Teach this lesson with your class to unlock Emoji World and make it a better place for all emojis.

Unlock Emoji WorldCLC Week

Key Coding Concepts

  • Algorithms
  • Conditional Statements
  • Functions
  • Sequences

Terminology

Library

A bundle of reusable code that allows a programmer to achieve something that would otherwise be difficult or impossible. In this case, easy graphics programming.

Function

A list of statements that can be invoked repeatedly in a program, perhaps changing its behaviour on the basis of “parameters” that are passed in.

In this lesson, learners will use Python and the Pygal graphing library to visualize data about one of the most important issues facing our country: greenhouse gas emissions and their relation to climate change.

Before the lesson...

  1. If your learners are new to Python, begin with this Python Code-Along “Intro to Computer Science”: http://bit.ly/teenslc-python-code-along
  2. Show learners how to navigate Trinket, as done in the video above. Demonstrate how to edit and run code. Show learners how to navigate within the course using the arrow keys (top, right).
  3. Guide learners along through the Trinket lesson, or have learners progress at their own pace.
  4. Complete the main activity available at: http://bit.ly/trinket-data-vis-python (also linked in the slides)

Emoji World

  1. After you teach, go to canadalearningcode.ca/emojiworld and get a unique code that will unlock Emoji World for your class
  2. This will give each student access to Emoji World so they can see how their new coding skills made an impact (and then have fun making Emoji World continue to grow!)

  • See “Advanced (Optional) Topics” section of Trinket course for Python extensions.
  • Brainstorm how your class can take action. What can we do to help (A) spread awareness, or (B) help solve this issue?

  • Have learners document at least one bug they encountered and how they solved it using the Debug It! Reflection questions in the Creative Computing Curriculum from the Harvard Graduate School of Education.
  • Make a plan for how to access students’ work in Trinket. You could sign up for Trinket Connect (https://trinket.io/schools) to collect projects, have students email you class links, or gather project links in a shared Google doc or blog.
  • Reflect on what we learned from this data:
    • What stood out?
    • What is something new that we learned?
    • What questions do we still have?

    The K-12 Computer Science Framework

    Although learning how to build digital projects is a key part of Computer Science education, students should also learn a wider set of skills and competencies that will help them to harness the power of digital technologies as both creators and consumers. A comprehensive approach to K-12 Computer Science education includes learning about the following five focus areas:

    View Framework ➝

    Programming

    By the end of high school, students should be able to create a simple computer program.

    Programming Lessons

    Computing and Networks

    By the end of high school, students should understand and be able to use the tools and devices commonly used to build digital projects.

    Computing and Networks Lessons

    Data

    By the end of high school, students should be able to explain how we use computers to create, store, organize, and analyze data.

    Data Lessons

    Technology and Society

    By the end of high school, students should be able to explore the ways in which technology and society have mutually shaped each other.

    Technology and Society Lessons

    Design

    By the end of high school, students should be able to apply design principles to the digital projects they create.
