Study Notes
Nature of Science
- Science is a systematic approach to learning about the natural world using evidence and logic.
- Scientists investigate both small entities (like atoms and molecules) and large entities (such as the sun and stars).
- Scientific knowledge is dynamic, evolving through major breakthroughs and gradual advancements over time.
Scientific Theory and Scientific Law
- A scientific theory is a comprehensive explanation of an aspect of the natural world, supported by substantial evidence (e.g., atomic theory, theory of general relativity).
- A scientific law describes consistent outcomes under specific conditions, exemplified by Newton's laws and conservation laws.
Nature of Technology
- Technology applies scientific knowledge to solve practical problems and continues to evolve through innovative materials, designs, or processes.
- The process of technological design mirrors scientific investigation, involving logical steps based on evidence and reason.
Investigations in Science
- The scientific method entails a sequence of steps: Observation, Research, Hypothesis, Experiment, Analysis, Conclusion, and Communication.
- An example of applying the scientific method is exploring why plants show varying growth patterns in different garden sections.
- Observations are made through sensory methods or using tools like microscopes and thermometers.
Scientific Hypothesis
- A scientific hypothesis is a testable and falsifiable educated guess that predicts outcomes based on initial observations.
Measurement System
- The International System of Units (SI) is the standardized measurement system predominantly utilized by scientists and engineers, featuring units like meters for length and kilograms for mass.
- Accuracy refers to closeness of a measurement to the true value, while precision indicates the closeness between repeated measurements.
Ethical Considerations
- Ethical considerations in science involve making informed and responsible choices, navigating the space between right and wrong in research and innovation.
