31. Design an Ecosystem Project Groups of 3 - 4
You must design an ecosystem that will can be sustained in a sealed mesocosm for the next month.
Requirements - Utilize at least two plastic bottles in your ecosystem
- Include a terrestrial and an aquatic ecosystem in the sealed mesocosm
- The two environments must be able to interact with each other (i.e. nutrients must be able to move between them)
- Consider some aspect that you would like to test each week about your ecosystem and plan for testing it each Friday. (dissolved O2, CO2, Soil pH, Temperature, Nitrates)
First Step – Do research using the following terms “Ecocolumn”, “Sealed Mesocosm”, “Biology In a Bottle” to get ideas. Sketch out a plan for how you want to construct your Ecosystem. Remember the nutrients that need to be cycled through the ecosystems!
Second Step – Gather the materials for construction of your mesocosm. If you would like any fish or small invertebrates to live in your ecosystem, you need to provide them. I have the following : Gravel, Water Plants, Water, Soil, Netting, Bottles, Tape, Scissors, Terrestrial Plants
Third Step – Implement your design! Set up each of the mesocosms in a sink (in case they leak), and observe the variable you decided to measure each week!
