好玩科學
今集,小朋友將探討家居隔音、圖釘床分散受力及火箭氣壓推進的原理,並挑戰經典變牌魔術。他們亦會透過拔河研究摩擦力與張力,利用交叉輪廓線創造立體錯覺,最後更會介紹月球資源開採及仿生四肢的肌電義肢應用。
The kids explore experiments in; sound-proofing that can be done at home; how spreading force over several points works in a bed of nails; rocket design and its effect on drag and stability, how air pressure can be used for propulsion; the classic Erdnase Change card trick, the conflict between friction force and tension force in a game of tug-of-war; and using cross contour lines to create the illusion of dimension. Future fun facts look at what resources we might one day mine from the moon, and how myoelectric prosthesis is being used in bionic limbs.
