Introduction to Science and Its Branches

Definition

• Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Branches of Science

1. Physical Sciences

   • Physics: Study of matter, energy, and the fundamental forces.
   • Chemistry: Study of substances, their properties, and reactions.
   • Earth Science: Study of the Earth, its structure, processes, and history.

2. Life Sciences

   • Biology: Study of living organisms, their structure, function, growth, and evolution.
   • Zoology: Study of animals and their behaviors.
   • Botany: Study of plants.

3. Social Sciences

   • Psychology: Study of mind and behavior.
   • Sociology: Study of society and social behavior.
   • Economics: Study of the production, distribution, and consumption of goods and services.

Scientific Method

1. Observation: Noticing and describing phenomena.
2. Question: Asking a question about the observations.
3. Hypothesis: Formulating a testable explanation.
4. Experimentation: Testing the hypothesis through controlled experiments.
5. Analysis: Analyzing data to determine whether it supports the hypothesis.
6. Conclusion: Drawing conclusions based on the analysis.
7. Communication: Sharing findings with the scientific community.

Key Concepts

• Theory vs. Law:

  • Theory: A well-substantiated explanation of an aspect of the natural world.
  • Law: A statement based on repeated experimental observations that describe an aspect of the world.

• Variables:

  • Independent Variable: The variable that is manipulated in an experiment.
  • Dependent Variable: The variable that is measured or affected in an experiment.

• Control: A standard for comparison that remains unchanged throughout the experiment.

Importance of Science

• Advances technology and medicine.
• Informs public policy and environmental conservation.
• Drives education and promotes critical thinking.
• Enhances understanding of natural phenomena.

Current Trends

Science's Key Concepts: Understanding the Language

• Theory vs. Law represent different levels of scientific understanding.
  • Theory is a well-substantiated explanation of an aspect of the natural world, supported by extensive evidence.
  • Law is a statement based on repeated observations that describes a consistent pattern in nature.
• Variables are crucial elements in experiments.
  • Independent Variable is the factor manipulated during an experiment to observe its effect.
  • Dependent Variable is the factor measured or observed in response to changes in the independent variable.
• Control serves as a standard for comparison, remaining unchanged throughout the experiment, providing a baseline for analysis.

The Importance of Science: Impact on the World
