This 2-week unit uses visuals of a recent space walk as the basis for an introductory study of the nature of language. The aims of the unit are (1) to show pupils how language operates, (2) to stimulate awareness of the importance of basic language skills, (3) to develop an increased desire in using language effectively, and (4) to acquaint teacher and pupils with the needs, interests, and English abilities of the class. The first day's study begins with the writing of alternatives to Neil Armstrong's "Great leap for mankind" speech. This is followed by a study of the wording of the plaque left on the moon by the crew of Apollo 11 and culminated in role playing by students of the first American landing on Mars. In following lessons, students study the role of persona and audience in written composition, write their own reactions to space travel, and do exercises dealing with appropriateness in language usage.
