Printable Archaeology Worksheet for 9-Year-Olds (4th Grade) — Artifact Classification, Stratigraphy & Dig Mapping

Instructions

Welcome back, Junior Archaeologist! In our last mission, you learned how to analyze artifacts and understand soil layers (stratigraphy). Now, we need to record exactly where our discoveries are made. A dig site is like a giant puzzle, and knowing where each piece fits is the key to solving it. Let's learn how to map a site like a pro!

1. Start with the Review Questions in Part 1 to refresh your memory.
2. In Part 2, you will learn about the most important mapping tool: The Archaeologist's Grid.
3. Use your new skills in Part 3 to Plot the Finds from a Roman villa dig site.
4. In Part 4, you will Analyze the Map you created to uncover the story of the site.
5. Finally, tackle the Expert Challenge to solve a tricky puzzle combining all your skills!

Part 1: Review Your Field Notes

Building on what we learned last time, let's start with a quick review.

1. The Importance of Context

In our last worksheet, we learned that "context" is the location where an artifact is found, including the soil layer and other objects nearby. Why is knowing an artifact's context so important for an archaeologist?

2. Stratigraphy Puzzle

You are digging and find a metal buckle from a modern backpack in a soil layer above a layer containing a handmade clay bead. Which artifact is older, and how do you know?

Part 2: The Archaeologist's Grid

To record an artifact's context perfectly, archaeologists use a grid system. They divide the entire dig site into squares of the same size, giving each square a unique name, or "coordinate." This records an artifact's exact location, which is called its provenience.

It works just like the game Battleship! You use the letter for the column and the number for the row to find any square.

Example: An artifact found at coordinate B3 would be in the square where Column B and Row 3 cross.

Part 3: Plotting the Finds

Your team is excavating the ruins of an ancient Roman villa! Below is a list of important artifacts you've found. Your job is to map their provenience by drawing a small symbol for each one on the empty grid below.

Artifact List & Symbols:

• Two Roman Coins (C): Found at A2 and D4
• Broken Pottery Shard (P): Found at C1
• Iron Nail (N): Found at B3
• Charcoal pieces (a sign of fire): Found at C2
• A Wall Foundation (draw a thick line): Spanning from the bottom of B1 to the bottom of D1

The Dig Site Grid

Part 4: Reading the Map

Now that you have mapped the site, use your grid to answer these questions about the Roman villa.

1. Making a Connection

Look at where the pottery shard (P) and the charcoal (charred wood) were found. What do you think might have been the purpose of this area of the villa (around C1 and C2)?

2. Interpreting a Feature

Remember from our last lesson that a "feature" is a human-made structure that can't be moved. You mapped a Wall Foundation in row 1. What does the location of this wall tell you about the layout of the villa?

Part 5: Expert Archaeologist Challenge

Here's a puzzle that combines everything you've learned! During the dig, your team finds a modern plastic bottle cap in square A4. The confusing part is that it was found in the same deep soil layer as the ancient Roman artifacts.

Using what you know about stratigraphy, site disturbances, and grid mapping, give one possible reason why a modern object was found so deep in that specific spot.

Hint: Think about what might have happened only in square A4.

Answer Key

Part 1: Review Your Field Notes

1. Context tells the artifact's story. It shows how old it is (by its layer), what other objects it was used with, and its relationship to features like walls or pits.
2. The handmade clay bead is older. According to the principle of stratigraphy, deeper layers are older, and the bead was in a layer below the modern buckle.

Part 3: Plotting the Finds

Your grid should look like this:

Part 4: Reading the Map

1. This area was likely a kitchen or a hearth (fireplace). Finding charcoal (from a fire) near pottery (used for cooking or storing food) suggests cooking activities happened there.
2. The wall separates the top part of the site (row 1) from the rest. This shows us where one of the rooms in the villa ended, helping us understand the building's floor plan.

Part 5: Expert Archaeologist Challenge

(Accept any logical answer that specifies a disturbance in that one square. Examples below.)

• An animal (like a gopher or rabbit) could have dug a burrow right through square A4, pulling the modern bottle cap down from the surface into the older layer.
• A long time after the Romans left, someone might have dug a single hole in that spot to place a fence post, mixing the soil layers only in square A4.
• The roots of a large tree could have grown down through that specific spot, disturbing the layers and shifting artifacts around.
