“Computer science empowers students to create the world of tomorrow.”
– Satya Nadella, Microsoft CEO
What is Hour of Code?
The Hour of Code™ is a global movement introducing tens of millions of students worldwide to computer science, inspiring kids to learn more, breaking stereotypes, and leaving them feeling empowered. The Hour of Code began as a one-hour coding challenge to give students a fun first introduction to computer science and has become a global learning event, celebration, and awareness event.
Why computer science?
Computer science is foundational and is changing every industry on the planet. Every 21st-century student should have the opportunity to learn how to create technology. Computer science concepts also help nurture creativity and problem-solving skills to prepare students for any future career.
Economic Opportunity for All
Computing occupations are the fastest-growing, best paying, and now the largest sector of all new wages in the US. Every child deserves the opportunity to succeed.
Students love it!
Recent surveys show that among classes students “like a lot,” computer science and engineering rank near the top—only performing arts, art, and design are higher.
Ready to participate with your class?
We’ve created two free coding activities utilizing Scratch to help you and your students participate in Hour of Code this year. Scratch offers colorful and modularized drag-and-drop graphical blocks that make it easy for programmers to code.
Hour of Code Activity for Entry Level Coders
In this activity students program a catch game where they can make choices on graphics and game options. The free Scratch software works on your web-connected device.
The Catch Game can also be completed by any classroom with no sensors needed.
Hour of Code Activity for Advanced Coders
For more advanced coders, this activity combines Scratch-based coding and exploration of the ideal gas laws. Students can change multiple variables and observe changes. Results can be compared with their calculations.
The ‘Hour of Code™’ is a nationwide initiative by Computer Science Education Week [csedweek.org] and Code.org [code.org] to introduce millions of students to one hour of computer science and computer programming.
