Firstly, there is the tendency to reduce scientific practice is minimized to a single set of procedures, such as the identification and control of variables, the classification of persons and the identification of sources of error. The reasoning is also required to issues with, for example, the best experimental design, the most appropriate techniques of data analysis, or the best interpretation of a given data set. On the other hand, many scientific studies, such as the search for the planet’s distant orbiting stars, which are driven by curiosity and carried out with the aim of answering a question about the world or understanding. These sketches are based on the Committee’s judgment, since there is very little scientific evidence as yet on the developmental trajectory of each of these practices. Yet students ‘ opportunities to immerse themselves in this practice, and to explore why they are at the centre of science and technology are important to the appreciation of the competence of the expert and the nature of his or her company. As they progress through the grades, their questions should gain in significance, and demanding. Similarly, should the students gain experience in the application of computer programs to transform their data between various tabular and graphical forms to aid in the identification of patterns. To communicate the science can advance is not easy, if the scientists are able to see their results clearly and convincingly.. In an early design stage, competing ideas must be compared (and possibly combined) to a first design, and the decisions by reasoning about the merits of different ideas, the objectives relevant for the design. These investigations can be enriched and extended by linking to engineering design projects—for example, how students can apply what they have learned about ramps to design a track that makes a ball go a certain distance, a loop, or hold on hard pistes
The dominant activities in this area, the reasoning and the criticism, which often lead to further experiments and observations or to changes in proposed models, explanations, or designs. They also need experiences that help them to recognize that the laboratory behavior is not the sole domain for legitimate scientific research, and that for many scientists (e.g., earth scientists, researchers, ecologists), the \\\”lab\\\” is the natural world where experiments are conducted and data collected in the field. To read as the students begin and write more texts, the particular genres of scientific text—a report of an investigation, a statement introduced with the support of argumentation, an experimental procedure, and their purpose explored..
Other types of engineering problems also benefit from special computer-based simulations in the design and test phases.
They also provide powerful new techniques for the mathematics to model complex phenomena—for example, the circulation of carbon dioxide in the atmosphere and in the ocean.
Scientists use deductive reasoning, but also the search for patterns, classify objects, make generalizations from repeated observations, and engage in a process of making inferences on what might be the best explanation.
For people, the questions do not natural scientists or engineers, the ability to well-defined questions is an important part of science literacy, helping to make them critical consumers of scientific knowledge.
In addition, information technology is the acquisition of data beyond the classroom at all hours of the day.

Shouse (Eds.). Used in science and engineering as either structural, functional, behavioral, or analogs, albeit simplified, conceptual models, diagrams, physical replicas, mathematical representations, analogies, and computer simulations. A. These tools and strategies allow it to capture scientists and engineers and to analyze large amounts of data, search for distinctive patterns and identify relationships and important characteristics in a manner previously impossible. In this area of activity, which determine a scientist, what needs to be measured; observe phenomena, plan experiments, programs of observation and methods of data collection; build instruments; engage in disciplined fieldwork; and the sources of uncertainty. A. This is an essential step in the construction of their own understanding of the phenomena to a greater appreciation of the significance of the scientific theories they learn in the classroom and in the acquisition of deeper insight into how scientists work. R. Duschl, H. W. Increasingly, scientists are required to engage in dialogues with lay audiences about their work, which requires especially good communication skills. Although their role is often misunderstood—the informal use of the word \\\”theory\\\”, after all, can mean a guess— scientific theories are constructs based on significant bodies of knowledge and findings will be revised in the light of the new findings, and must endure, substantial control by the scientific community before you widely accepted and applied. For engineering, you should ask questions in order to define the problem to be solved and to elicit ideas that lead to, the restrictions and / or specifications for the solution. Historical case studies of the emergence and development of a scientific idea show how a new idea is often difficult to accept and to argue—archetypal examples are the Copernican are a niche idea that the earth revolves around the sun and Darwin’s ideas on the origin of species. A scientific hypothesis is neither a scientific theory nor a guess; it is a plausible explanation for a phenomenon, you can predict what will happen in a given situation. Board on Science Education, center for education. Modern computer-based visualization tools often allow data to, the various forms are displayed and thus engage the learner interactively with data in their analyses. Schweingruber, and A. The overarching goal is for all high school graduates are expected to contribute sufficient knowledge of science and technology in public discussions on science topics, the caution of the consumers of scientific and technical information, and enter the career of your choice.. Committee on science Learning, Kindergarten through Eighth grade. For example, a structural engineer mathematical models of bridge and building structures based on physical laws, to test their performance, probe their structural limits, and to assess whether they can be completed within acceptable budgets. With data in hand, you can analyze the engineering to how well the various solutions meet the specifications and constraints and then evaluate what is necessary to the leading design is to improve or develop a better one. The students should be helped to recognize that they need to explore more, as a way to your data in order to identify and present important functions
