Before making a valid conclusion, scientists must A. collect accurate and relevant data B. publish results from the investigation C. communicate the data with other scientists D. consult with other scientists about the investigation
A. Collect accurate and relevant data. This allows scientists to know that their conclusion fits what they tested. All the other steps occur after making a conclusion.

Mark observed the behavior of two golden retrievers. He noticed that whenever he whistled, the golden retrievers started wagging their tails. The golden retrievers stopped wagging their tails when Mark stopped whistling. Mark observed this behavior after 10 trials and concluded that all golden retrievers respond to whistling by wagging their tails. What is the problem with Mark’s conclusion? A. He did not perform enough trials. B. He did not review and summarize his data. C. He did not have a large enough sample size. D. He could not tell if the golden retrievers were responding to his whistling.
C. He did not have a large enough sample size.

Beaker A The egg floated. Beaker B The egg sank. What might the students conclude from the observations? A. The eggs are different sizes. B. Both beakers were filled with water only. C. Both beakers A and B used the same size egg. D. Beaker A had an unknown dissolved substance.
D. Beaker A had an unknown dissolved substance. Additional substances would allow one egg to sink and another to float.
