Water filtration

Water is a chemical substance composed of H20 molecules. Water is found naturally in the sea, lakes and rivers, but also in the groundwater. The water in our bathrooms and kitchens comes mainly from these last two sources.

But before reaching our taps, water must undergo a series of treatments to “clean” it of impurities and contaminants. It then passes through a water treatment plant also called a wastewater treatment plant…

But then, how to “clean” the water? What are the stages of filtration?

This is what you will discover in the “water filtration” module of the Saphir application, developed by the CNRS-LIRIS. Download the SAPHIR application.

The Saphir module on water filtration allows to :

Présenter aux enfants ce qu’est l’eau

Expliquer pourquoi il est nécessaire de la filtrer

Montrer comment nous filtrons l’eau à grande échelle

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Expliquer qu’il est possible de filtrer l’eau soi-même

Démontrer par une simple expérience scientifique comment la filtration de l’eau par soi-même est possible

Aider les enfants à assimiler ce savoir via différents exercices (Quizz, mémo, associations et expériences)

If you’re interested in learning more, we invite you to try the Natural Water Cycle educational module in our Sapphire app.
