The scientific method is a process for experimentation that is used to explore observations and answer questions. Even though we show the scientific method as a series of steps, keep in mind that new information or thinking might cause a scientist to back up and repeat steps at any point during the process. Whether you are doing a science fair project, a classroom science activity, independent research, or any other hands-on science inquiry understanding the steps of the scientific method will help you focus your scientific question and work through your observations and data to answer the question as well as possible.

What is the Correlation of Science with other Subjects? Correlation of Science with other Subjects As known that for over all development of the students, various subjects are being included in the curriculum. These subjects are not selected on ad-hoc basis, but this decision is taken after proper consideration and analysation. Generally those subjects are included in the curriculum which is found to be complementary to each other, as the main objective of all of them is to achieve set objective of education that is to bring about over all development of the students. Science is quite a complex and vast kind of subject, because of which the task of correlating it with other subjects of curriculum seems to be quite an easy task. Deliberate effort should be done by the science teacher to bring about co-relation in between the science and other subjects of the curriculum, which are being imparted to the students. Science and Language: To co-relate science with language subjects, students can be asked to write essays on some scientific topic.

Introduction to the Scientific Method Introduction to the Scientific Method The scientific method is the process by which scientists, collectively and over time, endeavor to construct an accurate (that is, reliable, consistent and non-arbitrary) representation of the world. Recognizing that personal and cultural beliefs influence both our perceptions and our interpretations of natural phenomena, we aim through the use of standard procedures and criteria to minimize those influences when developing a theory. As a famous scientist once said, "Smart people (like smart lawyers) can come up with very good explanations for mistaken points of view." I. 1. 2. 3. 4. If the experiments bear out the hypothesis it may come to be regarded as a theory or law of nature (more on the concepts of hypothesis, model, theory and law below). II. As just stated, experimental tests may lead either to the confirmation of the hypothesis, or to the ruling out of the hypothesis. Error in experiments have several sources. III. IV. V. VI. VII. 1. 2. 3.

The Great Question Press Why should teachers nurture potent questioning skills and behaviors? As a practical matter, students need to be able to read between the lines, infer meaning, draw conclusions from disparate clues and avoid the traps of presumptive intelligence, bias and predisposition. They need these thinking skills to score well on increasingly tough school tests, but more importantly, they need these skills to score well on the increasingly baffling tests of life . . . how to vote? how to work? how to love? Drill and practice combined with highly scripted lessons stressing patterns and prescriptions amount to mental robbery - setting low standards for disadvantaged students so they end up incapable of thought or success on demanding tests. This approach contributes to high dropout and attrition rates - early school departures and millions of children left behind.

Science » Explore the 5 E’s of Science Engage These lessons mentally engage the students with an event or question. Engagement activities help students to make connections with what they know and can do. What the Teacher Does Creates interestGenerates curiosityRaises questionsElicits responses that uncover what the students know or think about the concept/topic What the Student Does Asks questions, such as Why did this happen?

Global Connections . Science and Technology Cellular phones, for example, are increasingly popular in the Middle East, providing telephone access in more remote communities as well as in crowded urban areas. Wireless service bypasses the difficult and expensive requirements for laying out and maintaining telephone cables. Satellite television news stations like Al-Jazeera provide new and varied sources of information to people in the Middle East who once had access only to government-controlled media. Internet cafes have sprung up in major cities and in regional centers throughout the Middle East, providing access to news and information for people who cannot afford to buy a computer themselves. Oil-poor countries do not have the economic resources to take advantage of these new technologies.

Interactive Practice on Physical vs. Chemical Properties Review of Chemical vs. Physical Properties and Changes Chemical vs. Chemical properties are properties of an element or compound in chemical reactions. Physical properties are properties of an element or compound that can be observed without a chemical reaction of the substance. Chemical vs. In a physical change , the substances are not altered chemically, but merely changed to another phase (i.e. gas, liquid, solid) or separated or combined. In a chemical change , the substances are altered chemically and display different physical and chemical properties after the change. Practice on Identifying Chemical and Physical Properties Water boils at 100 degrees Celcius. Diamonds are capable of cutting glass. Practice on Identifying Chemical and Physical Changes Dry ice, solid carbon dioxide, is sublimed at room temperature. Salt is dissolved in water. Identifying Different types of Matter.

Questioning Toolkit Essential Questions These are questions which touch our hearts and souls. They are central to our lives. They help to define what it means to be human. Most important thought during our lives will center on such essential questions. What does it mean to be a good friend? If we were to draw a cluster diagram of the Questioning Toolkit, Essential Questions would be at the center of all the other types of questions. All the other questions and questioning skills serve the purpose of "casting light upon" or illuminating Essential Questions. Most Essential Questions are interdisciplinary in nature. Essential Questions probe the deepest issues confronting us . . . complex and baffling matters which elude simple answers: Life - Death - Marriage - Identity - Purpose - Betrayal - Honor - Integrity - Courage - Temptation - Faith - Leadership - Addiction - Invention - Inspiration. Essential Questions are at the heart of the search for Truth. Essential Questions offer the organizing focus for a unit.

History of science "New science" redirects here. For the treatise about history, see The New Science. The history of science is the study of the development of science and scientific knowledge, including both the natural sciences and social sciences. (The history of the arts and humanities is termed as the history of scholarship.) Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real world phenomena. Historiography of science, in contrast, often draws on the historical methods of both intellectual history and social history. Early cultures[edit] In prehistoric times, advice and knowledge was passed from generation to generation in an oral tradition. The development of writing enabled knowledge to be stored and communicated across generations with much greater fidelity.

Teaching Science and Technology in the Context of Societal and Personal Issues Introduction From health to climate change and from bioethics to energy, a myriad of personal and societal issues requires citizens to make informed decisions based on science and technology. These issues provide a rich and motivating context in which students can learn the principles and practices of science and technology. Science and technology influence every aspect of our lives, and in turn, we influence the direction and use of scientific and technological endeavors (Roberts 2007). In addition, science and technology are central to our well-being and success as individuals, as members of society, and as members of the global community. Therefore, NSTA advocates that K–16 science and technology instruction be provided within the context of personal and societal issues. NSTA strongly promotes the education of a citizenry that is scientifically and technologically literate as defined in the National Science Education Standards (NRC 1996). Declarations References DeBoer, G. Roberts, D.

Chemical & Physical Changes Chemical and physical changes are related to chemical and physical properties. Chemical Changes Chemical changes take place on the molecular level. A chemical change produces a new substance. Examples of chemical changes include combustion (burning), cooking an egg, rusting of an iron pan, and mixing hydrochloric acid and sodium hydroxide to make salt and water. Physical Changes Physical changes are concerned with energy and states of matter. How to Tell Chemical & Physical Changes Apart A chemical change makes a substance that wasn't there before.
