Learning Objectives
These are the target outcomes that we hope you will be able to do by the end of the module:
1. Describe the different methods of dating and how they are used to determine geologic time
2. Recognize the uniqueness of Earth, being the only planet in the solar system with properties necessary to support life
3. Explain that the earth consists of four subsystems, across whose boundaries matter & energy flow
4. Identify and differentiate the layers of the earth (crust, mantle, core)
5. Develop keenness in observation of data (physical or digital)
Watch one of the episodes of Our Planet on Netflix (or YouTube).
What episode did you choose to watch? Based on what you saw, compare your observations about the earth and your knowledge about the other planets in the solar system. What is unique to the earth?
Share your answer in the Google Classwork Question 📚
Our planet Earth is truly unique because it is the only planet in the solar system that can naturally support life, specifically human life.
How much do you know about our mother earth? What are the factors that contribute to the uniqueness of our planet? When was the earth “born”?
KEY CONCEPT 1
KEY CONCEPT 1
Scientists use various techniques to know the age of the earth and determine geologic time.
Scientists use various techniques to know the age of the earth and determine geologic time.
What are these various techniques? Use these two articles from National Geographic about the research archeologists and scientists have been doing in Turkana Basin, Kenya, to identify the different techniques. Write them down in your notebooks.
Watch this video by GNS Science in New Zealand to see how they do their studies on rocks and the Ted-Ed video on the origin of water.
Did you encounter scientific concepts that you've learned already in the past Science classes? Be ready to share your answers during the VOC 😊

The earth is a system with four subsystems.
The earth is a system with four subsystems.
What is a system? It is a set of interconnected components that are interacting to form a unified whole.
The Earth system is essentially a closed system. It receives energy from the sun and returns some of this energy to space. It is a closed system in which there is only an exchange of heat or energy and no exchange of matter.
Research on the subsystems of the earth. How many are there and what are they?
Test your knowledge and try to identify the subsystems using the learning app:
What are the characteristics of each subsystem? How do the four subsystems interact among each other in terms of matter and energy? This National Geographic article gives us an overview.
How did you observe this in Our Planet series?
There is so much to learn and discover about planet earth, whether on earth and even inside! What is inside the earth?

The earth’s interior is made up of several layers – the crust, mantle and core.
The earth’s interior is made up of several layers – the crust, mantle and core.
See how they look like here in National Geographic’s interactive graphics:
If you were to compare the layers of an earth to a hardboiled egg, what would be represented by the different “layers” of the cooked egg?
Has any man ever entered the inside of the earth? How far have we gone deep down? Check out this Deepsea challenge of National Geographic.

Explore further and apply to real-life situations what you have learned so far. Choose any of the activities in the three simulation labs and play the games. Note that these will be used for the module assessment.
That's it for module 1 ! Scroll up again and check learning objectives. Are you able to reach the target outcomes?
