Study Notes
Branches of Science
-
Natural Sciences:
- Biology: study of living organisms and their interactions
- Chemistry: study of the composition, properties, and reactions of matter
- Physics: study of the natural world around us, including energy, matter, and the fundamental laws of the universe
-
Formal Sciences:
- Mathematics: study of numbers, quantities, and shapes
- Logic: study of reasoning, argumentation, and inference
-
Applied Sciences:
- Engineering: application of scientific knowledge to design, build, and maintain structures, machines, and systems
- Medicine: application of scientific knowledge to the prevention, diagnosis, and treatment of diseases
Scientific Method
- Observation: making an observation about the world around us
- Question: asking a question about what we have observed
- Hypothesis: proposing a possible explanation for what we have observed
- Prediction: making a prediction based on our hypothesis
- Experiment: designing and conducting an experiment to test our hypothesis
- Analysis: analyzing the data collected during the experiment
- Conclusion: drawing a conclusion based on the results of the experiment
Scientific Theories
- A scientific theory is a well-substantiated explanation for a set of phenomena
- Theories are not just guesses, but rather are based on a large amount of evidence and testing
- Examples of scientific theories include:
- Evolution
- Gravity
- Atomic Structure
Scientific Tools and Techniques
- Measurement: using instruments to measure physical quantities such as length, mass, and time
- Microscopy: using microscopes to study microorganisms and cells
- Chromatography: separating and identifying the components of a mixture
- Spectroscopy: studying the interaction between matter and electromagnetic radiation

Scientific Method
- Scientific method is a systematic process used to develop and test scientific knowledge
- It involves making an observation, asking a question, proposing a hypothesis, making a prediction, designing and conducting an experiment, analyzing data, and drawing a conclusion
