The Scientific Method 1. Choose a problem. (What do you want to explore? Ask a question about it.) * Choose something that interests you. * Choose something that you don’t know the answer to. * Choose something you can work with. Which soda decays fallen out teeth the most? 2. Research the problem. (How can you find the answer to your question?) * Look in books. * Get advice. * Make observations. If you take your teeth‚ put them in a glass‚ pour soda over them and let them stand

Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

THEORETICAL FRAMEWORK A theoretical framework is a conceptual model of how one theorizes or makes logical sense of the relationship among the several factors that have been identified as important to the research problem concerned. To put it simply a theoretical framework involves identifying the network of relationship among the variables considered important to the study .It provides the conceptual foundation to proceed further with the research. The theory is developed based on the documentation

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Bacterial Contamination April 15‚ 2013 Bacteria Contamination The definition of bacterial contamination is food contamination refers to foods that are spoiled or tainted because they either contain microorganisms‚ such as bacteria or parasites‚ or toxic substances that make them unfit for consumption This is very serious and people should take more precaution‚ food contamination is a serious because it results in foodborne diseases that each year affect an estimated seventy-six million

to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter and a rotameter respectively. The head losses in each meter will be calculated and compared with each other alongside those arising in

Advantages of the use of the scientific method in psychology There are a number of advantages to using scientific methods in psychology. Firstly an important aspect of imperial data is that it is objective‚ i.e. not affected by expectations of the research. So‚ without objectivity we have no way of being certain that data collected is valid. An example of this is seen with Gardner & Gardner. When they observed Washoe they might have judged that Washoe was using real words because they wanted

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze
