Biol 101 10 January 2008 Biology o Scientific study of life o Foundation for questions about life and the natural world Scientific Method o Gathering new information starts with observation – have to be the type that one can speak clearly about – objective, not subjective observation o Making sense of observations is done by making a hypothesis (prediction is generic, hypothesis is fairly carefully stated) Can state in an “If/Then” form (If I eat breakfast, then I will stay awake) Independent and dependent variables (eat at different times, eat different foods) New hypothesis “The timing of breakfast/what I eat for breakfast…” o You know whether a hypothesis is good based on how hard it is to come up with an experiment Characteristics of a good experiment Single variable (hold other factors constant) – same type & time, same way to test awake (yes/no) Control (unmanipulated variable) – people who don’t eat breakfast Multiple results (many individuals and/or many trials)
