Grade 9 Science Module: Geothermal Energy

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

You’ve learned from previous lesson that Heat, as a form of energy has many practical applications in our daily lives; cooking, heating and cooling, and generating electricity all depend on energy transformations that end by transferring heat energy.

This module will help you learn how heat transfer and energy transformations make heat engines like Geothermal Plants work. The children will learn how electrical energy is being generated in a Geothermal Power Plants. Learners will do some activities and simple experiments.

For us to do it, we will go through the following lesson:

Lesson 1: Geothermal Energy

At the end of this lesson, you will be able to explain how heat transfer and energy transformation make heat engines like geothermal plant works.

Specifically, after going through this module, you will be able to:

1. Identify the location of some Geothermal Power plants in the Philippine map.

2. Trace the energy transformations from thermal energy up to the generation of electrical energy in a Geothermal power plant.
