Learning Objectives

  • Computational Thinking Practice 1.C.
  • IOC-1.A
  • IOC-1.B
  • IOC-1.E Explain how people participate in problem-solving processes at scale.
  • IOC-2.B

Essential Knowledge

  • IOC-1.A.1
  • IOC-1.A.2
  • IOC-1.A.3
  • IOC-1.A.4
  • IOC-1.A.5
  • IOC-1.B.1
  • IOC-1.B.2
  • IOC-1.B.3
  • IOC-1.B.4
  • IOC-1.B.5
  • IOC-1.B.6
  • IOC-1.E.1 Widespread access to information and public data facilitates the identification of problems, development of solutions, and dissemination of results. IOC-1.E.2 Science has been affected by using distributed and "citizen science" to solve scientific problems.
  • IOC-1.E.3 Citizen science is scientific research conducted in whole or part by distributed individuals, many of whom may not be scientists; who contribute relevant data to research using their own computing devices.
  • IOC-1.E.4 Crowdsourcing is the practice of obtaining input or information from a large number of people via the Internet.
  • IOC-1.E.5 Human capabilities can be enhanced by collaboration via computing.
  • IOC-1.E.6 Crowdsourcing offers new models for collaboration, such as connecting businesses or social causes with funding.
  • IOC-2.B.9
  • CSN-2.A.3
  • CSN-2.B.3
  • CSN-2.B.4

Details

1. Introduction to Crowdsourcing (10 minutes)

  • Define crowdsourcing.
  • Ask students to read The Scientist in Us All (or read it out loud as a class).
  • Discuss key concepts in the article about Crowdsourcing:
    • What are the benefits?
    • How is this different than the Folding at Home program we learned about when we discussed parallel and distributed computing? How is it similar?

2. Group Activity (10 minutes)

  • Divide students into four groups.
  • You can use the Group Generator program to randomly sort students.
  • Assign each group on of the four cutting edge scientific puzzles:
  • Give students time to review the site as a team.
  • Task them with taking notes on what the puzzle(s) are trying to solve and be ready to share with the other groups.

3. Share (10 minutes)

Each group shares: What scientific puzzle(s) the site they researched is trying to solve? How are they trying to solve it through crowdsourcing?

4. Bitcoin Mining (10 minutes)

*Define Bitcoin.

  • Explain the hazards of Bitcoin Mining.
  • Ask students to discuss the following questions:
  • What is the positive intention of Bitcoin?
  • What are the negative consequences of Bitcoin mining?

5. Homework

  • Students can start their homework.
  • Read pages 15-26 of Chapter 2 Blown to Bits.
  • Stop at "Because You Can't Live Any Other Way."
  • Use the Notetaking template to take notes.
