** This is the fifth annual 6th grade Wiki project about ecosystems around the [|Boston] area! ** **We tested the abiotic (non-living) of each place that we visited.This year we were equipped with [|test material] from the [|World Water Monitoring Day] organization.** ** We understand that the biotic (living) components depend and are differently adapted for unique abiotic factors like water temperature, dissolved oxygen, pH, turbidity, salinity as well as the type of geology in each site. ** ** We know how important the abiotic factors are to an ecosystem. Each ecosystem's biotic (life) components are adapted for specific abiotic factors. If the abiotic factors change too fast, the biotic won't be able to adapt in time, and the ecosystem will be in danger. **

**The students had a fantastic time at each site. They used their senses, climbed down the rocks, got wet, saw organisms that they had never seen before and worked as a team. They were eager to find as many organisms as they could!**

**We would like to thank the Cambridge Science Department, Susan Agger at the Maynard Ecology Center, and Captain David Weinstein and the Thompson Island Outward Bound staff all from the Boston Harbor Alliance for helping us to study two different ecosystems in the Boston Harbor Island (and for the amazing boat ride aboard the “Outward Bound”.**
