Course Description: 

                              Science 9, provides a deeper understanding of the respiratory, and circulatory systems to promote overall health, technologies that introduce desired traits in economically important plants and animals, new materials formed when atoms are rearranged and recognizes a wide variety of useful compounds. It gives information about volcanoes, explains how energy from volcanoes may be tapped for human use, and climatic phenomena that occur on a global scale. It also explains why certain constellations can be seen only at certain times of the year and discuss the outcomes of interactions among objects in real-life applying the laws of conservation of energy and momentum.

OBJECTIVES:

At the end of the second quarter, the students are expected to:

  1. use the mole concept to express the mass of substances;
  2. determine the percentage composition of a compound given its chemical formula and vice versa;
  3. explain how the structure of carbon atom affects the type of bonds it forms;
  4. recognize the general classes and uses of organic compounds;
  5. discuss what happens when volcanoes erupt ;
  6. illustrate how energy from volcanoes may be tapped for human use; 
  7. explain how different factors affect the climate of an area;
  8. describe certain climatic phenomena that occur on a global level;
  9. infer the characteristics of stars based on the characteristics of the Sun;
  10. infer that the arrangement of stars in describe the different types of volcanoes;
  11. differentiate between active and inactive volcanoes;
  12. explain what a group (constellation) does not change;
  13. observe that the position of a constellation changes in the course of a night; and
  14.  show which constellations may be observed at different times of the year using models.
