Ecology is the study of our natural environments and the interdependency of each of its parts. Air, water, soil, plants, animals and living organisms combine to create the ecosystem we live in. The KELVIN® Ecology Lab provides information and hands-on activities for students that will help them learn about this fragile relationship. The KELVIN® Ecology Lab is divided into five activities each focusing on a different aspect of ecology. Students will explore: Hard and Soft Water, Pollution of Ground Water Systems, Acid Rain and Water PH, Soil Nutrients and Particulate in the Air.
