General Science Overview

General Science Study Notes

Definition

• General science is an umbrella term encompassing various scientific disciplines, including natural, physical, and social sciences.

Branches of General Science

1. Natural Sciences

   • Focus on the study of the natural world.
   • Includes:
     • Biology: Study of living organisms and life processes.
     • Chemistry: Study of substances, their properties, and reactions.
     • Physics: Study of matter, energy, and the fundamental forces of nature.
     • Earth Science: Study of the Earth, including geology, meteorology, and oceanography.

2. Physical Sciences

   • Concerned with non-living systems.
   • Includes:
     • Astronomy: Study of celestial bodies and the universe.
     • Chemistry: (also part of natural sciences) Focus on chemical reactions and compounds.

3. Social Sciences

   • Study of human behavior and societies.
   • Includes:
     • Psychology: Study of mind and behavior.
     • Sociology: Study of societal structures and relationships.
     • Economics: Study of production, distribution, and consumption of goods.

Scientific Method

• A systematic approach to inquiry and problem-solving.

1. Observation: Gather information through senses.
2. Question: Identify a question based on observations.
3. Hypothesis: Propose a testable explanation.
4. Experimentation: Conduct experiments to test the hypothesis.
5. Analysis: Analyze data and draw conclusions.
6. Reporting: Share findings with the scientific community.

Key Concepts

• Matter: Anything that has mass and occupies space.
• Energy: The capacity to do work; can exist in various forms (kinetic, potential, thermal).
• Ecosystems: Interactions between living organisms and their environment.
• Evolution: The process through which species change over time via natural selection.

Important Tools in Science

• Microscope: Used to magnify small objects.
• Telescope: Used to observe distant celestial objects.
• Balancing Scales: Used to measure mass.
• Thermometers: Measure temperature.
• pH Meters: Measure acidity or alkalinity of solutions.

Scientific Principles

• Conservation Laws: Matter and energy can neither be created nor destroyed.
• Law of Gravity: Every mass attracts every other mass.
• Theory of Relativity: Describes the relationship between space, time, and gravity.

Importance of General Science

• Enhances understanding of the world.
• Promotes critical thinking and problem-solving skills.
• Provides a foundation for technological advancements and innovations.

Definition
