Field Trip to Sabana Llana stream #1

On Thursday February 3, 2011  the Environmental Science Club of Del Carmen School  undertook the difficult task of being the investigators of the Sabana Llana stream water qualilty project, Planet Guardians. These high school students said present to this new adventure.

Twenty studentsof the Enviromental Science Club came to environmental science activities with their teachers. We also had the presence of Mrs Basora ,  the coordinator of the Enviromental Science club.
The class agenda was quite charged. We started at 3:45pm at the school computer lab, our meeting point . In this place Mrs. Basora took a record of attendees, an informal presentation of the participants and began with an orientation walk to the Sabana Llana stream.

Students took mesurements of water quality like: temperature, pH, DO, conductivity and turbidity. They followed the research protocol to the letter. Students took three runs with the same parameters in the two research sites. They had three rounds. The first round they will use the sensors of temperature, pH and turbidity. In the second round they will use temperature and conductivity. Then in the third ronund they will use temperature sensors and dissolve oxygen.

For next class we must do the same procedure but using the  ion sensors of calcium, nitrate, ammonia and chlorine.
