Course Description

Science 7 deals with the difference of mixtures from substances through semi-guided investigations, how organ systems work together in plants and animals in the lower grade levels, the use a microscope when observing very small organisms and structures, the organization of life into different levels: cells, tissues, organs, organ systems, and organisms. It explains that the motion of objects in terms of distance and speed, and represent this in tables, graphs, charts, and equations, the cause on how various forms of energy travel through different mediums, describes what makes up the Philippines as a whole and the resources found in the archipelago, explains the occurrence of breezes, monsoons, and ITCZ, and how these weather systems affect people and lastly, it explains why seasons change and demonstrate how eclipses occur.

I. Objectives

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

  1. describe the motion of an object in terms of distance or displacement, speed or velocity and acceleration;
  2. create and interpret visual representation of the motion of the motion of objects such as tape charts and motion graphs;
  3. infer that waves carry waves;
  4. describe the characteristics of sound using the concept of wavelength, velocity and amplitude;
  5. explain color and intensity of light in terms of its wave characteristics;
  6. describe the different infer the conditions necessary for heat transfer to occur;
  7. types of charging processes.
