[G04-04] Using drone videos to teach earth and environmental science
Keywords:drone videos, teaching materials, visualization, 3D model
Introduction:
As an earth science teacher, I consider space and time to be important concepts for students to intuitively understand. They form the base for learning geoscience (earth and environmental science). Unfortunately, since I teach geoscience at a night-time high school, there is no opportunity for students to do field observations during class to see these concepts for themselves.
To make up for this, I tried recording some videos using a drone to give students a better understanding of the space around them. These videos make teaching difficult concepts, like geology and rock formations, easier to understand for students.
Drone and Software:
I used the Parrot ANAFI series drone and the Pix4DCapture software to record videos of the surrounding areas, using both normal and thermal vision. I also used the Pix4DMapper software to create 3D models of the land.
The following are videos that I have taken:
1) Hiki-Iwagun Rock (Tanabe, Wakayama): This place is made of sloped sandstone, which has eroded into a shape that looks like several frogs. There is a hiking path through the area and you can touch the rock formations. But, looking from above using a drone, you can truly see the different rock layers and the shape of the erosion.
2) Phoenix Fold (Susami, Wakayama): You can clearly observe the zig-zag folds on the sea cliffs here. However, for safety reasons, it is difficult to get a good look without a guide. Using a done, though, you can clearly and safely see the many rock layers that make up the sea cliffs.
3) Wabuka Coast (Kushimoto, Wakayama): The sea cliffs here are made from alternating layers of sand and clay. In the nearby reef, you can see how the ocean has unevenly eroded the rocks depending on their composition. You can also observe the continuous incline of erosion from the reef to the sea cliffs.
4) Hashigui-Iwa Rock (Kushimoto, Wakayama): Here is a dike formed by the activity of the Kumano Caldera. There are large rocks in the area moved here by a tsunami. From the viewpoint of a drone, you can see the outline of the dike and recognize the path that the magma took after erupting through the surface.
5) Shimasato-Ohama Beach (Nachikatsuura, Wakayama): At the mouth of the river, you can see the formation of a sand bank made by the coastal waves. Using a drone to make a 3D model covering hundreds of meters, you can understand the shape of the whole area. You can also view how the large waves caused by strong winds have carried the sand towards the land.
6) Tama-no-Ura Beach (Nachikatsuura, Wakayama): It is an inner bay on the Pacific Ocean. The sea water is clear and there is eelgrass growing on the ocean floor. Taking pictures from above, it is possible to view the vast field of eelgrass.
Next Time:
Of course, nothing is better for teaching students than field observations. To make up for this, it is necessary to listen to student feedback. I wish to use this feedback to make more visual and intuitive videos.
