The steps of Scientific-Method-WEEK-1.pptx

The scientific method is an empirical method for acquiring knowledge that has characterized the development of science. The scientific method involves careful observation coupled with rigorous skepticism, because cognitive assumptions can distort the interpretation of the observation. the study of the scientific method is the attempt to discern the activities by which that success is achieved. Science is an enormously successful human enterprise. The study of scientific method is the attempt to discern the activities by which that success is achieved. Among the activities often identified as characteristic of science are systematic observation and experimentation, inductive and deductive reasoning, and the formation and testing of hypotheses and theories. How these are carried out in detail can vary greatly, but characteristics like these have been looked to as a way of demarcating scientific activity from non-science, where only enterprises which employ some canonical form of scientific method or methods should be considered science (see also the entry on science and pseudo-science). Others have questioned whether there is anything like a fixed toolkit of methods which is common across science and only science. Some reject privileging one view of method as part of rejecting broader views about the nature of science, such as naturalism (Dupré 2004); some reject any restriction in principle (pluralism).

Scientific methods should be distinguished from the aims and products of science, such as knowledge, predictions, or control. Methods are how those goals are achieved.

9. SCIENTIFIC METHOD

10. SCIENTIFIC METHOD The scientific method is a process for experimentation that is used to explore observations and answer questions. 

11. 1. Identifying the Problem 2. Gathering Data 3. Formulating hypothesis 4. Doing an experiment 5. Making conclusion 6. Application STEPS IN SCIENTIFIC METHOD PDHECA

12. 1. IDENTIFYING THE PROBLEM A problem can be identified after a thorough observation or relying on existing data. In observing we have to use our 5 senses to gain information. After observation comes a question, which is now your statement of the problem. A good scientist will ask lots of questions

13. Making an Observation SENSES

14. Making an Observation OBSERVATION: the tomato plant that is placed in an area with sunlight has a lot of fruits. On the other hand, the tomato plant that is placed on a shaded area has lesser fruits.

15. Asking a Question A problem is a question that you want to solve or the things you want to discover. Question/Problem: Why the tomato planted located where there is sunlight have more fruits than the tomato plant located on a place where there is little amount of sunlight?

16. 2. G ATHERING DATA Gathering of data in a form of research, interview or existing data. Evidence is needed to test the prediction. There are several strategies for collecting evidence, or data. Scientists can gather their data by observing the natural world, performing an experiment in a laboratory, or by running a model. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data.

17. 3. FORMULATING A HYPOTHESIS (scientific guess/ educated guess) A hypothesis is a possible answer to a question. It is based on: their own observations, existing theories, and information they gather from other sources. Scientists use their hypothesis to make a prediction, a testable statement that describes what they think the outcome of an investigation will be.

18. FORMULATING A HYPOTHESIS HYPOTHESIS: If potato placed in an area where there is enough sunlight, then it will produce more fruits.

19. 4. DOING AN EXPERIMENT Testing the hypothesis. Scientists organize their data in tables, graphs, or diagrams. If possible, they include relevant data from other sources. They look for patterns that show connections between important variables in the hypothesis they are testing.

20. 4. DOING AN EXPERIMENT 3 kinds of variables: a. Manipulated variables or independent variable b. Responding or dependent variable c. Controlled variable

21. 4. DOING AN EXPERIMENT a. Manipulated variables or independent variable - is a factor or condition that is intentionally changed by an investigator in an experiment. An independent variable is the cause . Its value is independent of other variables in your study. 3 kinds of variables:

22. 4. DOING AN EXPERIMENT b. Responding or dependent variable - is a factor or condition that might be affected as a result of that change . A dependent variable is the effect . Its value depends on changes in the independent variable. 3 kinds of variables:

23. 4. DOING AN EXPERIMENT c. Controlled variable - A variable that is not changed is called a controlled variable . These factors are kept constant to determine any changes in the results (dependent variable) is caused by the manipulated variable. 3 kinds of variables:

24. DOING AN EXPERIMENT HYPOTHESIS: If potato placed in an area where there is enough sunlight, then it will produce more fruits. Manipulated or Independent : (cause) amount of sunlight Responding or dependent : (effect) number of fruits that a tomato plant will produced Controlled : (constant) amount of water, type of soil, type of plant, and the size of the pot 3 kinds of variables:

25. 5. MAKING CONCLUSION Make a statement that accept or reject the hypothesis. The scientist will report his or her findings so that others may know what they find out. Based on whether or not their prediction came true, scientists can then decide whether the evidence clearly supports or does not support the hypothesis. If the results are not clear, they must rethink their procedure. If the results are clear, scientists write up their findings and results to share with others. The conclusions they draw usually lead to new questions to pursue. This will give you an answer if your hypothesis is correct or not.

26. MAKING CONCLUSION CONCLUSION: Plants such as tomato plants that are placed in an area with enough amount of sunlight produced more fruits than those plants placed in less amount of sunlight . HYPOTHESIS : If tomato plant is placed in an area where there is enough sunlight, then it will produced more fruits .

27. 6. APPLICATION Putting something into use/operation based from the outcome of the experiment. . Publishing on scientific journals, presenting using a poster, or presenting at a conference. Informing others about the results of the experiment.

28. SCIENTIFIC METHOD PDHECA

29. My wallet is missing. How could I use the scientific method to solve this problem ? SAMPLE PROBLEM

30. 1. Identifying the P roblem :  Missing Wallet 2. Gathering Data :  I went to the market to buy some goods with my friend Princess . When I reached home I noticed that my wallet was gone. 

31. 3. Formulating Hypothesis: My first hypothesis was: I lost it in the market while we were buying goods. The second hypothesis was: Princess got my wallet. The third was: I had misplaced it in the house.

32. 4. Doing an experiment:  I searched all over the house for my wallet, but I could not find it. Then I went to Princess to ask  If she got my wallet. She answered in the affirmative . She said she found it while she was on her way home near the market.

33. 5. Making Conclusion:   I lost my wallet in the market and Mae Ann found it and gave it back to me.

34. 6. Application: tell friends to keep valuables and prevent this from happening again.
