Fair+Test


 * Fair Test**

A fair test is an investigation carried out under strictly controlled conditions to test a theory and to ensure accuracy and reliability of results. In a fair test, all variables are identified and controlled except the one under investigation. A fair test requires an effective method of reporting and communicating the results of tests. A fair test is used in science and technology investigations and inquiries when active exploration and hands-on investigation will best promote learning to apply theories and concepts. It follows the scientific method of asking a question, making a hypothesis, setting up appropriate test conditions, conducting the test, making observations, drawing conclusions, and repeating the cycle. Fair tests should be able to be replicated by others with the same results. Fair tests can be conducted using computer software that simulates real conditions.
 * Description**

The teacher:
 * Method**
 * selects which investigations are suited to fair tests;
 * makes equipment and materials available to support the design of fair tests;
 * instructs students in identifying and controlling variables;
 * encourages students to question and design their own fair tests;
 * helps students to identify how to connect learning to real-life situations;
 * ensures the development of specialized vocabulary required in conducting fair tests.

Fair tests:
 * Considerations**
 * should encourage students to record relevant data collected from conducting fair tests, by using charts, tables, graphs, and computer-assisted applications such as spreadsheets;
 * involve ensuring proper safety equipment and procedures are in place.
