3. The Stone Age The period of time when the first humans lived.
This period is called the STONE AGE because it is the time when the first humans began to use TOOLS made of stone.

The use of tools shows the development of the human brain

4. Types of Stone Tools
Early “Choppers” were made by striking stones together to make sharp edges with one side that was uncut that could be used as a handle. These were used to process food; cut, scrape, chop.
The “Hand Ax” came later and was an improved chopper with a much sharper blade shape. These tools had more uses like chopping tree limbs and digging holes.
The “Flint Knife” was a stone blade like the hand ax but attached to an antler or a piece of wood. These could be used in hunting. These were also modified into “Spears”.

As Humans developed, they began to bond together to form these.
Each of these groups then began to develop there own language, religion, art, Etc.
