UNIT 1 THE SCIENCE OF CHEMISTRY / 1.4 SCIENTIFIC MEASUREMENT 1.4 Investigation: Scientific Measurement … • It is important for researchers and also consumers of research to understand statistics so that they can be informed, evaluate the credibility and usefulness of information, and make appropriate decisions. A measure of the average kinetic energy (amount of motion) of particles that make up matter. While we look at these various categories as stoic forms of mathematical measurements a closer examination of things we do in everyday life reveals their clear importance. Some common tools used in experiments are a timer, thermometer, scale, telescope, measuring container, light source, water, pencil, note book and tape measure. Explain why valid experimental results must be based on standards. Prove to be false, or not support (in reference to a hypothesis.). According to Maxim (1999), measurement is a process of mapping empirical phenomena with using system of numbers. Data that is gathered in the form of numerical measurements. STUPYX: Scale, Title, Units (on the DV), Plot, Y axis (with the DV), X axis (with the IV). STUDY. It is most often measured by the liter (L), 1.057 qt. A statement in an investigation that gives the reader information about the details of the investigation. The standard metric unit for measuring length or distance. The steps used in a scientific investigation may also vary. Nominal scientific measurements are numbers arbitrarily assigned to variables, allowing easier manipulation of sets.For example, a researcher with 6 sample groups might prefer to refer to them as numbers. A scientific investigation typically begins with observations. For example, if a teacher wants to know how much algebra her students learned during the se… The scientific method is a technique primarily used in science to orderly and rationally performs procedures to obtain a result or conclusion. Once again it may have worked out just fine, but other times it turns into a disaster. The scientific method is important in scientific investigation because it helps to test predictions (hypotheses). The variable in an investigation that may change in response to changes in the independent variable. Taking the hypothesis into consideration, about a dog and a stranger, this would involve a dog, someone who is a stranger to the dog, and someone familiar with the dog. At this final stage, your hypothesis may be proven correct or incorrect. Measurement is part of our daily life. A logical interpretation based on prior knowledge and experience. A typical question could be: “What causes a dog to bark?” Equipping yourself with knowledge on the subject area, and looking at similar investigations on the topic will prove useful.

Why Measurement Is So Important. It is important for scientific research to occur at a local level because research from one area may not be applicable to … •Test them using the scientific method: –Choose a question to be answered. The hypothesis is extremely important because it bridges the gap between the realm of ideas and the real world. At this stage of the investigation you will execute your experiment and record your data. Michael Echols December 6, 2010. The standard metric unit for measuring mass. in conventional units, or the milliliter (mL), 1/1000 of a liter, about 0.0338 of an ounce. Even the most careful and rigorous scientific investigation (or any type of investigation for that matter) ... an important indication of confidence within a measurement is the number of significant figures reported. Accurate measurements are important because precise amounts are required for reactions to take place, for a recipe to turn out and to keep correct records of a measurement. Using weather as an example, this module takes readers through the steps of data collection, analysis, interpretation, and evaluation. How one differentiates between cm, inch, foot, meter, mile and km. To ensure an accurate result you may use more persons in the investigation to prove your hypothesis. Measurement plays an important role, and when possible the scientist attempts to test his theories by carefully designed and controlled experiments that will yield quantitative rather than qualitative results. • Statics is very important when it comes to the conclusion of the research. In an experiment, the level of IV that is used for comparison. A diagram that shows how two variables are related. You will provide details of your outcome, and give reasons for this result. They make observations by gathering information with their senses. –Use the data yielded by the method to draw a conclusion regarding the hypothesis. It is important that the tools used are in proper working condition to ensure accuracy in your results. Example, you may look at another hypothesis in relation to the dog and what causes a dog to bark, which may be: “A dog barks when provoked.” This is performed by repeating the five steps in the investigation process. If you are not very satisfied or still unsure with your result you may repeat the experiment. Repeats are done if you wish to obtain an average. Unless one needs to reinvent the wheel, precise awareness on the extent of knowledge on a topic is important to hold on analysis that adds worth to the sphere. The answer you have arrived at will become your hypothesis for this investigation, which will be tested by an experiment or simple observation. Why is scientific method important? Anything that takes up space and has mass. A property of matter that is observed during a chemical reaction. why are standard units of measurements important in scientific experiments or laboratory investigations? In the book Research Methods for the Behavioural Sciences reliability is defined as a measurement procedure that has stable results or the consistency of the measurement. Why Measurement Uncertainty is Important. Physical Property. When measurements are not accurate, this provides incorrect data that can lead to wrong or even dangerous conclusions or results. Prefix meaning 100 whole units of something (such as meter, liter, or gram). Your data needs to be representative of the target study population.

Volume, as measured in chemistry, is the amount of space that matter occupies. October 3, 2012 by Richard Hogan. and why do you have to do it? This will make the discussion of the methods and results less difficult.For example,The numbering system merely provides a point of reference, and no underlying relationship or structure is inferred. So why is reliability important? This applied science allows individuals, industries and countries to test information by transforming abstract theories into practical learning. The metric system is in place as a standard unit of measurement. The accuracy of these measurements is determinate upon an established set of requirements. Measure aims to ascertain the dimension, quantity, or capacity of the behaviors or events that researchers want to explore. This investigation will possibly provide new knowledge or discoveries, correct a previous finding, or further enhance an earlier experiment. In the planning stage of your investigation you decide on all the different requirements or apparatus needed to perform your experiment or observation, and exactly how you will proceed. The measurements might be made in a controlled setting, such as a laboratory, or made on more or less inaccessible or unmanipulatable objects such as stars or human populations. Based on the situation presented there is something to find out, which may either be what, how, when, where or why. A value or condition in an experiment that does not change. The specific items of the independent variable that will be tested separately. Quantitative measurements are performed each day. Instrument used to measure the m ass of an object. and what will it show and improve? Qualitative Data. Data analysis is at the heart of any scientific investigation. Measurement addresses a fundamental question that arises in many scientific studies (and everyday activities): "How big or small is it?" Data that is gathered in the form of numerical measurements. A scientific investigation is a process involving five steps, which are designed to confirm an idea or opinion put forward based on a question to be answered. (Note it is more precise than a beaker). Answering this question can involve either direct or indirect measurements. A measure of a distance between two points. To be as accurate as possible, with certain investigations you may have to do repeat trials. Data in the form of descriptions gathered from the 5 senses. When it comes to scientific investigations we need to be precise because just as with playing games and following recipes it could cause something to be dra… The scientific method is important because it is an evidence-based method for acquiring knowledge. The experimental factor (variable) that is purposefully changed by the investigator. To form hypothesis without definite knowledge or evidence. This scientific investigation can be expanded by exploring related areas of this topic. For example, determining the size of a television screen can be done directly by using a tape measure. The module explores how scientists collect and record data, find patterns in data, explain those patterns, and share their research with the larger scientific community. An instrument used to measure the volume of liquids or objects. Many other measurements, including most of those done by scientists, must be done indirectly.
