 Universalizing Science and Technology literacy Scientific and technological literacy, in its broadest sense, means much more than simply being able to read, understand and write about science and technology, however important these are.  STL also includes the ability to apply scientific and technological concepts and process skills to the life, work and culture of … Read more Universalizing Science And Technology Literacy (2)

 Molecules Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. The division of a sample of a substance into progressively smaller parts produces no change in either its composition or its chemical properties … Read more Molecules

 Engineering plastics Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene).  Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such … Read more Engineering Plastics

 Working principle and use of generator   Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction. The faradays law states that whenever a conductor is placed in a varying magnetic field, EMF is induced and this induced EMF is equal … Read more Generator

 Biotechnology in agriculture For about 10,000 years , farmers have been improving wild plants and animals through the selection and breeding of desirable characteristics. This breeding has resulted in the domesticated plants and animals that are commonly used in crop and livestock agriculture. In the twentieth century, breeding became more sophisticated, as the … Read more Biotechnology In Agriculture

 Total internal reflection Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. In general, total … Read more Total Internal Reflection
