Crack the Code: Water Systems

Meghan Polowin
Students learn about the water treatment process as they complete a digital “escape room” on a Google site.

Summary

  • Students will learn about how municipalities process and manage water
  • Students will learn about different careers related to the water treatment process
  • Students will develop digital literacy as they solve series of puzzles using a Google site
Specific Expectations for Ontario

Grade 8 Science, Strand: Water Systems
2.2 investigate how municipalities process water (e.g., obtain it, test it, and treat it) and manage water (e.g., distribute it, measure consumption, and dispose of waste water)

2.7 use a variety of forms (e.g., oral, written, graphic, multimedia) to communicate with different audiences and for a variety of purposes (e.g. using appropriate scientific conventions, draw a labelled diagram of a water treatment facility; create a brochure about the safe use of wells and septic tanks)

Setting the Stage

Clean drinking water is a universal human need, but in many parts of the world it is not always available. In Canada, we are very lucky to have vast quantities of fresh water, as well as systems for processing and managing this water so that most Canadians have clean water to drink.

By navigating through the “Crack the Code: Water Systems” Google site, students will read career profiles, have the opportunity to do a hands-on activity, as well as complete puzzles and quizzes about water treatment processes and careers.
