Students studying science, including professors, should observe, deduce, forecast, communicate, apply ideas, and ask questions.
When appropriate, they should interpret data, categorize, control variables, operationalize definitions, conduct experiments, develop models, and develop hypotheses.
Any science—physical, biological, earth, environmental, STEM—can be used to support this.
The more often this is done, the more obvious the connections between the many fields of study (and other subjects) become, and the more profound the comprehension and problem-solving skills become.
