Digging stick – a pointed, wooden stick used to dig and pry edible roots from the ground.
Domestication – the process of taming or making usable for humans.

Pottery – Earthenware or clayware pots, dishes, or vases. These cups, bowls, and other dishes or objects were made from clay and hardened by heat.
Prehistory/Prehistoric – information about past events prior to the recording of events in writing. The period of prehistory differs around the world depending upon when written records became common in a region.
Projectile Point – the stone point attached to the end of darts, spears, and arrows. Often called "arrowheads".
Roasting Pit – a pit dug into the ground that was used for cooking. The pit contained fire-cracked rocks, charcoal, ash, and sometimes the remains of whatever was cooked.

Site – is a word used by archaeologists for places that prehistoric and historic people lived in or used. Sites are places where humans left things behind.
Stratigraphy – The science of studying layers of materials, as in rock layers in the Earth or deposits in archaeological sites. Cultural remains and dirt become buried over time and, usually, the layer on the bottom is the oldest, the layer on the top is the youngest. Dirt of different layers is often colored differently.
Tanning – the process which turns animal hides into leather.
