In this Activity, students use multi-colored breakfast cereal and liquid to model the concepts of leachate and leaching from municipal solid waste disposed of in a landfill. Students create a modern landfill model with the same material. This environmental chemistry Activity can be used to complement a celebration of Earth Day.
In this Activity, students extract sodium zeolite A from powdered laundry detergent and examine its properties. The Activity helps students to apply their chemical knowledge to the realm of consumer products. It could be used as a lead-in for a discussion of environmental issues and water chemistry.
