Presents basic physical theory for movement of electric charges in clouds, earth, and air during production of lightning and thunder. Amount of electrical energy produced and heating effects during typical thunderstorms is described. Generalized safety practices are given. (JM)

Focuses on the main naturally occurring ways in which compounds of carbon, nitrogen, and sulphur enter or leave the atmosphere. (Author/SA)

Tells how science books can provide children with a chance to learn the methods of science and how to use them. (HOD)

This article developed from a survey of the five most popular biology texts which promote the theory of invariant homeostasis rather than biological rhythms. The popular fad of "birthdate biorhythms" is discussed in relation to providing education on biological rhythms and its legitimacy to the public. (SA)
