  3. It helps us to gain new knowledge

iii. It helps us to conduct project work

iv.It helps us to carry out field study

  (b) Scientific procedure applied in:-

     (i) Carry out experiments.

            For studying and gaining new knowledge through testing.

   (ii) Project work.

             To plan by studying the project or problem so as to find useful information or solution for the project.

    (iii) Field study.

              To find answers for the problem by doing practical work.

  1. (i) scientific procedure is a set of techniques used by scientists to investigate a problem/answer question.

   (ii) Hypothesis is an answer to the problem that may be true or false.

   (iii) Experimentation is practical activity aiming to get the solution of the problem.

   (iv) Observation is the process of detecting results of the experiment.

   (v) Variables are factors that affect the problem when conducting an experiment.
