The STEM Study Contest Online Challenge is an online contest program based on the original program of the Xinghua International STEM Study Contest, in which four projects, namely  “Water Rocket”，“Wire Spinning Top”，“Trebuchet Attacking Fortress” and “Strongest Paper Bridge”, are selected to form a more adaptable and operational online challenge program. The event is aimed at middle and high school students from China and other countries along the Belt and Road. Contestants can choose any one challenge (or multiple challenges at the same time), complete the challenge by studying the project, and upload the challenge results to this website, where the online challenge section will be displayed according to the latest challenge results of each project as determined by the judges.
