The Ecology Box covers ecosystems, food webs, habitats, and water/soil quality monitoring. Students will investigate water and soil quality, study habitats ranging from a drop of pond water to a rotten log, and learn about population change through various case studies. At the core of this unit is a long term project where students build mini-ecosystems with water collected from a local creek, soil from the schoolyard, and seeds. Their ecosystem will be monitored over one month as the plants grow and the water quality changes (measured by pH, temperature, dissolved oxygen, and water volume). In the second month, students will design their own experiments with their mini-ecosystems. Student teams will model various human environmental impacts (pollution, acid rain, global warming, etc.) and observe the effects on the plants, soil, and water in their mini-ecosystem.
