OBJECTIVE: 1.1.4 Understand the concept of direct proportion. 1.1.2 Understand the relative values of rational numbers. ACTIVITIES/ASSESSMENT: Finish working on the handout P 155 Additional Practice #3. Start on 5.1. Apply 5.1ff to science. NOTES: Virus on a head of a pin might work here. HOMEWORK: Page 43 problem 4.4

Interesting information about population density!

Based upon satellite measurements of city lights, this image is a map of the urban population density of North America. Red, yellow, and green are urban areas, and blue is the urban periphery. The city light data is laid over elevation data (black is sea level, light gray is over 10,000 feet). Most major cities are in level areas along an ocean, bay, large lake, or navigable river.
