The effect the ph and Dissolved Oxygen of water in the Cove River have on the cloud type and height Abstract The purpose of this experiment was to figure out the effect that the pH and dissolved oxygen level of water in the Cove River have on the cloud type and height. Cove River is located to the West of West Haven High School. The site supports research in archeology, water quality, and plant life. Dissolved oxygen can be generated by the plants in the water, going through photosynthesis, and by the diffusion of oxygen in the atmosphere. Results – The Effects of pH and D.O. Conclusions The purpose of this lab is to determine the effect of pH and dissolved oxygen in the water on the cloud formation around Cove River site. The hypothesis: “If the pH and dissolved oxygen levels of the water in Cove River are too low, then the clouds around Cove River will form at a low height because the lower pH will cause more substances to dissolve in the river and weight the clouds down. The additional weight of the low dissolved oxygen will cause lower cloud formation.” was not supported by our data because there was not a trend between the pH and dissolved oxygen levels. A possible error could have been made in picking the types of clouds. An uncontrollable error, such as rain prior to the taking of data, could have changed the pH of Cove River. Another error that conflicted with our data was caused by a lack of not know the actual height of the clouds. The height of the clouds were assumed by their type. An error when taking the dissolved oxygen of the water is one must take the dissolved oxygen from the water as soon as possible because the atmosphere changes the D.O of the water. Another source of error is the gas station next to cove river contaminates the water the gas station had a leakage and it’s been dumped into the river. The experiment can be improved by checking future cloud type results with a professional meteorologist. More data can be taken to gain a greater understanding of the effect that the pH of water has on cloud type and height. Problem Statement IV: Uncontrolled change of pH and D.O. of the Water in Cove River DV: Height and Cloud Formation Hypothesis Statement If the pH and dissolved oxygen levels of the water in Cove River are too low, then the clouds around Cove River will form at a low height because the lower pH will cause more substances to dissolve in the river and weight the clouds down. The additional weight of the low dissolved oxygen will cause lower cloud formation. Site of Data • Methods • Go to Cove River. • Observe the clouds and figure out what type they are. • Obtain water from Cove River in a bucket. • Use Vernier probeware to measure the pH and D.O. of the water in Cove River. • Repeat steps 1-4 five times for five days or at a random monthly basis. Future Directions In order to gain a greater understanding of the effect the pH of water and dissolved oxygen level of water has on the height and formation of clouds, research can be continued at a regular rate, and at more occurrences. There are other variables that could have affected results that were not taken into account in this experiment, such as temperature, nitrate, and salinity levels. To increase reliability in future results, it would be important to include these variables. By: Jacob Yisehak Michelle Diaz Sebastian Moraga Data Tables References Palmer, Chad. "Cirrus Clouds."
