Better understanding of an area of science is the least that we can gain from doing a science project. At their best, science projects foster habits of effective planning, attention to detail, careful work, and high performance standards that will serve us well throughout our lives. Moreover, there is always the promise that the project will open the door to a satisfying career. Project Exhibits More and more, scientists are called upon to share their work not only with other scientists but also with legislators, administrators, sociologists, artists—all kinds of people in all kinds of professions. To follow this lead, student scientists also must tell other people about their science projects. When executed properly, exhibits are an effective way to do this. Exhibits which combine interesting visual materials with well-written messages can communicate much in very limited time and space. Good exhibits can speak clearly to a great variety of viewers. Those already generally familiar with the subject may absorb the entire message, but even the uninitiated will find something of interest. Science Fairs Fairs have been popular throughout history. Generally they have been occasions to display work or feats of which people are proud. Often they have stimulated progress and the exchange of goods and ideas. Early in this century some teachers encouraged their students to undertake individual science projects, then exhibit them before their classmates and fellow students. Between the two World Wars some individual school systems developed citywide science fairs to show the most outstanding of these exhibits from each school. The science fair movement gained momentum rapidly after World War II, and in 1950 the First National Science Fair was held in Philadelphia, drawing exhibitors from 13 affiliated area fairs. Today the national event draws exhibitors from more than 200 affiliated state and regional fairs. Recent entry of competitors from several other countries has produced its new title—National Science Fair-International (NSFI). It is the “Olympic Games” for science fair exhibitors, conducted by Science Clubs of America, an activity of Science Service, 1719 N Street N. W., Washington, D. C.

S. student to achieve Atomic Energy Commission Special Awards recognition. He was one of 10 alternates to the 10 winners and is shown receiving a Certificate of Achievement from Harry S.
