Why might a scientist choose to do a case study instead of a controlled, lab experiment?
Anyone can do a case study where you must have a college degree in science
Case studies are always more accurate that other methods of experiments
case studies are conducted rare case where large samples of similar partici
Case Study results can always be generalized to be the wider population

observation
inference
3
Which statement does NOT describe a scientific theory?
A scientific theory can never be proven
A scientific theory is supported by facts

What would be a testable question Sally could ask about the cardinals' feeding habits?
Why do cardinals like one kind of seed more than others?
