Hello ! I am a sixth grader attending [|Amigos School] in [|Cambridge, Massachusetts]. This Wiki will be about an ecosystem, right here in Cambridge! It will help you learn about the biotic and abiotic factors in and near our river. Have you guessed it yet? It’s the [|Charles River]! I got all the data from a class field trip my teacher brought us on.

We arrived at the Charles River at 2:00 pm. We were walking all the way from our school. The first thing most students noticed was the awful smell of the Canadian geese. But we were relieved once we started seeing and smelling the grass, trees and dirt. After a while, we checked our thermometer that read 18° C. Then we did the water temperature which was 14° C. The turbidity was 8 JTU (Jackson Turbidity Unit), and the pH was 8. The last thing we measured was dissolved oxygen, which was 4 ppm.

At the Charles River, there are many living things! I found tall trees, star chickweed and other wild flowers like Greek valerian. Those are the producers. They’re the ones who make the food for the animals. And those animals are called consumers because they consume the plants’ food. There were ducks in the river. Near it, there were a lot of Canadian geese. Flying above there were bees, loudly buzzing, full of energy and waiting to sting! The decomposers at the river were the worms in the ground, the algae in the river and the racket fungus on the trees. The decomposers’ job is making sure that no dead material is left. Go Take a look at my web for more information. Then, take a look at my energy pyramid!

Going to the Charles River was awesome because my whole class had a chance to learn something new. We learned how to measure water in 4 ways! You could measure the turbidity, the temperature, the dissolved oxygen or the pH. We measured all of those using just one water sample from the river. We also got to sit on the ground and observe the birds. But, before we could identify them, they had flown away. Overall, it was an amazing field trip because we got to find out how biotic life and abiotic factors work in the city.
