A Fault-y Setup

Are you a Grade 8 science teacher? Do you need help in teaching Earth and Space topics? If you do, then you’ve come to the right place. We have a short video on earthquakes and faults—and a guide to go with it—to help you in your classroom lessons.

Video Guide for A Fault-y Setup

The video is for Grade 8 teachers who will be teaching about Earth and Space topics in the K to 12 Science Curriculum. In particular, the video is about A Fault-y Setup, the first activity in Module 1 (Earthquakes and Faults) of Unit 2. The video will answer two questions: What is a fault? and What is the relationship between faults and earthquakes?

First, the video will show how the activity is performed in class. The students are supposed to see two things. As the cardboard sheets are moved: 1) a “break” will form in the sand; and 2) the lines that are drawn to simulate a “road” will be displaced. The “break” in the sand is supposed to imitate a fault. (See photo below.)

Next, the video will show a picture of a road with a fault cutting across it. (See photo above. The same photo is in the Learner’s Module provided by DepEd.) The teacher will ask the students to compare what they see in the picture and what they observed in the activity. The students are expected to say that there is a similar “break” that cuts across the road, and the road is displaced by it.

The teacher will then say that the “break” is called a fault. The students are then challenged to come up with a definition. Based on the activity and the picture, the students are expected to say that a fault is a break in the ground (or, in the Earth’s crust) along which significant movement has taken place. This takes care of the question, What is a fault?

Finally, the second question, What is the relationship between faults and earthquakes? is answered: sudden movements along a fault produce earthquakes. Now, how does this “sudden movement” take place? This will be tackled in another video. Watch out for it!
