2. PROBLEM: The problem that we are investigating in this project is the water quality.

3. BACKGROUND KNOWLEDGE ALL LIVING THINGS NEED WATER TO SURVIVE USEFUL SUBSTANCES INCLUDE DISSOLVED OXYGEN SOME HARMFUL SUBSTANCES INCLUDE NITRATES AND PHOSPHATES NITRATES ARE NEEDED BY PLANTS AND ANIMALS TO BUILD PROTEIN, BUT TO MUCH CAN BE HARMFUL PHOSPHATE IS AN ESSENTIAL NUTRIENT FOR PLANTS AND ANIMALS GROWTH, BUT CAN BE DANGEROUS IF THERE’S TOO MUCH pH IS A MEASUREMENT OF THE ACIDIC AND BASIC QUALITY OF WATER TEMPERATURE AFFECTS THE AMOUNT OF DISSOLVED OXYGEN IN THE WATER

4. BACKGROUND KNOWLEDGE II pH of natural water is between 6.5 and 8.5 Dissolved oxygen is important for animals to live in the water Most aquatic animals are adapted to a certain pH level and could die if it changes Temperature is vital to water quality

5. HYPOTHESIS: If we analyze tap water then,it might have a low amount of nitrates.

6. Independent Variable:Type of Water Sample Dependant Variable:Outcome of parameters tested Constants:Amount of water,number of tablets used,the same chemicals Control:No control EXPERIMENT

7. Procedures: First we collected water samples from the creek, pond, taps and bottles Second we tested the temperature,nitrates,pH,phosphates,and dissolved oxygen for each type of water Third we matched the result color from the tests to a little chart indicating what the colors meant Later we recorded the results from the tests performed Lastly we cleaned up and put the equipment away as directed

12. Conclusion ● The water quality was tested for all 4 water types(pond,creek,bottled,and tap) ● From our results we found that all water types had an excellent pH,dissolved oxygen,nitrates,and phosphates ● All the pH were excellent for life as well as the level of phosphates,dissolved oxygen,and nitrates that also allow life ● Each water’s results were exceptional and all could maintain life ● In conclusion all the water are drinkable but the pond and creek waters are not clean enough to drink and they all can support living organisms
