Computer Science

Computers are everywhere. They are used in applications as various as PCs, robots, entertainment devices and artificial intelligence. This project gives you a chance to learn about how computers and other information technologies work alone (software, mechatronics and coding), how computers work together (using WiFi, Local Area Networks, APIs and the Internet), computer literacy and safety, web design, VR/AR, mobile apps, computer graphics (CGI), music (mutli-media) and social media.

How can you showcase what you learned?

Computer projects cover a wide array of topics, but in each area, there are three divisions for Classic 4-H members: Beginner (Grades 3-5), Intermediate (Grades 6-8) and Advanced (Grades 9-12). 

What are the guidelines for showcasing/ exhibiting your project at the fair?
exhibit guidelines 
  • Cloverbud 4-H members: Exhibit a poster or notebook. Possible topics include: computer hardware, how and why to use a computer, where in the community you have seen computers used, what you have learned about code, or a favorite program or web site.  
  • Classic 4-H members: Updated for 2021

Note: Any software submitted MUST be compatible with PC and MAC. If any software beyond the MS Office Suite is needed, you must supply that software and comply with all manufacturer copyright laws. Any mobile apps must be Android or IOS compatible.    


  • Cloverbud 4-H members--no scorecard
