Ecocolumn Lab Report Explanation

Soil and Water Measurements Look at your plant height graphs (including elodea). Discuss what happened with your various plants over time and the possible reasons for the changes. Look at your water pH graph. Discuss what happened with pH over time and the possible reasons for the changes or lack of changes. Look at your water dissolved oxygen graph. Discuss what happened with DO over time and the possible reasons for the changes. Look at your water Nitrite/Nitrate graph. Discuss what happened with these measurements over time and the possible reasons for the changes. Look at your soil measurements: Temperature, pH, fertility. Discuss what happened with these measurements over time and the possible reasons for the changes.

Adjustments, Observations, Error and Design Discuss 2-3 adjustments. How did they improve your ecocolumn? Discuss your observations. What were the most significant observations? Why? Discuss mistakes and errors that were made during the ecocolumn lab and how they influenced the lab. Discuss how each of the chambers in the ecocolumn affected the other chambers

If an ecosystem is in balance,*insert what factors would cause it to be balanced*, then the organisms in the ecosystem will survive *insert how many weeks you think your organisms will survive* because they can exchange resources through *insert what cycles are involved*.
