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 do these numbers mean? what do these units mean? What is a "lot" or a "little", a high or low reading?
* 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.
* Students who had an egg in their home will approximately locate their house and put a dot on the map.
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.
Over the next week
Students create a Research Note with their own observations of:
* the highest reading of a particular sensor (in units)
* the lowest reading of a particular sensor (in units)
* A guess about the contributing factor to those extreme readings
Next batch of students take home eggs, set them up and create a Research Note with:
* Photo of where the egg is installed
* Two photos of what is nearby the egg that might affect air quality
* Writing about any observations they have or challenges they encountered
Note: as with first egg batch, eggs will remain installed for 2 weeks before students return the equipment and upload data from the Sd card.
