That was a cute little bear. Oh... They come on style! Riding up and down to the big town Taking away to the dark side I wanna be your last and last In the forest, with the night silence and the light of the wild animals Crush was surprised to see a giant rock lying on the ground. Wow, this is so cool and cool! Suddenly, an old, smart owl, named Hagrid, jumped down from a nearby tree, causing the rabbit, Crush, to run into the nearby tree to hide. That's right, Crush, a shining rock, do you know what's special about it? Hearing the familiar call, Crush jumped out of the tree. Hello, Hagrid, I've just seen it shine, but I don't know what's so special about it. This is a grainy stone, a rock that doesn't shine naturally. Hello, Crush and Hagrid, I'm Irrender, a little star that loves to shine. Wow, Irrender shines so beautifully. Is Irrender a natural luminous material? That's right, Crush, Irrender is a star that emits light and energy from its luminous process. Hagrid, is this tree a natural luminous material? No, Crush, the tree is a natural luminous material. So, what is natural luminous? Can the students answer for me? Let's listen to Hagrid's answer. Natural luminous is the phenomenon of elements emanating from a luminous star, which is not caused by external forces. Natural luminous often has the ability to emit light to the outside environment. Ah, so that's what natural luminous is. There are many types of luminous emitted, but not due to the phenomenon of luminous, such as light, which can emit luminous in the form of heat and light, but not luminous. Oh, so that's what it is. In natural luminous, there are usually elements such as uranium, radium, thorium. Natural luminous elements often appear in many places, such as in rocks, soft rocks, air, or in water. Thank you, Mr. Hagrid. I understand more about natural luminous. The natural world is so magical and vast. Keep exploring and learning. Nature always has interesting things waiting for us.
