organic molecule that our bodies cannot construct internally, it is required from our diets, but small amounts.
Minerals are required inorganic nutrients such as calcium and potassium. Lipids provide long-term energy storage in cells among other functions and are very diverse. 5. 6. Proteins, carbohydrates, fats and oils, minerals, vitamins, and water. 7. Balance of grains, vegetables, and meats are required for healthy diet. The proportion of per cups is enough for a daily nutrients. Measurement 1 . Length- is the measurement of a real or imaginary line extending from one point to another. Volume- the space an object occupies. Meniscus- Mass- the quantity of matter in a given object.
