How Many?

We have begun our study of world population growth. Students were shocked to learn there are 6.7 billion people on Earth. Check out this population clock to see how fast the world is growing...http://opr.princeton.edu/popclock/ .

We will be using the thinking skills of cause and effect to study population growth. Also, we will interpret demographic data and population pyramids. A simulation on world population growth went well and made clear to the students the concept behind the term "population explosion".

This week we will watch a video entitiled "The Population Paradox" that shows some of our population trends in action. Go to the link and check out some of the other resources on world population growth.
