Class Home

Class Presentation: Instructor leads class in demonstrating how to upload and look at example data using the COSM web interface. In the background, additional facilitators are uploading the SD cards with two weeks of logged data to COSM.

  • 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 on COSM
  • 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.
