[G04-P07] Creating 3D model of reticulite for teaching materials with DSLR camera and utilization
Keywords:3D model, Creating teaching materials, Volcanic ejecta, education about cooperation between schools and museums, Utilization of ICT
1,Background and Aim
Junior high school Curriculum guidelines (notice Heisei29), science part “Chapter 3 creation of lesson plan and handling of content” says that “in order to raise qualities and ability,it is necessary to foresee the annual lesson plan. Plus, observation time, experiment time and to ensure time for students to explore on their own to solve problems.”
When students observe specimen,It is important real things. But,Kawano et al.(2020) says that there is some problem when students observe real thing.For example,It is difficult to give specimen for all students.
Recently, Almost students have smartdevice for education. School is doing observation study to use 3D model. It is complement the shortcoming of observation with real things, and assist study planning. Plus,Become a helping tool creating lesson design.
3D model is made by Photogrammetry. But, It is not done to make 3D model with specimens whose feature points are difficult to capture.
This research’s aim is to suggest that effective lesson for students with 3D model and to make 3D model with specimens whose feature points are difficult to capture.
2, Subject to learning content and 3D model
learning content is ｢Part 3 spout fire from ground, 1 eruption of volcano｣ at Japanese science textbook ｢Keirinkan mirai e hirogaru science 1｣
Reticulite specimen taken from Kilauea volcano, Hawaii Island is used in this study.(Fig2)
It is one of the volcanic ejecta and easy to understand extremely foamed structure that is formed through eruption.
3,Research method
I used specimen of reticulite.Plus,I used DSLR camera,remote control shutter,tripod,prime lens,polarized light filter,LED light stick,esk light and stand to put specimen.
Photographing process,
1,Put specimen and cardboard on stand to put specimen and the swivel chair.
2,Rotate a bit right after took a photo. Repeated it until 360-degree turn.
On the way, I put specimen directly on the swivel chair. Others, I use tripod,prime lens and background.F value was set 16 or 20.
Next,Making process of 3D model.1,Import photofrom camera to the ｢Photoscan(application)｣ 2,Aligning photo.3, Building dense point cloud 4,Building mesh 5, Building model texture 6, Exporting 3D model.
4,Result
I could reproduce foamed structure of reticulite(Fig2).Be able to make 3D model with specimens, in spite of feature points are difficult to capture. You can view this URL(https://sketchfab.com/3d-models/reticulite-76ef6426eda84fee8fde31cce3a073c8)
5,Issue and Discussion
First, I suggest that lesson with 3D model.Field is Mechanism of eruption.This exist on ｢Part 3 spout fire from ground, 1 eruption of volcano｣ at Japanese science textbook ｢Keirinkan mirai e hirogaru science 1｣.
Lesson process
1, Check ｢what is magma｣ .
2, Present this study’s aim ｢How does volcano erupt?｣ .
3,Wathing 3D model and talk about noticed point.
4,Wathing a video of carbonated drinks foam and spout.
5, Discussing and expressing about mechanism of eruption.At that time,make team or walk around.
6,Share opinion with students.
7,Check ｢The eruption is buoyant as the magma fizzles and its density decreases. The magma then rises and fires｣.
I want to achieve proactive, interactive, and authentic learning, and to raise qualities and ability to explore scientifically.
Second,It is necessary to devise a light or background,to change the lens to a zoom lens and to change the specimen to a big specimen.
