Fundamental Science Concepts

The Speed of Light:
- Travels at approximately 299,792 kilometers per second (186,282 miles per second) in a vacuum, representing the ultimate speed limit in the universe.
Human DNA:
- Comprises roughly 3 billion base pairs, with over 99% being identical among all humans, highlighting genetic similarities across the species.
The Water Cycle:
- Includes key processes such as evaporation, condensation, precipitation, and collection, essential for maintaining Earth's ecosystems.
- Water exists in three states: solid (ice), liquid (water), and gas (water vapor), all integral to the cycle.
Periodic Table:
- Consists of 118 confirmed elements categorized by atomic number, enabling systematic study of chemical properties.
- Groups elements with similar properties in vertical columns known as groups or families.
Newton's Laws of Motion:
- First Law: An object in motion remains in motion unless acted upon by an external force, establishing the concept of inertia.
- Second Law: Force (F) equals mass (m) times acceleration (a), expressed as F = ma, demonstrating the relationship between force and motion.
- Third Law: For every action, there is an equal and opposite reaction, emphasizing interaction forces in physical systems.
Photosynthesis:
- A vital process in which plants convert sunlight into chemical energy, producing glucose and oxygen.
- Chemical equation: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2, illustrating the transformation of carbon dioxide and water into glucose and oxygen.
Atoms and Molecules:
- Atoms, the fundamental units of matter, consist of protons, neutrons, and electrons.
- Molecules form when two or more atoms bond together, creating various substances.
The Universe:
- Estimated to be about 13.8 billion years old, containing billions of galaxies, each with millions to billions of stars, highlighting its vastness.
Gravity:
- A fundamental force that attracts two bodies towards each other, dependent on their masses and inversely proportional to the square of the distance between them.
Evolution by Natural Selection:
- Introduced by Charles Darwin, explaining that species adapt over time through genetic variations, leading to the survival of the fittest.
Chemical Reactions:
- Occur when reactants transform into products, often accompanied by energy changes, essential for biological and physical processes.
Electricity:
- The flow of electric charge, primarily carried by electrons in conductors, fundamental to modern technology.
- Measured in volts (V), amperes (A), and ohms (Ω), representing voltage, current, and resistance respectively.
Climate Change:
- Involves significant alterations in global temperatures and weather patterns, primarily driven by human activities like burning fossil fuels and deforestation.
The Scientific Method:
- A structured approach for conducting experiments and making observations, consisting of steps: observation, hypothesis formation, experimentation, analysis, and conclusion.
Cell Theory:
- Asserts that all living organisms are composed of cells, the basic unit of life; additionally, cells originate only from pre-existing cells, emphasizing the continuity of life.
