Guidelines for Participation

What to Submit?

Submit one PDF document explaining your science or technology idea, model or concept. Your document should include:

  • Project Title
  • Student Details: Name(s), class and school
  • Problem or Idea: What are you trying to solve, improve or explore? How It Works: Explain the main concept or working process in simple words
  • Visuals (if available): Photos, sketches or diagrams to help explain your idea
  • Real-Life Use: How could your idea be useful in everyday life or the future?

Important Guidelines

  • Your submission must be your own original work.
  • Use clear, simple language. Focus on the idea, creativity and explanation rather than fancy presentation.
  • A working prototype is not compulsory at Level 1; a clearly explained concept is acceptable.
  • Visuals (if available): Photos, sketches or diagrams to help explain your idea
  • For team entries, include the names and details of all team members. Teams may have up to 4 students.
  • Check that your document is complete, readable and saved as a PDF before submitting.
  • Incomplete, copied or duplicate entries may be disqualified.
