Organizations such as the Ohio Academy of Science sponsor programs to encourage junior and senior high school students to conduct science projects. These programs are designed to give students who might pursue careers in technical areas a realistic foretaste of some of their future professional responsibilities, including the effective communication of technical information. This guide has been prepared to help students learn about technical proposals and to assist them in preparing proposals for research grants which are made available by the American Association for the Advancement of Science and other sponsors through the Ohio Academy of Science. The guide is divided into three major parts. The first part discusses the nature of a technical proposal. The second part discusses the content of a student proposal. Proposal content includes: objective(s); background information; description of experimental work; significance of anticipated work; and itemized budget. The third part presents a sample format for a proposal and the transmittal letter which must accompany the proposal. (JN)
