Senior High School Core Subject: Physical Science

Physical science is one of the core subjects of the senior high school curriculum. Some examples of the things that you will learn from taking this subject include:


  • How the elements found in the universe were formed
    • The formation of the elements during the Big Bang and during stellar evolution
    • The distribution of the chemical elements and the isotopes in the universe
  • How the idea of the atom, along with the idea of the elements evolved
  • How the properties of matter relate to their chemical structure
    • How the uses of different materials are related to their properties and structures
    • The relationship between the function and structure of biological macromolecules
  • How chemical changes take place
    • how fast a reaction takes place
    • how much reactants are needed and how much products are formed in a reaction
    • how much energy is involved in a reaction
  • How chemistry contributes to the understanding of household and personal care products
    • The properties and mode of action of the following consumer products:
      • cleaning materials
      • cosmetics
  • How we discovered that the Earth is not the center of the Universe
  • Why the laws of physics are universal
    • Greek views of matter, motion, and the universe
    • Competing models of the universe by Eudoxus, Aristotle, Aristarchus, Ptolemy, Copernicus, Brahe, and Kepler
    • Evidence that the Earth is not the center of the universe
  • How light acts as a wave and a particle
  • How physics helps us understand the cosmos
    • Relativity and the Big Bang
    • Planets in and beyond the solar system

While studying, you will also be asked to demonstrate what you have learned by participating in class activities that may include the following:

  • Explaining the formation of the light elements in the Big Bang theory
  • Writing nuclear fusion reactions that take place in stars
  • Calculating the amount of substances used or produced in a chemical reaction
  • Describing the nuclear model of the atom and the location of its major components
  • Calculating the amount of substances used or produced in a chemical reaction
  • Identifying the major ingredients of cosmetics

These examples only cover the scope of the core subjects. For the scope of the contextualized and specialized subjects, please refer to their respective lists.
