ask well-defined questions, formulate testable hypotheses, and select and use appropriate equipment and technology;
collect information by detailed observations and accurate measuring;
analyze and interpret information to construct reasonable explanations from direct (observable) and indirect (inferred) evidence;
demonstrate that repeated investigations may increase the reliability of results;
