Homo: Half man half ape. Homos used stone tools for many things like hunting, building, and creating.
Hammer stone: A rock used to make flakes for tools. Homos used hammer stones to make tools
Flakes: Flakes are used for the tools they would be attached to a stick and then that tool would be called a flake tool.
Another thing I learned was how to make a stone and what it was used for.You made it by using a hammer stone (which is a rock) to make flakes from a different rock,The flake was connected to a stick by twine and then was used. when the tool is finished being made, it is used for hunting, building, and ect.
That is what I learned in my whole research.
