        1.Careful planning and design
        
        2.Ensuring the experiment is safe
        
        3.Design a control experiment
        
        4.Experiments must be fair
        
        A control is used to provide a comparision against which the actual experiment can be judged
    - - The extent of human knowledge
      - The basis of investigation
        
        If the basis of an investigation is poorly designed or improperly carried out it will not yield results that are as valid as they should be
      - Interpreting results
        
        If results are interpreted wrongly, then faulty conclusions and hypothesis may be drawn. It is important that the results of any experiments are analysed and considered in a proper manner
      - Changes in the natural world
      - Accidental discoveries
