11 teachers took part in a half day of challenging classroom work at ASIAA's Teacher workshop on May 20, 2023. It was the second Black Hole Classroom Activities Workshop organized by the EPO for high school teachers. This time it took place in Kaohsiung, at the National Sun Yat-sen University.

Activity 1 Escape Speed and Black Holes
Activity 1 Escape Speed and Black Holes
How were black holes first described using Newtonian gravity? Lets begin the activities by giving the "Escape Speed" some experiments! A session hosted by Dr. Mei-Yin Chou
19世紀的科學家對黑洞的想像是什麼？從牛頓物理的「逃離速度」開始回顧這段科學發現的歷程吧！

Activity 2 General Relativity and Black Holes
Activity 2 General Relativity and Black Holes
The fabric used to model one part of the theory—the curvature of space. Instead of pulling down, we popped it up here to remove the confusion comes from Newtonian's gravity. Session hosted by Dr. Mei-Yin Chou
試試把狹義相對論可視化 -- 換個方向模擬時空變形

Happy faces of the teachers! They were testing the spacetime warping experiment. Within minutes they have invented new game - throwing the marbles, of course! - and entertained themselves.
彈性布讓老師們童心大作，脫離原本教案，玩起了互丟彈珠的遊戲。

Activity 3 Imaging the M87*
Activity 3 Imaging the M87*
Finally, we simulated what is so challenging about Imaging the Black Holes -- with a flash and two pencils, in a dark room!
Two pencils form a gap, and to viewing the flash through the bottom of the gap, observer will see blurry image. By moving upward to where the gap is wider, image will be better. Then the participants will do simple math to determine how big a telescope is needed to view those black holes which are of small angular sizes.
從史上第一張黑洞成像可以看到那些關鍵重點？原來不可不知重點是角大小，因為黑洞小到只有"一億分之一度"，相對的，望遠鏡要是不夠大，你看到的不會是一個甜甜圈，不信來試試！
For those who with very poor eyesight, Lauren shared her pre-recorded videos to support the participants learning from this simple experiment.
鑒於不少高度近視者無法完成本項活動，黃珞文將實驗工具加以改良並將過程以預錄影片向學員解說，有影片有解答！
