Study Notes
Branches of General Science
-
Physical Science
- Studies non-living systems.
- Includes physics and chemistry.
-
Life Science
- Focuses on living organisms.
- Includes biology, botany, and zoology.
-
Earth Science
- Examines Earth and its components.
- Includes geology, meteorology, and oceanography.
Scientific Method
- Observation: Gather data through the senses.
- Hypothesis: Formulate a testable explanation.
- Experimentation: Test the hypothesis with controlled experiments.
- Analysis: Interpret the data collected.
- Conclusion: Draw conclusions based on the analysis.
- Report: Share findings for peer review.
Basic Concepts
-
Atoms & Molecules
- Atoms: Basic units of matter.
- Molecules: Combinations of two or more atoms.
-
Cells
- Basic unit of life.
- Types: Prokaryotic (no nucleus) and Eukaryotic (with nucleus).
-
Ecosystems
- Community of living organisms interacting with their environment.
- Biotic (living) and abiotic (non-living) factors.
Important Laws and Theories
-
Newton's Laws of Motion
- 1st: An object at rest stays at rest unless acted upon.
- 2nd: Acceleration is dependent on force and mass (F=ma).
- 3rd: For every action, there is an equal and opposite reaction.
-
Law of Conservation of Mass
- Mass is neither created nor destroyed in a chemical reaction.
-
Theory of Evolution
- Explains the diversity of life through natural selection.
Measurements in Science
-
Metric System
- Standard measurement system used globally.
- Units: meter (length), liter (volume), gram (mass).
-
SI Units
- International System of Units.
- Base units include meter (m), kilogram (kg), second (s), ampere (A).
Key Scientific Instruments
- Microscope: Magnifies small objects for study.
- Telescope: Allows observation of distant celestial bodies.
- Balance: Measures mass with precision.
Current Topics in General Science

- Genetic Engineering: Manipulation of an organism's DNA.
- Renewable Energy: Sustainable energy sources like solar, wind, and hydro.
Basic Scientific Notation
- Used to express very large or very small numbers.
- Format: ( a \times 10^n ), where ( 1 \leq a < 10 ) and n is an integer.

- Experimentation tests the hypothesis using controlled experiments.
- Analysis involves interpreting the data collected during the experiment.
- Conclusion is drawn based on the analysis of the data.
- Report shares the findings for peer review and further scientific inquiry.
Basic Concepts
- Atoms are the basic units of matter.
- Molecules are combinations of two or more atoms.
- Cells are the basic unit of life, classified as prokaryotic (lacking a nucleus) or eukaryotic (containing a nucleus).
- Ecosystems consist of communities of living organisms interacting with their environment, including biotic (living) and abiotic (non-living) factors.
Important Laws and Theories
-
Newton's Laws of Motion describe the relationship between force, mass, and motion:
- 1st Law: An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- 2nd Law: The acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass (F=ma).
- 3rd Law: For every action, there is an equal and opposite reaction.
- Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction.
- Theory of Evolution explains the diversity of life through natural selection, where organisms best adapted to their environment are more likely to survive and reproduce.
Measurements in Science
- Metric System is the standard system of measurement used globally, employing units like meter (length), liter (volume), and gram (mass).
- SI Units (International System of Units) provides a standardized basis of measurement, with base units including meter (m), kilogram (kg), second (s), and ampere (A).
Key Scientific Instruments
- Microscope magnifies small objects for detailed study.
- Telescope assists in observing distant celestial bodies.
