Day One
To construct the ecosystem you need the following supplies:
- five clean two-liter bottles with caps
- scissors
- push pin or awl
- clear tape
- soil, water, plants, compost, small snails, spiders, worms, etc
The directions for constructing the system can be found in my MSP EARTH Science binder or in the book Bottle Biology.
Our aquatic layer contained water from the Mandeville Water Treatment outdoor water garden. We also included 2 minnows, a snail, duckweed, and other aquatic vegetation. In our composting layer we had layers of soil and humus. Our top terrestrial layer contained soil and several small plants. We then placed our ecosystem in a window careful to avoid direct sunlight.
