Study Notes
Environmental Science Overview
- Environmental science investigates the Earth's complex systems, combining biology, geology, chemistry, and natural sciences.
- It can also incorporate social sciences, including economics and political science.
- Research in environmental science is conducted both individually and collaboratively by a community of researchers.
Methods of Science
- Key scientific methods: observation, logical reasoning, experimentation, and peer scrutiny.
- Creativity and imagination are crucial for designing effective experiments.
- Science can serve practical applications, such as enhancing agricultural practices, or be driven by curiosity.
Definition and Scope of Science
- Science, derived from the Latin "scientia," refers to knowledge regarding the natural world.
- It is a systematic process for acquiring knowledge rather than a mere collection of facts and theories.
- Historical developments in the last 500 years highlight science's pivotal role in technological advancement.
Limitations of Science
- Science cannot address purely moral, aesthetic, or spiritual questions as they fall outside material phenomena that can be observed and measured.
Scientific Method and Hypotheses
- The scientific method involves defined steps, emphasizing hypothesis testing as a core component.
- A hypothesis offers a testable explanation for an event and is developed within the context of a scientific theory.
- Scientific theories are thorough, well-tested explanations for sets of observations, while scientific laws describe natural phenomena, often using mathematical formulations.
Relationship Between Hypotheses, Theories, and Laws
- Misconception: hypotheses do not evolve into theories and then into laws; they coexist within the framework of scientific understanding.
- Theories encompass multiple hypotheses and established facts, while laws provide concise descriptions of relationships within nature (e.g., Newton’s Law of Gravity).
Natural Sciences Definition
- Natural sciences study the physical world and its processes, integrating fields such as astronomy, biology, chemistry, and physics.
- A natural science museum could feature a variety of exhibits, including fossils, plant displays, and astronomical phenomena.
- Definitions of natural sciences vary; they may be categorized into life sciences (studying living organisms) and physical sciences (studying nonliving matter).
Interdisciplinary Disciplines
- Disciplines like biophysics and biochemistry bridge gaps between life and physical sciences, enriching the broader scientific landscape.
