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.
The cases, from your handoutNot recorded
The same cases as your handout, in the same order.
Scenario 1 · Foundational
A seismology lab wants earlier earthquake warnings. It releases a free app that quietly uses each phone's motion sensor: when thousands of phones in one area shake at the same moment, the lab's servers detect the quake seconds before it spreads. Two hundred thousand people have installed the app. Rule on the project.
Definition test (a large number of people? via the Internet?) + your ruling:
Model + what the crowd contributes (data, money, or other input):
Enrichment - why only a crowd can do this (what scale buys):
Scenario 2 · Core
A rural clinic needs a solar-powered vaccine refrigerator that no local funder will pay for. A nurse posts the project on a platform where anyone can pledge money; 4,800 strangers pledge an average of $9 each, and the refrigerator ships within a month. Rule on the project.

Scenario 3 · Stretch
A television network announces its cooking competition will be 'judged by the crowd': five celebrity chefs, selected by producers, will score each dish through a private scoring website that only the five of them can access. Rule on the project.

Scenario 4 · Challenge
After a hurricane, a relief agency posts fresh satellite images of the flooded region on an open mapping site. Overnight, 11,000 volunteers around the world - students, gamers, retirees - trace the passable roads and mark damaged bridges tile by tile. By morning, rescue drivers are navigating with the volunteer-built map, and the agency publishes it for every other relief group to reuse. Rule on the project.

About the line in your handout
Your handout says this exercise is available online and auto-graded. The exercise IS here, and it is the same work in the same order, but the auto-graded half is not written for this topic yet. Nothing on this page is scored or sent to your teacher.
Hand this in the way your teacher asked for it. Topic 1.1 has its graded check today, and the rest follow.
