Grade 7 Science Q4 - Earth and Space Science
-featured.png)
This course examines Earth as an interconnected system with a Philippine focus: spheres of Earth, fault mechanics and seismic waves, magnitude vs intensity and PHIVOLCS-based local risk assessment, tsunami science and response, solar drivers of weather, and orbital controls on seasons, monsoons and the ITCZ. Through practical activities and local data use, learners build the knowledge and skills to evaluate hazards and strengthen community preparedness.

What you'll learn
- Define a system and identify the major interconnected subsystems (spheres) of the Earth, explaining how their interactions produce observable natural phenomena.
- Classify the three main geological faults (normal, reverse, and strike-slip) and use models to explain how rapid movements along these fault planes generate seismic waves and earthquakes.
- Distinguish between earthquake magnitude and intensity (using the PEIS), and use reliable secondary data, such as the PHIVOLCS FaultFinder, to assess the earthquake risk for their local community.
- Explain how underwater seismic activity generates tsunamis, describe the procedures for tsunami alerts, and demonstrate the appropriate actions to take during and after an earthquake or tsunami event based on local disaster readiness plans.
- Explain how energy from the Sun interacts with the Earth's atmosphere and demonstrate how this interaction contributes to local weather phenomena like land and sea breezes.
- Construct a model explaining how the Earth’s tilt, revolution, and rotation influence the patterns of day/night and seasons, and use this knowledge to explain the dominant processes that influence the climate of the Philippines (monsoons, ITCZ).
