Making water drinkable: Colloids
This online resource deals with the removal of colloids in drinking water.
In this online interactive learning object, students examine colloidal suspensions and how they affect water quality.
Students examine a range of colloids such as sols, aerosols, gels, foams and emulsions and have opportunities to participate in a variety of activities including a ‘To Do’ hands-on activity.
This resource is part of a series to do with the water cycle and water quality issues.
