Beaty-Warren Middle School

The students at Beaty-Warren Middle School would like to thank all participants for a great experience. We had a lot of fun completing this project and comparing our results with the results from the other schools. The data that has been submitted from us came from May 12th. All of the classes collected water samples at different locations along the Conewango Creek. Our final reports follow by period.


Period 2

We learned many things while participating in this project. We learned what the various tests where actually testing and what problems could occur because of those factors. We learned that our water is very health. We have accepted our hypothesis because our water was better that the other schools when all of the tests were considered. In the future, we would like to have tested other locations and also completed all of the tests instead of just 5.


Period 3

We learned that water is very complex. We learned how to run the various tests. We also learned that water quality is very different is various places around the world. As we interpreted our results, we learned that our water quality is excellent. We have accepted our hypothesis because our water is better overall than the other schools. If we were to do this again, we would be more careful with the testing equipment so we did not break it. We would also like to test more often and in different places.


Peroid 4

We learned how to run the various water tests. We learned that our water is not polluted. We are accepting our hypothesis that our water is of better quality than the other participating schools when all of the tests are considered. If we were able to do this again, we would like to be able to test for all of the different parameters instead of just five.


Period 5

We learned that there are many different parts that need to be considered when deciding if water is healthy. We also learned that each of the tests have different ranges that have to be considered also. We used five different test kits in our analysis of the water. We determined that our water is of good quality. When we compared our data to the other participating classes, we feel that our water is of better quality than the other schools when all of the tests are considered. Due to the analysis of the data, we have accepted our hypothesis. If we were able to participate in this study again, we would test more often and maybe even test in different places.


Period 6

We learned many different things while we participated in this study. First we learned how to actually complete the tests and that there were a lot more things in the water that could affect its quality. We also learned that our water was much better than we originally thought and that it is better than most other places. When we compared our results with those of the other schools, we found that our water quality was very good and so we have accepted our hypothesis. If we were able to participate in this project again, we would like to be able to test all of the included parameters instead of just five. We would also like to test in other places instead of just one.


Period 7

We have learned numerous things this year. We learned how to run the various tests. We learned how to work better with different groups of people. We learned that here are many factors that can influence our water quality and that we can make a difference in the health of our creek. We compared our data with the data from the other schools and found that our water is better then theirs. Do to this fact; we are excepting our hypothesis because the test results showed our water was of better quality then the other participating schools. If we were to begin this project again we would listen to our teacher better so we wouldn’t break our equipment and know how to use the chemicals better too. We would have also liked to test more often and to include the tests we never had done.

Period 8

By doing this project we learned that the water is cleaner than it looks and how to safely and correctly perform the tests. We compared our data to the data of the other schools and discovered that our water, overall, is of better quality than the other schools. Due to this we are accepting our hypothesis that our water is the best. Next time we might test more often or test different parameters. Also, we may test in different locations. As a result of this project we have discovered that we can have a great impact on the quality of our water.

hypothesis
Delhi, the capital city of India is facing the challenges of sanitation and environmental degradation due to increasing population and urbanisation.yamuna river receives huge quantity of waste and sewage from the city.

data
The colour of the Yamuna water was slightly yellowish in colour. Some of the things we noticed in theYamuna water were several kinds of worms.the temperature was 30,ph was 8,dissolved oxygen ,nitrate and phosphate level was 8,4,1ppm respectively.

interpretation
The pH level was 8 which was slightly basic, the dissolved oxygen was 8 ppm which is fairly good , however the nitrate level was 4ppm which is quite highand phosphate level was 1ppm.The reason for high nitrate level in the sample tested was due to cultivation of crops on the bank of the river where good amount of nitrogen fertilizers were added which got dissolved in river water due to the process of leaching .

conclusion
Our starting hypothesis was that the water in Yamuna river would be contaminated because of the surroundings. It is a river in one of the populated city,Delhi. After we tested the river, we found that we were very wrong. the reason could be due to the initiative and various projects taken up by the government in recent years to maintain the quality of water.

learning and future prospects

We learned many things by participating in this project. We learned how to use different equipment to collect samples, how to test those samples and what the results indicate about lake quality. We also learned about the quality of other lakes, creeks and rivers from other countries around the world. If we do participate in the project again, we would like to have more schools from around the world participate so there would be more data to compare. Thank you for the opportunity to participate in this project.

Hypothesis: Will water the water quaility of Hovey Lake improve over a years time?

We tested the water quality of Hovey Lake on April 24, 2003. Four groups of approximately 28 students tested the water for pH, dissolved oxygen, temperature, nitrates, and phosphates. These tests were run last year, and we hoped to see better or equal water quality.

Water Analysis:
pH - average 8.0 (same as last year)
DO - 6 ppm (improvement of .9 from last year)
temp - 24.7 (increase of 9 degrees celsius)
nitrates - 0 ppm (same)
phosphates - 1 ppm (same)

We conclude that there has been no increase in pollution, due to the nitrate and phosphate levels. The pH was adequate for all life. The temperature increased signicantly. This may be the result of more direct sunlight. Last year we tested on a cloudy day, and this year it was sunny. The dissolved oxygen was a little better, which is suprising because the temperature of the water was warmer. Again, this probably was due to the direct sunlight.

In our micro and macroinvertebrate study, we found mostly aquatic worms and insect larva. Both types of organisms are tolerant to poor water quality. With further study, we did find some sensitive protists.

Overall the water quality was good for all organisms. Therefore, we did not see any significant change from last years test results, except for the temperature increase.
