1. Mesocosm (aka ecosphere)

2. Definition (wiki) A mesocosm is an experimental tool that brings a small part of the natural environment under controlled conditions. In this way mesocosms provide a link between observational field studies that take place in natural environments, but without replication, and controlled laboratory experiments that may take place under somewhat unnatural conditions.

3. IB Skill: Setting up sealed mesocosms to try to establish sustainability

4. I will provide… 3 fresh water shrimp Gravel Your task is to create a sealed environment which keeps you shrimp alive for the longest possible time. We are not going to deliberately kill these creatures!

5. Think about.. What are the needs of freshwater shrimp? Which plant will be most suitable? How much water should you use? What else will the shrimp need? How long do you think your shrimp will survive?
