This Lesson pertains to the learning competency that would engage the students to explain that the Earth consists of four subsystems, across whose boundaries matter and energy flow. The activities would enable the students to determine the four subsystems of the Earth and help them differentiate the subsystems based on their characteristics. Also, the activities would enable the students to explain how matter and energy flow in the subsystems. They would also be able to trace the flow of matter and energy across the subsystems. This would also help them to internalize the role of humans in the unstoppable flow of matter and energy in the subsystems. This would also help the students intensify their roles as stewards of each subsystem.
The module contains discussions on Earth’s Subsystems and the flow of matter and energy in these subsystems.
After going through this module, you are expected to:
1. identify the four subsystems of the earth;
2. distinguish the characteristics of each subsystem;
3. explain how matter and energy flow in the subsystems; and
4. trace the flow of matter and energy in the subsystems.earthscienceforstem_q1_mod2_earthssubsystem_v2
