Instructions
- Read through each section of this Field Mission Debrief carefully. You are the lead archaeologist!
- Answer the questions to the best of your ability, using what you've learned about archaeology.
- Use a pencil so you can easily make changes to your findings.
- When you are finished, you can check your work with the Answer Key at the end.
Part 1: The Archaeologist's Toolkit
An archaeologist is only as good as their tools! Match each tool to its correct job by drawing a line from the tool to its description.

Part 2: Decoding the Discoveries
You are excavating a site and uncover several interesting items. Read the scenario and answer the questions that follow.
1. What is the scientific term for human-made objects from the past, like the clay pots?
________________________________________________________________________
2. Why is finding these items *together* so important for an archaeologist? (Circle the best answer)
- It means they are all the same color.
- It tells a story about how people might have lived (cooking, storing food, eating).
- It means they were buried by the same person on the same day.
3. Based on the clues (clay pots, animal bones with cut marks, burnt seeds), what is one activity that might have happened here?

Part 3: Reading the Layers of Time
Archaeologists study soil layers, called strata, to understand time. The Law of Superposition states that deeper layers are older than the layers above them. Look at the description of the dig site below.
Top Layer (Layer A): Loose brown soil with a glass bottle and a coin from 1985.
Middle Layer (Layer B): Compact, dark soil with a broken piece of a ceramic plate and a rusty iron nail.
Bottom Layer (Layer C): Sandy soil with a carved stone arrowhead.
1. Which artifact is the OLDEST?

2. How do you know it is the oldest?

3. What is one artifact you would be most excited to discover on a real dig? Draw it below and write a sentence describing what it is.

Part 4: Expert Archaeologist Challenge (Optional)
Imagine you are digging in what you believe is an ancient campsite. In a deep layer of soil, you find a beautifully crafted stone spear point right next to a modern plastic soda bottle cap. What does finding these two items together probably mean? What problem does this create for you as an archaeologist?

Answer Key
Part 1: The Archaeologist's Toolkit
- 1. Trowel → C. A small shovel used to carefully scrape away layers of soil.
- 2. Soft Brush → A. Used to gently clean dirt off a delicate artifact without damaging it.
- 3. Sieve (or Screen) → D. A screen used to sift dirt, helping to find very small artifacts like beads or seeds.
- 4. GPS Unit → B. Used to record the exact location (coordinates) of the dig site and any artifacts found.
Part 2: Decoding the Discoveries
- Artifacts
- B. It tells a story about how people might have lived (cooking, storing food, eating).
- (Answers may vary, but should be logical) Possible answers: Cooking a meal, preparing food, having a feast, storing grains.
Part 3: Reading the Layers of Time
- The stone arrowhead.
- Because it was found in the deepest/bottom layer (Layer C), and deeper layers are older.
- (Answers will vary based on student's drawing and description).
Part 4: Expert Archaeologist Challenge
- What it means: This probably means the site has been disturbed. An animal may have burrowed a hole, a tree root grew through the layers, or a person may have dug there recently, pushing the modern trash (bottle cap) down into an older layer.
- The problem it creates: The context is now unreliable. You can no longer be certain that everything in that layer is from the same time period. It makes it much harder to accurately tell the story of the site.
