Course Description: 

          At the end of Grade 9, the learners have gained a deeper understanding of the respiratory, and circulatory systems to promote overall health. They have become familiar with some technologies that introduce desired traits in economically important plants and animals. Learners can explain how new materials are formed when atoms are rearranged. They recognize that a wide variety of useful compounds may arise from such rearrangements. Learners can identify volcanoes and distinguish between active and inactive ones. They can explain how energy from volcanoes may be tapped for human use. They are familiar with climatic phenomena that occur on a global scale. They can explain why certain constellations can be seen only at certain times of the year.  Learners can predict the outcomes of interactions among objects in real life applying the laws of conservation of energy and momentum.

OBJECTIVES:

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

  1. Identify the different parts of the respiratory and the cardiovascular system.
  2. Discuss the function of each part of the respiratory and the circulatory system.
  3. Explain how the respiratory and the circulatory systems work together to transport nutrients, gases, and the other molecules to and from the different parts of the body.
  4.  Infer how one’s lifestyle can affect the functioning of the respiratory and the circulatory systems.
  5. Explain the different patterns of non-Mendelian inheritance.
  6. Relate species extinction to the failure of populations or organisms to adapt to abrupt changes in the environment.
  7. Differentiate basic features and importance of photosynthesis and respiration.
