1. Warm up

5. Paths of Diffusion: 4000BC

6. Paths of Diffusion: 1000BC

7. Paths of Diffusion: 400AD

8. Paths of Diffusion: 1500AD

9. Assignment You will be tracking the spread of 6 critical innovations.
On one map: the spread of farming
On the other map:
Wheel
Writing
Sailing
Compass
Gunpowder

10. Wrap up Make a 3-column chart:
Places highly benefitted by diffusion
Places somewhat benefitted
Places not much benefitted by diffusion
List regions of the world by how well you think they have been benefitted.
