Chem+Friday,+August+29,+2008

=Chem: Friday, August 29, 2008= Today we reviewed the Scientific Method (see notes below). Then, we watched the "Helium Football" episode of //Mythbusters// and identified the different components of the Scientific Method demonstrated in the episode.
 * Make an observation (using your senses)
 * The observation usually results in a Question
 * Develop a hypothesis (educated guess)
 * Test the hypothesis with an experiment
 * Controlled Experiment
 * Control Group - no experimental conditions are changed
 * Experimental Group - only one experimental condition is changed
 * Independent Variable - the variable that we change
 * Dependent Variable - the result of the change in the independent variable
 * Gather Data
 * Analyze Data
 * Draw a conclusion (Does it support the hypothesis?)
