Knowledge Constructor


Cleanopolis VR is a game that students can play to learn more about the environment and fight against climate change. The game does not have to be played with 3D technology, but it will enhance the experience. Cleanopolis has both an Android and iOS version. 

Students will:

  • Be able to experience virtual reality while planning the Cleanopolis game. 
  • Understand what climate change is and how they can help lessen CO2 emissions. 

Vocabulary Words:

  1. Virtual Reality: Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. 

To prepare for this lesson:

  • Download the Cleanopolis App on your device and then on your student devices. 
  • Decide whether or not to obtain VR (Gyroscope for iOS, Google Cardboard, 3D glasses Android) for the students. 
  • Watch the video on Cleanopolis. 

This is a description from the website of Cleanopolis:

Captain Clean needs your help. Your mission if you accept it is to fight against climate change and make sure the city of Cleanopolis get rid of its CO2 cloud.

Assisted by your faithful companion named Tobby, explore the 3D city and discover its districts. They shelter some mini-games, some quizzes and even a movie theatre! Thanks to your actions, you will reduce the CO2 emissions and beautify the city. 
For an even more immersive experience and a wow effect, play with 3D glasses!
- Four districts to explore
- Eight fun mini-games to improve your reflexes and reduce the emissions of greenhouse gases
- Some quizzes to evaluate your ecological footprint and to learn how to improve it 
- One movie theatre with an educational film starring Igloo the penguin who explains climate change
