- Focus on innovation, not cost.
- Use waste materials creatively.
- Explain how your model helps society or environment.
🧠 What Judges Will Look For
- Originality
- Creativity
- Scientific principles
- Practical usefulness
- Neatness and working
- Presentation and explanation
📘 1. Guidelines for Organising a One-Day Seminar
A seminar is a short event where students and teachers discuss ideas related to science, maths, and technology.
🎯 Purpose of the Seminar
- To help students understand the theme of the exhibition.
- To share new scientific ideas.
- To allow participants to ask questions and learn from experts.
📝 How to Organise It (Simple Steps)
- Decide a date and venue (school hall, auditorium, or online).
- Invite resource persons (teachers, scientists, engineers).
- Prepare a schedule:
- Welcome speech
- Talk by experts
- Student presentations
- Q&A session
- Display charts, models or videos related to the main theme.
- Encourage students to share their ideas freely.
- Collect feedback from students and teachers.
📘Criteria for Selection of Models (How Judges Choose)
Judges look for the following while selecting models for district, state, and national levels:
✔️ 1. Originality
- The idea should be new, creative, and not copied.
✔️ 2. Scientific/Mathematical Understanding
- You must understand and explain the principles behind your model.
✔️ 3. Practical Usefulness
- The model should help solve a real-life problem.
✔️ 4. Working Condition
- A working model is better than a simple chart or dummy model.
✔️ 5. Neatness and Craftsmanship
- Your model must look clean, strong, and well-made.
✔️ 6. Use of Low-Cost and Waste Materials
