Elaborations

• evaluating various methods for investigating the ancient past, for example stratigraphy to date discoveries; DNA testing to identify past individuals from their remains (such as Egyptian mummies) as well as common diseases
• using a cross-sectional drawing of the earth’s surface from an archaeological excavation to identify the evidence located at various layers (stratigraphy) and what it reveals about change over time (for example a charcoal layer containing human remains and weapons may indicate the capture and destruction of an ancient settlement such as Troy)
