I’m asking my friends to save 2-L bottles for me. Why? First I want to make Bio-columns. Bottle Biology has the basics for making TerrAqua Columns. Here is the Decomposition Column and Kimchee Column. This Bottle Green House is similar. There is an experiment comparing an open and closed ecosystem. Next is a Berlese Funnel and this lab, Litter Critters, a fairly sophisticated lab, measuring biodiversity. Use bottles to make a Wormery. (Make a Water Filtration System; filtration is more Earth Science, rather than Biology. Hey, if you have extra bottles, kids like this lab.) Here is a Predator-Prey Column. The Niche Kit uses bottles and film canisters. Make a simple bottle bird feeder. Start saving bottles!
