Match the following Steps in the Scientific Method: Salt Marsh Experiment

• Inferring and Hypothesizing

• The researchers inferred that something limits grass growth in some places.

• Drawing Conclusions

• The researchers sampled all the plots throughout the growing season

• Collecting and Analyzing Data

• Data from all plots were compared and evaluated by statistical tests.

• Observing and Asking Questions

• Researchers observed that marsh grass grows taller in some places than others.
