• The competition makes the scientist work more carefully

• More than one scientist is interested in the problem

• Different scientists might perform perform the experiment differently

Scientists use different methods to carry out their research. Which of these does NOT describe

systematic observation?

• It is the part of an experiment in which measurements and data are collected.

• It is different from the casual observation needed to recognize patterns in an experiment.

• It is a method of investigation to use in place of an experiment.

• It may be an appropriate method when the scientist doesn’t need to compare two groups.

A scientist observes previously unexplained curved lines etched in rocks in the Negev Desert.

Which creative method below would explain how the scientist discovered that snails were carving the lines each night as they feed on lichens that grew on the rocks?

• The scientist researched in the library to discover if other rocks had similar lines

• The scientist gathered empirical evidence by recording a video of what happened on the rocks 24 hours a day.

• The scientist moved a rock into the laboratory to study its composition.

• The scientist found rocks of similar sizes in other locations.
