Tenth Session - Planet Guardians - Application Phase
In this phase of the project Planet Guardians students continue to develop the product which was assigned to its subgroup and also keep using all the knowledge learned in the preparation phase using Thinkquest.org.
During this week's work on the products continued, although attendance in the classroom was not the best and we miss a day of Internet. But nothing will prevent the Planet Guardians do their job:
During this week's work on the products continued, although attendance in the classroom was not the best and we miss a day of Internet. But nothing will prevent the Planet Guardians do their job:
Let's take an eye in our products:
1) Scientific Article - MS Publisher 2007
Planet Guardian member, Susan, working in the scientific article in MS Publisher 2007. Susan is member of the The Green Hornets subgroup. This subgroup has the duty of create the scientific article of the data results and analisys of the Sabana Llana investigation.
2) Data Results and Analisys Presentation - Logger Pro and MS Power Point 2007
The subgroup The Guardians Dreamers working in the Data Results and Analisys Presentation.
3) ArcGIS Explorer - Dynamis Model map
The Green Brain subgroup has the commission to work on the dynamic model of water quality research in the Sabana Llana stream in ArcGIS Explorer.
The map will include the data we collect using Vernier LabQuest. We will also have the analysis of the results obtained in the investigation of water quality in the Quebrada Sabana Llana and in addition we have pictures of the tables and graphs showing the results of this research.
4) Documentary Video - Adobe Premier
The video documentary are the products that more work is needed because there are to do various tasks within the development. Subgroup Discovery Kids has the job of creating a video documentary to show the entire research process, its purpose, application and solution to the problem of water pollution issue.
They are using Adobe Premiere for the editing of the video clips taken in the field trips and in the classroom. Students will use media as images, video clips, music, narration and text to make this video documentary. All these resources have been taking as the project continues in its development.
5) Planet Guardians Blog - Blogger.com
The subgroup Natural Beauties Blog will touch the project work. The student Liana and her team is working hard on developing the Blog. Are creating entries for each meeting of the blog and these are accompanied by some pictures and video clips for the enjoyment of visitors, we hope you like it.
6) Participation in Thinkquest.org assessments tools
And this story will continue....

Session Eight - Data Analysis and Results - Vernier Logger Pro - ArcGIS Explorer Dynamic Model
Water quality collected points in the Río Piedras can be considered generally acceptable in terms of water use, based on national and local standards. Water quality in items collected from the Río Piedras has decreased slightly over the years, given the urban expansion in this area. Activities such as: population growth, industrial and agricultural increased activity, could create a negative impact on the water supply in the near future. Moreover, according to the data obtained during our field work, we conclude that the quality of water from this Río Piedras point is good. The levels of pH, conductivity, dissolved oxygen and turbidity are normal and optimal for the survival of aquatic organisms and for domestic use.
This project is still at the stage of research and analysis of results. We will create a dynamic model using ArcGIS technology, will publish a scientific paper to report results and in addition will prepare a "blog" for the publication of results on the Internet.
The temperature of a body of water affects its overall quality. The water temperature out of "normal" range of a stream or river can cause damage to aquatic organisms that live there, such as larvae "stonefly" or mosquitoes. Our results may be compared with the temperatures of the rivers in the U.S. during the summer.
The DO of a body of water is the amount of oxygen in water. The measurements obtained at this point in Rio Piedras have the minimum amount of DO for optimal living conditions for organisms. The DO is 4.7mg / L which is the average in this area.
The pH is a measure of acidity or alkalinity of a solution. The pH indicates the concentration of hydronium ion present in certain substances, in this case, water. According to our research the Río Piedras has an average pH of 7.68. This pH is optimal for the survival of all marine organisms. Water quality at this point in Rio Piedras is generally acceptable for domestic use.
Turbidity is a measure of the lack of water clarity. High turbidity water is cloudy, while water with low turbidity is clear. The cloudiness is caused when light is reflected on the particles in the water. Therefore, the more particles in the water, the greater the turbidity. Our results show that this river has water that is safe to drink. This water is visibly cloudy due to turbidity levels above 5 NTU.
Current flow, or flow, is the volume of water that moves over a designated point for a fixed period of time. It is often expressed in cubic meters per second (cfs). At this point in Río Piedras flow velocity is not of great intensity. At the time of the sample, the river was calm and flow velocity was mild.
The conductivity of a substance is defined as the ability or power to conduct or transmit heat/ electricity. Pure water is a good conductor of electricity. According to the results, the sample has high levels of conductivity. The normal level of conductivity in a river or lake is 5.5 mS / cm. Our readings were of 381 mS / cm.

Third Session - Data Collection- Rio Piedras - Guaralcanal
This Saturday January 29, 2011 The PR Water Cops CL- Mater Salvatoris will have their second data collection in a diferent spot of the Rio Piedras river in San Juan, P.R. The club has a total of 10 students between the ages of 10-11 years. They will be taking water samples in various sites of the river. The students will use Vernier Labquest with water quality sensors. This water quallity package includes pH, turbidity, dissolved oxygen, condutivity, temperature, nitrate, chloride, ammonium measures, among others. For this, a technology teacher (José Hernández) will lead us. Also, students' will be present to assist us.
See you there!
See you there!

Escuela Verde Te Quiero Verde
In order to raise awareness in the school community about the need to protect our natural resources, Santillana and the Association of Private Education of Puerto Rico presented the First Competition of Environmental Projects: Green School, I love green. "
Green school, I want you green is a competition for environmental projects aimed at students, teachers and student associations of schools affiliated to the Puerto Rico Private Education Association.
To enter, contestants must submit an essay that contains a description of an environmental project carried out in a school or community. The essay must be accompanied by photographs or videos that demonstrate the efforts made for the environment at school in the community. Projects can be on cleaning the school or community, tree planting, recycling projects, guidance on measures to improve the environment, environmental education courses offered at school or ecology club, among others.
The contest ends on February 11, 2011 and the awards will be distributed on February 23, 2011, at the Convention of the PR Private Education at the PR Convention Center. Winners will receive cash prizes in different categories.
CL Water Cops feel very proud to partner with the Mater Salvatoris school for the completion of this project. It will be a very interesting and enriching experience for both students of the Environmental Science Club and for master trainers who will be the "coaches" of these "Water Cops".
