Document Summary
Observation is the act of viewing the world around us. Experimentation is a disciplined and controlled way of asking and answering questions about the world in an unbiased way. Hypotheses are tentative explanations for questions raised by observation. Observations and experiments do not prove hypotheses, they can only support or reject them. Controlled experiments are a powerful type of test in which several groups are tested with the same protocol and conditions. These include the manipulation of a variable by adding an independent variable and running a test group that attempts to find the importance and effects of the variable on what is being tested. There is also a controlled group to determine the baseline without manipulating experiments. Scientific method is a deliberate and careful way of asking questions about the unknown. Theories are general explanations of the world supported by many observations and experiments (such as evolution and gravity)
