Title: Plasmas the First State Of Matter

Abstract: A plasma is not only the most prevalent state of matter in the universe, it is the first state of matter from which evolved the other three states. The universality of plasmas has however not made it any easier to understand them. Astrophysicists consider plasmas, at best, an unavoidable presence and reluctantly accept them, often without the plasma phenomena. I shall strive to introduce the youngsters to the phenomenal diversity of plasmas in the cosmos and in our day to day lives. Plasmas can be described as a collection of electrically charged particles or as conducting fluids. Different levels of description of a plasma come handy to delineate the characteristics of an object, from its shape to the radiation it emits. The stability or otherwise of a plasma is the main preoccupation of a practitioner. Unstable plasmas are not always undesirable. Plasma come with different degrees of ionization. I shall also emphasize some of the novelties of a partially ionized plasma.
