Physical Science Quiz: Matter & Chemical Reactions

Physical Science

• Matter:

  • Matter is anything that occupies space and has mass.
  • States of matter: solid, liquid, gas, and plasma.
  • Properties of matter: physical (color, odor, density, melting point, boiling point) and chemical (reactivity, flammability).
  • Changes of state: melting, freezing, vaporization, condensation, sublimation, deposition.
  • Atom: the fundamental unit of matter.
  • Molecules: formed by the combination of two or more atoms.
  • Elements: substances composed of only one type of atom.
  • Compounds: formed by the chemical combination of two or more elements in a fixed ratio.
  • Mixtures: combinations of two or more substances in varying proportions.
  • Law of Conservation of Mass: matter cannot be created or destroyed, only transformed.
  • Atomic Structure: Nucleus (protons, neutrons), Electrons.

• Chemical Reactions:

  • Chemical equations: represent chemical reactions using symbols and formulas.
  • Types of chemical reactions: synthesis, decomposition, single displacement, double displacement, combustion.
  • Balancing chemical equations: making sure the number of atoms of each element is the same on both sides of the equation.
  • Acids, bases and salts: their properties and reactions (neutralization).
  • Indicators: substances that change color in the presence of acids or bases.
  • pH scale: measures the acidity or alkalinity of a substance (0-14).
  • Redox Reactions: involve transfer of electrons between reactants.

Biology

• Living Organisms:

  • Characteristics of living organisms: organization, growth, reproduction, metabolism, responsiveness, adaptation.
  • Cell: basic unit of life.
  • Cell theory: all living organisms are composed of cells.
  • Types of cells: prokaryotic and eukaryotic.
  • Cell organelles: their structure and functions (e.g. nucleus, mitochondria, chloroplasts).

• Plant Kingdom:

  • Diversity of plants: different plant groups (e.g. gymnosperms, angiosperms).
  • Photosynthesis: process by which plants make their own food using sunlight, water, and carbon dioxide.
  • Respiration in plants: the process by which plants release energy from stored food.
  • Reproduction in plants: sexual and asexual methods.
  • Adaptations of plants to their environment.

• Animal Kingdom:

  • Diversity of animals: different animal groups (vertebrates, invertebrates).
  • Characteristics of different animal groups.
  • Nutrition in animals: heterotrophic nature.
  • Respiration in animals: different methods (lungs, gills, skin).
  • Excretion in animals: removal of waste products.
  • Reproduction in animals: sexual and asexual methods.
  • Adaptations of animals to their environment.
  • Human digestive system, respiratory system, circulatory system, excretory system.

Physics

• Motion:

  • Distance, displacement, speed, velocity, acceleration.
  • Equations of motion.
  • Uniform and non-uniform motion.
  • Graphs of motion (distance-time, speed-time graphs).

• Laws of Motion:

  • Newton's laws of motion (first, second, third).
  • Force, mass, inertia, momentum.
  • Types of forces (gravitational, frictional, muscular).

• Gravitation:

  • Gravity as a force.
  • Law of universal gravitation.
  • Weight and mass.
  • Acceleration due to gravity.

• Work, Energy and Power:

  • Work, energy, power.
  • Types of energy (kinetic, potential, heat).
  • Conservation of energy.

• Simple Machines:

  • Understanding levers, pulleys, inclined planes.

Chemistry (Further details)

• Chemical Bonding:

  • Types of bonds: ionic, covalent, and metallic.
  • Properties of different compounds based on bonding.
  • Molecular structure and shape.

• Acids, Bases, and Salts (extended):

  • Arrhenius, Bronsted-Lowry definitions of acids and bases.
  • Strong and weak acids and bases; their properties.
  • Titration: a technique to determine the concentration of an unknown solution.

• Chemical Reactions (types and kinetics):

  • Rate of Reactions, Factors affecting Rates of Reactions: Temperature, Concentration, Surface Area, Catalysts.
  • Reversible Reactions and Equilibria.

Biology (Further details)

• Ecosystems:

  • Components of an ecosystem (biotic and abiotic factors).
  • Food chains, food webs.
  • Energy flow and nutrient cycling.
  • Types of ecosystems (forest, grassland, desert, aquatic).
  • Human impact on ecosystems and conservation.

• Human Health and Diseases:

  • Basic concepts of diseases, immunity.
  • Infectious and non-infectious diseases
  • Importance of hygiene and sanitation.
  • Communicable vs non-communicable diseases.

Practical Skills

• Scientific Method:
  • Observation, hypothesis formation, experimentation, data analysis, conclusions.
  • Representing data using graphs, tables, charts.
  • Accuracy and precision in measurements.
