The Science Activity Centre generates resource material for teachers, students and science enthusiasts that explains scientific concepts through do-it-yourself (DIY) hands-on activities. These include videos, sequential photographs and small booklets that describe the process of making toys/exhibits and also explain the scientific principle behind them. This digital repository has sections for various disciplines of sciences that are generally covered in primary and secondary school curriculum. This repository will be useful for teachers who want to make these models for their classroom teaching and for students and science enthusiasts who want to explore scientific concepts by performing small experiments.
