Bottle ecosystem

Make a Pop Bottle Ecosystem to show illustrate how the animals, plants, and non-living things in an environment all affect one another. Also includes a lesson on responsibility.

Our most recent science unit is an exploration of ecosystems. We learned there are 4 parts to an ecosystem: animals, plants, decomposers, and non-living things. These bottles contain all four parts including water, soil, grass, fish, snails, gravel, worms, and a water plant. Our bottles have been self sustaining. For two weeks we haven't had to feed the animals or water the plants, and everything is still alive. Take a look:

Single-tail goldfish need 100+ gallons PER FISH and good filtration. A pond is the best choice for them. They’re social fish and should be kept with 2 or more other goldfish. This doesn’t even come close to providing those, and these fish likely died within days.

Biome BOttles...awesome third grade teaching about ecosystems!

Ecosystems come in all sizes. Creating an ecosystem in a bottle can be a fun and affordable way to learn about species interactions and the basics of aquarium care. Fish are highly complex creatures making it hard to create a self-sustaining ecosystem that doesn't need extra food input or cleaning.

Don't let the title, DIY 2-Liter Bottle Ecosystem Project scare you. This activity is fun and intriguing for the home or a science project!
