In Mudan Township, Pingtung County’s Tungyuan Village, sits a prairie as far as the eyes can see. This paradise is a vast wetland, and a favorite for many ecologists. Year-round, the grass is green and grows knee high, offering a very rich wetland ecosystem.Walking in the swamp grasslands, one can feel that its water under the grass, yet it’s like walking in a prairie that shakes and gradually sinks.It feels like walking on a matress.How did this large grassland on water form?Why won’t people walking on it fall in?
The “921” Earthquake is the most devestating earthquake in the last hundred years. The Sediq who live in the Nantou area also experienced a great earthquake in the past. This earthquake not only changed the landscape, but also affected the fate of the Sediq.
This episode introduces the three seismic belts: the Pacific Ring of Fire, Eurasia seismic zone, mid-ocean ridge seismic belt. Using toasts and soup to show the collisions of crustal plates, kids can better understand earthquakes and learn to protect themselves.
The Tao of Lanyu know that water is essential, therefore, they treat the development of every terraced field with the utmost respect. Therefore, we find a very smart tool in each of the fields, a barrel. What role does it play in a field? Through the students observation, we find out the differences between the Yeheng fields and Lanyu’s fields.
Our stay in beautiful Lanyu continues. We check out another Tao artifact: the underground house. As the place faced with the most typhoons in the world, Lanyu is a harsh place for buildings. However, the wise ancestors of the Tao people passed down the secrets of the underground house. Based on the science of air pressure, these houses have saved lives for many generations.
This episode introduces the Atayal’s natural resources, the hot springs of Wulai. The formation of the hot spring is closely related to volcanoes. During volcanic eruptions, a volcano would often emit magma. However, sometimes, some magma would remain close to the surface. These underground magma would slowly release heat into the ground to heat the water above. In some regions without volcanoes, magma remains active and hot springs can still be formed.
By learning about pressure and boiling eggs, the kids realize how pressure can affect the flow of water and turn groundwater into hot springs.
The flint is a necessity for the early Amis when they go into the wild. The expert of this episode picks stones off the ground and produces sparks. To understand the scientific principles of a flint, the science teacher helps kids understand the characteristics of a quartz. By understanding the structure of a quartz crystal as well as how electrons are released, the kids know that when a quartz is beaten against iron, high temperature is released instantaneously, releasing electrons and sparks.
