AIOU Solved Assignments 1& 2 Code 837 Spring 2020

Q 1.  Explain briefly each source of knowledge and discuss which source is most important and why?. Science is the study or collection of knowledge in a logical and orderly fashion obtained by observation, interpretation and testing. Scientific Methods include recognizing and solving problems, finding answers to the questions arising out of observations, study and experimentation. These uncover new facts and establish new concepts or hypotheses. Rules, laws or principles are evolved only after the hypotheses are tested and verified. The following steps are involved in the scientific study:

  1. Observation:

Observation is reacting and recognizing the surroundings. Our perception of the world around us is mainly through sight, but we do perceive through smell, hearing, taste and touch. A critical observation is basis of scientific approach as it leads to many queries. Observations may be direct or indirect. For example, magnetic or gravitational forces cannot be observed directly. These can be recognised by their effects. In recent years our perception power has been augmented with scientific tools. Optical instruments like microscopes, telescopes, binoculars have increased our observation ability.

  • Defining a Problem:

It involves recognizing or understanding a problem arising out of observation and to make a clear statement. This leads to asking questions what, when, why and how?

  • To Collect Information relating to the Problems:

Information’s about the problem are collected from scientific records to ascertain what is already known about the problem to be investigated.

  • Formulation of working:

Hypothesis is the proposed solution for a problem, predicted on the basis of all available information’s. It is just a speculation or assumption as yet unproved. It is sometimes called ‘a working hypothesis’ that gives a possible solution to a problem.

  • To test the hypothesis:

The proposed hypothesis is tested trough – Controlled scientific experiments, additional accurate observations and investigations, or by combining the two. It is not always easy to devise a suitable test or a good experiment. An ideal experiment involves –

  • Use of a control
  • Appropriate materials
  • Well defined procedure
  • Careful observation and collection of data
