Study Notes
Types of Science
- Sciences can be categorized into various branches: Astronomy, Chemistry, Physics, and Biology.
- Natural Science encompasses the study of natural phenomena through observation and experimentation.
Pure vs. Applied Science
- Pure Science aims to expand knowledge without immediate practical applications.
- Applied Science utilizes knowledge gained from pure science to solve real-world problems, often focusing on product or service development.
Scientific Reasoning
- Discovery Science employs inductive reasoning, which involves deriving general principles from specific observations.
- Hypothesis-based Science uses deductive reasoning, starting with a broad understanding to formulate specific, testable hypotheses.
Inductive vs. Deductive Reasoning
- Inductive reasoning generates generalizations based on observations of natural processes.
- Deductive reasoning begins with a known principle to make predictions about specific scenarios.
Experimental Design
- Controlled experiments maintain constant conditions across all parameters to isolate the effect of the independent variable.
- An experimental group tests the independent variable, while a control group serves as a baseline comparison.
Hypothesis and Theories
- A hypothesis must be testable and falsifiable, providing a basis for scientific inquiry.
- Scientific theories are well-supported frameworks that withstand repeated testing and are backed by significant evidence.
Notable Theories in Biology
- The Cell Theory states that all living organisms are composed of one or more cells, which are the basic units of life.
- Other significant concepts include Chromosome Theory, underlying genetic inheritance, and the theory of evolution.
Evidence and Support for Theories
- Theories are validated through a robust body of evidence gathered from multiple experiments and observations, reinforcing their credibility within the scientific community.
