1.4 How science works
Science investigation and research requires many skills and processes to come together in
order to be successful and worthwhile.- To be accepted as a science, certain methods for broadening existing knowledge, or
discovering new things, are generally used. - These methods must be repeatable and follow a logical approach.
- The methods include formulating hypotheses and carrying out investigations and ex-
periments to test the hypothesis. - Crucial skills are making objective observations, taking measurements, collecting in-
formation and presenting the results in the form of drawings, written explanations,
tables and graphs. - A scientist must learn to identify patterns and relationships in data.
- It is very important to then communicate these findings to the public in the form of
scientific publications, at conferences, in articles or TV or radio programmes.

find the answers to their questions. Using the scientific method there are very few things we6 1.4. How science works
