An interdisciplinary approach to redefine problems outside of normal boundaries and reach solutions. The learners of IGYR1 performed an experiment on expansion of solids (Metal bob and ring) and comparison of expansion of different liquids for same change in temperature. The yellow flame and the black powder deposition on the metal bob while heating and the expansion of different liquids based on force of attraction between molecules and specific heat capacity were analysed viz., Physics and Chemistry of materials.
