The Best Computer Science Competitions for High Schoolers

Microsoft runs the competition, and each year, students around the world compete in it. Students work in teams of up to three members to design a tech solution to a social or health problem.

Qualification: Student must be 16 or older.

Prizes: Each winning team is awarded $100,000.

Students work in teams of at least 10 along with 2 adult mentors to design and build an industrial-sized robot. They then must program the robot to compete in a sophisticated field game at competitions. Annual team registration fees are usually about $5,000.

Qualification: High school students in the U.S.,

Prizes: Various scholarships and cash prizes for top scorers.

It is designed to get more girls worldwide interested in coding and computer science. Girls work in teams of 1-5 and with volunteer mentors to use technology to design an app that helps solve real world problems such as climate change and hunger.

Qualification: Must identify as female and be between 10 and 18 years old.

Prizes: Prizes and scholarships up to $2,000.

To compete, your school has to have registered and paid the registration fee. Before the competition, the coach teaches coding with a focus on ACSL exam categories. Then, students work in teams of 3 or 5 students to complete four tests. Students can code in Python 3, Java 8, or C++ as defined on the programming platform.

Artificial intelligence (AI) plays an important role in the Asian Games Hangzhou 2022 and Asian Para Games. These terms might sound familiar, but how smart are they when applied to the 56 Asian Games venues (场地)?

Their smartness can be found in running the venues with less human labor forces. At the Huanglong Sports Center, a system called Smart Stadium Brain is built. A 25 square meter high definition screen lays in the venue’s information center, which guarantees a friendly environment for the athletes and audiences. A small screen on each seat is designed to be at the audience’s service. By finger touching, the audience can control it conveniently to watch and keep contact with the event. What’s more, supported by the 5G technology.

AI also means further protection on environment. At the Fuyang sports Center, although it has been raining for days, the roof of the venue still remains dry. And the secret lies in its attractive sky garden. The garden, is not only eye-catching but also useful. It allows the greening rate of the entire stadium to reach as high as 45%, being energy-saving. Under the cobblestones (鹅卵石), a recovery system is filtering (过滤) and collecting rainwater for the venue’s water system, and irrigation water.
