Class Home

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.
