Reason about toolmaking across six materials and four cultures with archaeological inference
Examine and reason about tools made from STONE, BONE, FIBER, CLAY, BRONZE, and IRON across the four studied cultures. Apply archaeological reasoning: what materials were available, what skills were needed, what the tool tells us about the maker's place and time. Vocabulary: knap, coil, forge, cordage, smelt, alloy, archaeological inference.

Prereqs
Common misconceptions
- 'Older tools are worse than newer tools' - the unit refutes this by showing that contemporary cultures still use stone, bone, fiber, clay tools alongside metal, and that material choice reflects available resources and cultural priorities.
- 'Iron is universally better than stone' - the unit teaches that the right material depends on the job; obsidian blades are sharper than steel, fiber cordage is lighter than metal cable.
