1. The investigatory process Ways of acquiring knowledge and solving problems

2. Ways of Acquiring Knowledge and Solving Problems At the end of the lesson, Jamenians should be able to: Describe what is meant by fair test ; and Identify the components of investigation Conduct simple investigations that use processes involving mixtures common to the locality.

3. Guide Questions H ave you ever wondered why the sky is blue? W hy plant leaves have different colors? Have you ever asked why ice melts? Have you ever thought why people look different from one another?

4. Guide Questions Have you ever been curious to know how scientists discovered and applied these scientific concepts? What are they thinking before they arrived at a particular scientific principle? Did they follow a specific process?

5. Scientific method Scientists use the systematic way of solving a problem. This is not stepwise list of procedures but a flexible, scientific, and creative way of addressing a particular problem or objective.

6. Steps to follow: Identify the problem Gathering preliminary information Formulating the hypothesis Conducting the experiment(s) Making generalization/conclusion Reporting the research

7. Identifying the problem In choosing a research topic, some important points you need to consider include the availability of materials, the relevance of the topic the socio-economic needs of your community or country, and clearly defined goals to help you make a definite conclusion later on.

8. Gathering preliminary information This step can be done by reading write-ups, articles, projects or finished researches closely related to your topic.

9. Formulating the hypothesis An educated guess or inference to explain the observed facts. After the experimentation is completed, the hypothesis can be tested and verified.

10. Conducting the experiment/s An experiment is a clear set of detailed procedure and materials that tests your hypothesis. The factor that being tested is called the single variable factor. you can conduct a fair test making sure that y ou change one factor at a time while keeping other factors constant. Quantitative or qualitative

11. Making generalization/conclusion A statement that answers the objectives of the research. One of the important characteristic of it is its validity. A hypothesis may become a theory if an experimental datum continues to support the hypothesis.

12. Reporting the research Sharing the results of research through magazines, journals, published papers, and conference are ways of reporting a research.

13. The scientific method is not a strict sequence of steps but a systematic way of answering a problem or explaining and predicting a specific phenomenon. What everyday situation can you give wherein you use the scientific method or thinking?

14. Scientific Attitudes A person’s outlook on how he/she conceives or understands situations or events.

15. Scientific Attitudes Intellectual honesty Openness to new ideas and information Curiosity about natural phenomena and technological advances Tolerance of other views Persistence and love for work Willingness to be convinced by evidence Recognition of the tentativeness of scientific findings

16. Scientific Attitudes Awareness of the limitations of science Respect for life Cooperation in working with others Appreciation of the unity, order and beauty of nature Objectivity in discussing controversial issues Ability to suspend judgement until all necessary evidences are available Resourcefulness and the like

17. Steps to follow: Making generalization/conclusion Formulating the hypothesis Reporting the research Identify the problem Conducting the experiment(s) Gathering preliminary information

18. TRUE OR FALSE 7. The scientific method is not a strict sequence of steps but a systematic way of answering a problem . 8. Scientists use scientific method as the systematic way of solving a problem. Reporting the research is an educated guess or inference. 10. Making generalization is a step that can be done by reading write-ups, articles, projects or finished researches closely related to your topic.
