The Archaeological Institute of America (AIA) wants to help K12 educators bring the fascinating subject of archaeology into their classrooms as a springboard for teaching scientific methods, critical thinking and writing, and analytical skills across the curriculum. Our Lesson Plans (www.archaeological.org/education) include several classroom excavation projects: Layer Cake Archaeology, Transparent Shoebox Dig, Shoebox Dig, Schoolyard Dig, and the Mystery Cemetery Project. Through simulated excavations, students solve puzzles, have fun, and learn skills that apply to many disciplines. The Lesson Plans (available as free pdf downloads) provide teachers with templates to follow or adapt, including detailed instructions, pitfalls to watch for, bibliographies, student handouts, and grading rubrics, as relevant. Our cake and shoebox digs are aimed at elementary grades, mostly K-3, but can be adapted for later elementary grades through Middle School. The Schoolyard dig is suitable for high-school students. The Mystery Cemetery Project is adaptable for ages 10 to 110, but teachers must use their own discretion and knowledge of their students, since the excavation and analysis of burials is a culturally sensitive issue.
