Class Presentation: We are using Google Docs Spreadsheets to store and analyze our data. Spreadsheets are giant tables, with the X-axis labels telling us which data each Y-axis contains. Each row is a different data value at a specific moment in time.

• Discuss:

• What are numbers versus trends?

In Class Activity A:

• Students form groups and look at data from the example egg
• As other egg data comes online, students search for the egg that was in their house and look at their own data.
• Discuss how the class's eggs compare with each other.

In Class Activity B:

• Hand out a pre-printed google map of the Cypress Hills neighborhood.

Class exercise: facilitator demonstrates how to add a location to the COSM feeds for each particular egg, using location data noted on the maps by the students.
