How this page works
The writing boxes below are yours. What you type stays in this browser, is saved here as you go, and is never sent to us or to your teacher. Hand the written work in the way your teacher asked for it.
The graded check at the bottom is the part that records to your teacher's gradebook.
Part B, from your handoutNot recorded
Your handout says these are the same items available here. Part A stays on paper.
Q1 · 3 points on the handout
The city where SkyCount is based releases its air-quality sensor records as free public data. Describe one problem the public could IDENTIFY, one solution someone could DEVELOP, and one way results could be DISSEMINATED - and name the EK principle that makes all three easier.
Q2 · 3 points on the handout
A skeptic says: 'These crowd projects don't enhance anything - people could always count birds and donate money.' Use one submission from the log to explain what collaboration VIA COMPUTING adds that was impossible before.
Q3 · 2 points on the handout
ENRICHMENT: SkyCount's dataset feeds real published research, yet anyone - including careless or dishonest users - can upload sightings. Describe two quality-control mechanisms a citizen-science platform can use to keep bad data out WITHOUT requiring contributors to be experts, and explain why that requirement would defeat the whole model.
