Scientific method

Scientific method

1. Science is an ordered body of objective knowledge which can be verified experimentally.

2. Steps

   • 1 Observation
   • 2 Search for information
   • 3 Statement of hypothesis
     • A hypothesis is a supposition which attempts to explain an observed phenomenon.
   • 4 Experimentation
   • 5 Analysis of results
     • Data table
     • Pie chart.
     • Bar chart.
     • Graph or representation on coordinate axes.
   • 6 Formulation of laws
     • Qualitative law
       • t can be defined through a verbal or written statement, but cannot be expressed numerically.
     • Quantitative law:
       • it can be expressed through numbers. Thus, in addition to being defined through a verbal or written statement, it can be represented as a mathematical formula and as a graph.
   • 7 Theories and models
     • A theory is a generalised law which explains a set of facts.
     • A model is a graphical or mental representation which helps us to interpret how something is.
   • 8 The scientific report
     • Cover
     • Table of contents
     • Summary or abstract
     • Purpose
     • Materials and products
     • Procedure
     • Results and conclusions

3. The scientific method is the method of working based on observation and experimentation, which scientists use to investigate the phenomena produced in nature.
