TYPICAL OPEN-ENDED EXPERIMENTS

Open-ended experiments are a type of laboratory activity where the outcome is not predetermined

and students are given the freedom to explore, design, and conduct the experiment based on the

problem statements as per the concepts defined by the course coordinator. It encourages creativity,

critical thinking, and inquiry-based learning.

1. Comparative study of flash point and fire point of various fuels / oils using the open cup

method

2. Comparative study of flash point and fire point of various fuels / oils using the closed cup

method

3. Comparative study on viscosity of different base fuels.

4. Investigation of the effect of additives on the viscosity of base fuels.

5. Selection and justification of appropriate joining techniques for given applications

6. Fabrication of a sheet metal part with simple geometry and soldering.
