Good work! Now, let’s talk about what you have
                     learned from these activities. Let us explain
                        the concept of Scientific Investigation.




                       A scientific investigation is a plan for asking questions and testing possible
               answers in order to advance scientific knowledge. Investigation is at the heart of
               science. It is how scientists do research.
                       Scientists investigate the world in many ways. In different fields of science,
               researchers may use different methods and be guided by different theories and

               hypotheses. However,  most  scientists,  including  physical  scientists,  usually  follow
               the general approach. This approach is called the Scientific Method and typically
               includes the following steps:
                     Identify a research question or problem. Stating the problem you want to
                  solve or the question you want to answer.

                     Collect information. Gathering information about the problem by observation.
                     Form  a  hypothesis.  Making  a  prediction  about  what  will  happen  with  the
                  experiment. Thinking of a possible answer or solution to the problem.

                     Experiment. Testing the hypothesis if it is correct or not. The things that are
                  changing in an experiment are called variables. A variable is any factor, trait, or
                  condition that can exist in differing amounts or types. An experiment usually has
                  three kinds of variables: independent  (one that is changed), dependent  (result
                  that depends on changes being done), and controlled (things that are remained
                  constant).

                     Record  and  study  data.  Watching,  noticing  and  writing  down  the  events
                  happening during an experiment. Presenting the data in a chart, graph or other
                  visual forms.
                     Draw conclusions. Explaining whether the experiment worked or not.
                    Scientists often undertake the steps of an investigation in a different sequence,
               or they repeat the same steps many times as they gain more information and develop
               new ideas.


                                                   Do you now understand the concept of Scientific
                                                  Investigation? Are you now familiar with the steps
                                                    in Scientific Method? If yes, let’s try another

                                                                          activity.
