A Liter of Light video about 4 minutes

The key for the study guide is here  

Day 1
Today, students learned about technology that is being used in the developing countries around the world to change lives for the better.  

The videos that we will watch about bringing light into very impoverished homes are
here:
1.

After learning of a very simple way to bring light into many homes using a water-filled bottle, students are to research other examples to share with the class.  

The form that they should use is
 Helping People in Developing Countries with Technology  - an exploration.pdf






Below are examples that I found that will be discussed in class.  On Thursday I will bring in one of these for students to experience in class.
