Grade 9 Science Q2 - Earth and Space Science
-featured.png)
This course covers Earth and space science in six modules: Earth's structure and internal heat, plate tectonics with Philippine examples, geologic time and dating methods, Solar System formation, small bodies, and modern space technologies. Learners build scale models, analyze seismic and fossil evidence, practice radiometric reasoning, and evaluate space instruments. Emphasizing inquiry and local relevance, it equips students to interpret Earth’s processes, planetary origins, and the tools scientists use to explore the cosmos.
Meet Your Instructors
What you'll learn
- Create a scale drawing representing the layers of the Earth's interior (crust, mantle, core) and explain how radioactive decay serves as the planet's internal source of energy.
- Identify and explain the geological evidence supporting Continental Drift and collaboratively describe the topographical and geological features found at different plate boundaries, focusing on the Philippine setting.
- Describe how fossils and radioactive dating techniques are used to determine the age of rocks and explain how the Geologic Time Scale organizes the major stages in Earth's history.
- Evaluate observable evidence and models to explain the accepted theory for the formation and organization of the Solar System.
- Distinguish among comets, meteoroids, asteroids, and dwarf planets, and gather information to discuss the regular occurrence of meteor showers.
- Explain how modern research about celestial objects uses new space technologies, including advanced telescopes and robotic space probes.
