- 27. What is a fair Test? Conducting a fair test is one of the best practices of experimental research because it helps prove that the outcome is attributed only to the manipulative variables. Prepared by: D. C. Tabinga, Jr.
- 28. The Dependent and the Independent Prepared by: D. C. Tabinga, Jr. Variable • Variables- The factor that can be changed in the experiment. • Experimental Variables-is allowed to change in order to determine the effect. • Dependent Variable-are the variables allow changes in amount, treatments, or any applications. • Independent Variable -are not subject to change.
- 29. Prepared by: D. C. Tabinga, Jr. Isolation • Isolation The scientist separates the material being studied from everything else • Control – in any study, the part of the experiment or test that provides a standard of comparison with which to confirm or rule out errors in the experiment. • Controlled Experiment- where the researchers isolate and test the effect of the variable. • Data-information gathered

- Teacher Reading/ Activity ________________________________________ Student Reading/Activity ________________________________________ About the Slide ________________________________________ Other Information
- Scientists frequently follow a similar approach or procedure in investigating nature. They make observations, draw conclusions from them, perform experiments, test and retest until an acceptable explanation is arrived at. The following is a more detailed explanation of each steps in a scientific investigation.
- To observe means to investigate the object being studied. This includes looking at it, touching it, smelling it, or listening to it. To become more meaningful, observations should be classified. When you classify, you are grouping the data so that all the members of the group have least one characteristic in common. If the pattern of consistency is found in all observations, a verbal or mathematical statement, which relates a series of observations that have been verified again and again, is formulated. This statement is called a scientific law. The law merely summarized what has been observed.
- A problem refers to a query regarding observation. All normal young children are naturally inquisitive, but inquisitiveness in an adult distinguishes the scientist from the layman. Everybody makes observations but only a few show further curiosity. The growth of scientific knowledge is dependent on the skill of a scientist in asking important questions – questions that the application of current knowledge and technology can answer.
- It is an educated guess explaining an observation. A hypothesis refers to a tentative model. A scientific model is a picture or representation of that which we cannot see but whose existence would explain some experimental observations. It is only imagined.
- A given question may have a thousand possible answers but only one right answer. One will not know whether a guess is correct or not until one has experimented on it. Experimentation is a very important component of science. There are no rules to follow; each experiment in a case unto itself.
- A theory always remain tentative] Meaning of Theory: A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena. The branch of a science or art consisting of its explanatory statements, accepted principles, and methods of analysis, as opposed to practice: a fine musician who had never studied theory. A set of theorems that constitute a systematic view of a branch of mathematics. Abstract reasoning; speculation: a decision based on experience rather than theory. A belief or principle that guides action or assists comprehension or judgment: staked out the house on the theory that criminals usually return to the scene of the crime. An assumption based on limited information or knowledge; a conjecture. Meaning of Law: A general principle or rule that is assumed or that has been proven to hold between expressions.
- SCIENTIFIC PROCESS SKILLS According to American Association for the Advancement of Science, the basic science skills include (a) observing, (b) classifying, (c) measuring, (d) inferring, (e) predicting, (f) communicating, and (g) using number relationships. Integrated science process skills include (a) formulating hypothesis, (b) identifying and controlling variables, (c)defining operationally, (d) designing investigation/experimenting, and (e) formulating models. Scientists investigating phenomena in nature make discoveries and findings. These become products of science. Scientific products may be concepts, principles, generalizations, theories or laws.
- Explain the concept of the following myth.
- Explain the following modern concept. 1.The world is spherical in shape. 2. It was discovered by Copernicus that the center of the Solar System is the Sun. It was supported by the studies of Galileo Galilee 3. A Living dragon is known as the Comodo dragon. It is a reptile that emit gases that can produce fire. 4. According the theory of evolution of Charles Darwin ---- Man came from apes. Like any organism in the planet we are also a product of evolution. The teacher is encourage to site more significant scientific theories.
