Introduction to Science Quiz

Definition of Science

• Systematic study of the natural world.
• Based on observation, experimentation, and evidence.

Branches of Science

1. Physical Sciences

   • Physics: Study of matter, energy, and their interactions.
   • Chemistry: Study of substances, their properties, and reactions.
   • Astronomy: Study of celestial bodies and the universe.

2. Life Sciences

   • Biology: Study of living organisms and their interactions.
   • Ecology: Study of ecosystems and environmental interactions.
   • Genetics: Study of heredity and variation in organisms.

3. Earth Sciences

   • Geology: Study of the Earth’s structure, processes, and history.
   • Meteorology: Study of weather and atmospheric phenomena.
   • Oceanography: Study of oceans and marine systems.

4. Formal Sciences

   • Mathematics: Study of numbers, quantities, and shapes.
   • Logic: Study of reasoning and argumentation.
   • Computer Science: Study of computation and information processing.

Scientific Method

1. Observation: Identifying a phenomenon or problem.
2. Research: Gathering existing information.
3. Hypothesis: Formulating a testable explanation.
4. Experimentation: Testing the hypothesis through controlled experiments.
5. Analysis: Interpreting data and results.
6. Conclusion: Drawing conclusions based on experimental evidence.
7. Communication: Sharing findings with the scientific community.

Key Concepts in Science

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describes some aspect of the universe.
• Variable: Any factor that can change in an experiment.
  • Independent Variable: The factor that is manipulated.
  • Dependent Variable: The factor that is measured.
• Control Group: The group that does not receive the experimental treatment for comparison.

Importance of Science

• Advances understanding of the natural world.
• Drives technological innovation and development.
• Informs policy-making and public health decisions.
• Enhances critical thinking and problem-solving skills.

Scientific Method

• Observation: Identifying a problem or phenomenon to study.
• Research: Collecting existing information related to the problem.
• Hypothesis: Creating a testable explanation for the observation.
• Experimentation: Conducting controlled tests to evaluate the hypothesis.
• Analysis: Interpreting the collected data and results from experiments.
• Conclusion: Drawing conclusions based on the evidence obtained.
• Communication: Sharing findings with the scientific community for validation.

Key Concepts in Science

• Theory: A robust explanation supported by substantial evidence regarding a natural phenomenon.
• Law: A concise statement derived from repeated observations that describes an aspect of the universe.
• Variable: Any element that can change during an experiment.
• Independent Variable: The factor deliberately manipulated in an experiment.
• Dependent Variable: The factor measured to assess the impact of the independent variable.
• Control Group: A baseline group that does not undergo experimental changes for comparison.

Importance of Science

• Expands knowledge of the natural world and its phenomena.
• Fuels innovation and advances in technology.
• Provides essential insights for policymaking and public health strategies.
• Cultivates critical thinking and enhances problem-solving capabilities.
