The oldest methods used for separation and purification include settling down of impurities and filtering them out to obtain the pure product components. Separation of substances from a mixture requires specific techniques for different sizes and types of substances. This module talks about two important separation techniques like sedimentation and filtration. Sedimentation uses the principle where the particles are not soluble in the solvent and hence settle in the bottom of the mixture separating the two components. Filtration uses the principle of selective separation where the particle...

Modern technologies have allowed us to harness the world’s available water for energy and industrial purposes, but these technologies have failed us in finding a solution to the ever increasing industrial water scarcity. This module has found a way to help millions of global citizens who are facing challenges due to scarcity of water and support the UN Water Program and other international agencies working on water and sanitation issues.

Borrowing from one of nature's most water-...

The module seeks that K-12 students understand in a fun way the concepts related to surfactant compounds as well as the importance of protein denaturation and its relationship to achieving the snow point when whisking egg white.

This module, backed with a sense of inquisitiveness, aims towards educating the young peers about the principle behind skin friction which is basically friction between the surfaces of objects. This very simple material science principle stands behind the deep pile foundations used to support structures built on sand such as the giant floating building - Arabian Tower/ Burj Al Arab standing on sand which uses the frictional resistance between soil and a structure or between soil and a pile being driven in it or why competitive swimmers wear swimsuits and swim caps or shave their heads for...

The module is emphasized to give the students knowledge about super absorber polymer (SAP) and their action towards different liquids. The module is prepared to check whether the super absorber shows its action just like it does in the case of water.
