Intro Animation - Core/Periphery Theory

A quick animated intro video I created to give students a crash course on Core/Periphery Theory. From here the lecture will largely be inquiry based with tea...
Luke Walker's insight:

Check out this awesome core-periphery model video.

Make a 3 Column Chart in your notes, record qualities of the Core,  Periphery, and semi-periphery.

 

Below the chart, write 3-5 sentences documenting the connection and interaction between the 3 regions.

By the way, what kind of region are the core, periphery and semiperiphery?

Electronic Wasteland

Electronic Wasteland | Walkerteach Geo | Scoop.it
Photographer Pieter Hugo documents the Agbogbloshie slum.
Luke Walker's insight:

This photo gallery of images from the electronics dumps in Ghana. The developed world produces an enormous amount of electronic waste that cannot be recycled given that many of the materials used to produce computers, cell phones, etc. are highyl toxic. Local people search through the dump, to retrieve precious metals and components from the wasted electronics. The remainder is burned releasing toxins into the air.

Questions to Ponder:

How can computers be redesigned to avoid this problem?

How can governments react to this situation to stop the export of electronic waste to places like Africa, China, etc.?
How can electronic manufacturers be held more accountable for the quality of their products?

Luke Walker's insight:

Very informational video on the subject of electronics and the need for more sustainable production of electronics.

How many cell phones have you had? What will you do when you replace it? Can it be recycled? Can we do better?
