Course Description

Science 8 deals with the motion of an object based on the Laws of Motion, concept of work, transfer of energy, such as temperature difference, and the types of the medium. It includes how active faults generate earthquakes and, how tropical cyclones originate from warm ocean waters. It explains the behavior of matter in terms of the particles it is made of, the ingredients in food and medical products are made up of these particles and are absorbed by the body in the form of ions. It explains that reproduction as a process of cell division resulting in growth of organisms delves deeper into the process of digestion, giving emphasis on proper nutrition for overall wellness.

I. Objectives

            At the end of the unit, the students will be able to:

  1. explain the properties of solids, liquids, and gases based on the particle nature of matter;
  2. explain physical changes in terms of the arrangement and motion of atoms and molecules;
  3. realize the importance of structure of matter and society
  4. determine the number of protons, neutrons, and electrons in a particular atom;
  5. explain the use of isotopes in disease diagnosis and treatment.
  6. use the periodic table to predict the chemical behavior of an element
  7. accept the “periodicity” in one’s life and in others’
