Mini Lesson

A tech fair is your opportunity to showcase everything you have learned and created this year. You will present your AI project to family, friends, and visitors — explaining the problem your project addresses, the AI technology you used, and what you learned through the process. This is also a moment to reflect on your growth as a digital learner.

Preparing Your Tech Fair Presentation

  1. Know your topic — be able to explain your project clearly without notes.
  2. Practice your opening — start with a strong hook: a question, a surprising fact, or a brief story.
  3. Use visuals — posters, slides, or a live demonstration make your project more engaging.
  4. Anticipate questions — think of questions visitors might ask and prepare your answers.
  5. Speak slowly and clearly — eye contact and confident body language show you believe in your work.
