FAQs on Engaging Science Working Models: Boost Concepts & Creativity for CBSE 2025-26

1. What is the primary objective of creating a science working model for CBSE school-based assessments in 2025-26?

The main objective of a science working model is to demonstrate a student's ability to apply theoretical scientific principles to a practical, hands-on application. For CBSE assessments, examiners look for models that effectively visualise a complex concept, showcase analytical and problem-solving skills, and reflect a deep understanding of the chosen topic from the syllabus.

2. What are some important questions judges frequently ask about a working model during a science exhibition viva?

To score well in a science model viva, be prepared for these frequently asked questions:

What is the scientific principle behind your model?
What inspired you to choose this particular topic?
What were the main challenges you faced while building this model and how did you overcome them?
Can you explain the function of each major component?
What are the real-world applications or implications of your project?
What are the limitations of your model and how could it be improved in the future?

3. How can a student choose a topic for a science model that is likely to score high marks in a CBSE evaluation?

Choosing a high-scoring topic involves more than just picking something from a book. Focus on a topic that solves a real-world problem (e.g., water conservation, renewable energy) or demonstrates a complex syllabus concept in a simple way. Ensure the project is feasible with available resources and allows for a clear, demonstrable outcome. An innovative approach to a common topic often scores higher than a complex but poorly executed idea.

4. What safety precautions are considered an important parameter when evaluating a science working model?

Examiners consider safety a critical aspect of your project execution. Important precautions to mention and follow include:

Proper handling of sharp tools and materials under supervision.
Safe management of any electrical circuits, using low-voltage power sources and ensuring proper insulation.
Correct use and disposal of any chemicals, if applicable.
Ensuring the model is stable and has no hazardous moving parts exposed to the viewer.

Demonstrating awareness of these shows responsibility and thorough planning.

5. How should you explain the scientific principle behind your working model to secure full marks?

For a high-scoring explanation, first, state the principle clearly and concisely. Then, use your model to provide a step-by-step demonstration, pointing to specific parts and explaining their role in the process. Use simple analogies to connect the complex idea to something the examiner can easily understand. Conclude by summarising how your model successfully proves or illustrates that core scientific principle.

6. Beyond just working, what makes a science model 'innovative' from an examiner's viewpoint?

Innovation isn't just about a new discovery; it's about a novel approach. An examiner will see a model as innovative if it:

Uses sustainable or low-cost materials to achieve a sophisticated result.
Presents a well-known concept in a completely new and more effective way.
Integrates technology (like sensors or basic coding) to enhance the demonstration.
Offers a practical and creative solution to a common, relatable problem.

An innovative model shows original thinking, which is a key criterion for high marks.

7. What are the most common mistakes students make when presenting their science models that lead to lower marks?

Common mistakes that students should avoid for better scores include:

Inability to explain the core principle: Memorising a script but failing to answer follow-up questions.
A non-functional model: Not testing the model thoroughly right before the presentation.
Messy or incomplete presentation: A poorly labelled, untidy setup distracts from the quality of the work.
Not knowing the limitations: Being unable to discuss the project's weaknesses or potential areas for improvement shows a lack of critical thinking.

8. Why is maintaining a logbook or report an important component of a science working model project?

A logbook or project report is crucial as it serves as documented evidence of your entire project journey. It is highly valued by examiners as it shows your process, from initial brainstorming and research to design, testing, and troubleshooting. Important details to include are dated entries, diagrams, data collected, challenges faced, and how you solved them. It proves the work is original and demonstrates a systematic approach to scientific investigation.
