Challenge 1:
Challenge 1:
Construct a sustainable small scale ecosystem in which you will investigate a human influence on the natural world. The ecocolumn has three chambers: the terrestrial chamber, the decomposition chamber, and the aquatic chamber.
SUPPLIES:
4-5 Bottles (2L plastic bottles work best)
Soil (from your yard)
Water (from a outdoor source is best)
Seeds
Leaf litter/ grass
Banana peal/apple core
Tape (Duct/masking)
OPTIONAL THINGS I MAY CHOOSE TO USE IN MY ECOCOLUMN:
Fish (guppies, shrimp, snails)
Algae or Other aquatic plants
Aquarium rock
Ants, Crickets, OR Other insects
Potato
Meal worms
Aquatic Plants (i.e. Duckweed)
Fruit flies
Worms
Livestock waste (goat, sheep, horse, cow, rabbit)
Research:
Jar Composting - Decomposition chamber
Points to ponder
Differences between the chambers
Food chains and food webs present
Biogeochemical cycles in action
Simulated ecosystems versus a natural ecosystems.
Describe the available niches
What limiting factors exist?
Evidence of ecological succession taking place in your column
The stability and sustainability of your ecosystem column
Step 1: Design a system
Step 1: Design a system
Draw a prototype of your ecocolumn:
Make sure it includes
How will material flow through the system
How will you make this a closed system
3 distinct chambers (terrestrial, water, and decomposition/composting)
A list of what will be put in each chamber
