  1. KEY CONCEPTScience is a way of thinking, questioning, and gathering evidence.

  2. Like all science, biology is a process of inquiry. • Scientists make careful and systematic observations. • Scientists record observations as data. • Scientists form a hypothesis as a possible answer to a     question. • Scientists test their hypotheses and analyze their data.

  3. Biologists use experiments to test hypotheses. • Observational studies allow scientists to describe a phenomenon.

  4. Experimentals allow scientists to determine what causes a phenomenon.

  5. Experimental studies allow scientists to determine what causes a phenomenon. • Independent variables are manipulated. • Dependent variables are observed and measured. • Constants are conditions that are kept the same.

  6. A theory explains a wide range of observations. • Theories explain a wide range of observations and experimental results. • A theory is supported by a wide range of scientific evidence. • Theories can change based on new evidence. New evidence shows that ulcers are caused by bacteria.
