Eco-column Project – Organism Guide

Directions: You and your partner will be required to purchase and bring in an aquatic organism and a terrestrial organism for your eco-column project. This guide will help you to pick the organisms that will survive best in the eco-column.

General Tips:

1)  Most pet stores (Petsmart, Petco, etc.) require you to be 18 years old to purchase fish or other organisms. It might be smart to bring a parent with you if you aren’t already 18.

2)  Fish won’t survive very long in the transport containers/bags that are given to you at the pet store. Try to purchase your fish either the night before or the day that the project starts.

3)  DO NOT bring in a family pet to put in your eco-column!

4)  The more organisms that you put in your eco-column, the more difficult survival will be. Try to limit yourself to 1 or 2 organisms in each half of your eco-column.
