A Possession of knowledge as disHnguished from ignorance or misunderstanding; B Knowledge a3ained through study and pracHce C Knowledge covering general truths or the operaHon of general laws especially as obtained and tested through the scienHfic method D ScienHfic Method Principles and procedures for the systema'c pursuit of knowledge involving the recogni'on and formula'on of a problem, the collec'on of data through observa'on and experiment, and the formula'on and tes'ng of hypotheses. 8/25/11 GG303 14 7 8/25/11 ScienHfic Method 8/25/11 GG303 15 1.
