• Problem Solving: Provides tools and methodologies for solving real-world problems related to energy, resources, and environmental issues.

The Scientific Method

• Definition: A systematic process used by scientists to explore observations, answer questions, and test hypotheses.

• Steps in the Scientific Method:

  • Observation: Gathering information through the senses.

  • Question: Formulating a question based on observations.

  • Hypothesis: Proposing an explanation that can be tested.

  • Experiment: Conducting tests to support or refute the hypothesis.

  • Analysis: Interpreting the data collected during experiments.

  • Conclusion: Drawing conclusions based on the analysis and sharing findings with the scientific community.

• Importance of Reproducibility: Scientific experiments should be reproducible by other researchers to validate results.

Conclusion

• Physical science plays a critical role in advancing knowledge and fostering innovation across various fields.
