Integration Ideas

Math:  Estimation Activity
Visit Amusement Parks around the U.S. or world where there are high resolution images of the parking lots and having them estimate the number of: A. cars in the parking lot, B. Park attendance based on the average number of people per vehicle, etc.
Geography:  Maps Then, Earth Now
The US Library of Congress has a huge collection of maps. Some of my favorites are the old panoramic maps where the towns are drawn in '3D'.

It might be interesting for students to use images from the library in creating overlays to show population growth and development over time.

The collection can be browsed at:

Social Studies:
Virtual tour of historic sites, wonders of the world, battlefields, important cities, etc. with links to websites full of valuable information to help students with research.

Language Arts:
Tour the birthplaces of literary figures or the cities that set the stage for novels.

Look at the environments and populations of nations all over the world to discuss the impact of environment, health care, natural disasters, disease, sanitation on people and their survival. (Add in statistics from Culture Grams in the Pioneer library to really bring the point home.)

Explore earthquakes, volcanoes, natural disasters, biology, and all other fields from a birds-eye perspective.  Abundance of links to data sources:

Foreign Language:
Explore the culture of nations that are being studies (French, German, Italian, Japanese, etc.) and visit landmarks, government buildings, and museums.
