This teaching unit for fourth to sixth grade history students outlines 20 activities aimed at developing an appreciation in students for a particular time in history. The knowledge goals state that students will gain an understanding of a time period or person in history and will infer how the time period or person influenced the future. The skill goals focus on learning how to present knowledge gained through research, and learning how to make predictions based on facts. Attitude goals seek to have students realize their own significance to our world, and develop an appreciation of history and its study. Behavioral objectives are keyed to each of the unit goals and activities. Activities include: building a time machine, "living" in a distant time period, "meeting" people out of history, creating "time portals" in areas of the classroom which represent different eras, viewing television shows and movies dealing with time travel, conducting library research, and making a time capsule. The unit evaluation is based on a point system and includes group as well as individual assessments. The bibliography lists names of five movies and television shows used, and three additional resources. (JDH)
