Go Green! - Mixtures and filtering

During the last Go Green lesson, students explored the topics of filtering and separating the mixtures. First, they prepared a mixture of colored chalk with water, and then added Himalayan salt, sea salt, dishwashing liquid and peppercorns to it. Later they filtered it through a pre-prepared filter kit. As a result, the children learned what a homogeneous and heterogeneous mixture is. They also learned the concept of suspension.
