Samples were taken from water sources on the hill near the school grounds and from the area around the dam. The soil appearance, odor, and Erosion were all tested by students to determine pollution in the environment surrounding the lake. Healthy soil would have minimal erosion, little to no odor, and a mostly clear appearance with the presence of plantlife and algae. The soil emitted a distinctly musky odor at the testing site on the hill, signifying the “presence of sewage discharge, livestock waste, decaying algae, or decomposition of other organic material.” This scent would indicate organic pollution. The
How the data will be analyzed? • The data will be analyzed by the use of a line graph. • And the data will also be analyzed with the use of a table. Hypothesis It is expected that the different fertilisers will have an effect on the growth of the duckweed Aim It is determined that the fertilisers will ensure a rapid growth on the duckweed to aid pond owners in avoiding to use said fertilisers so that their ponds will be rid of duckweed to ensure the life in the water will remain there. Rationale We deem the findings of our research as important because it will help pond owners maintaining their
1 “substrate” and another “ enzyme.” Instead of using the distilled water, this time you are going to use different pH buffer in the enzyme test tube. In the substrate tube, add 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL of guaiacol for a total volume of 7.5 mL. For the enzyme tube, instead of distilled water add the pH solution (3) and 1.5 mL of peroxidase which equals a total volume of 7.5 mL. Use the dH2O syringe for our pH solution. To clean the syringe, flush it by drawing 6 mL of distilled water.
We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms. We decided that, since there was not large variety, the creek is not as healthy as it should be. After the activity, I decided that the most important fact that I learned is that the healthiness of the creek is very dependent on the surrounding environment. In order to maintain the health of our creek, we need to be careful around it and not put pollutants into the creek or in the surrounding area.
One of the most difficult challenges that faces our society about water pollution is cleaning after a body of water have been contaminated. Our design team aimed to design a sufficient water filter that would improve the water quality in a body of water have been contaminated. An ideal body of water should be contaminant free, with a high potential Hydrogen (pH) and Nitrogen Dioxide (DO) level. Low pH and DO level which could cause health hazards to individuals who used the water as a drinking water. 2.
“Keeping a saltwater fish tank is about the same as keeping a tropical freshwater fish tank. If the right sized aquarium, good filtration, proper temperature, the right foods, and compatible tankmates are provided, many marine fish can successfully be kept, states, “Beginner Saltwater Fish, Hardy Marine Fish for Beginner Saltwater Aquariums”, in paragraph five. Saltwater and freshwater fish have some differences in their tank set up. For example, saltwater fish need more water per fish. It is also important that the tank remains stable
For fishing by controlling erosion as the roots of trees help to hold soils to keep them from flowing down into oceans and causing horrible damage to coral reefs, fisheries, and swimming areas. Especially in Hawaii, where we are surrounded with many oceans. That already have horrible items such as, plastic, litter, etc. To change this I will continue to do my monthly volunteer for beach clean-ups. Watersheds, provides habitat for Hawaii’s unique plants and animals, supplies cultural plants to continue traditions.
The pollution that we were testing for is where the acid came from to begin with. Dissolved Oxygen is another thing we tested for, that 's how much oxygen gets mixed within the water ( Ex. rapids - the white part of the rapids is the oxygen mixing with the water- .) We also tested how fast the water was moving or the ( speed/velocity. ) We were going to test it by using a bamboo pole with a string ( with a certain length ) and a bobber on the end and see how long it takes for the bobber ( from its full length ) to hit the bamboo pole.
We recorded each whether or not the counter actually counted the fish and then determined the percent accuracy for each level of sensitivity. This is important to test before it is actually in real-life use because we need to know the accuracy of the counter itself so we know the limitations when we use the counter to calculate population sizes and migration patterns. We also collected valuable data regarding what happens to the counter when a fish stops swimming and just sits in the tunnel, when a fish swims into the tunnel and then turns around and swims out the same way it entered, or if the fish was swimming really fast or really slow (even though speed should not be a factor). We found that in some cases, if the fish has passed at least two out of the
THEORY OF THE EXPERIMENT In this experiment change in the volume of reagents by diluting with water is used as change in the concentration and reciprocal of the time taken for the appearance of blue black colour as the reaction rate. Equation of reaction H2O2 (aq) + 2H+ (aq) +2I- (aq) I2 + 2H2O Hypothesis Hypothesis 1: Decrease in concentration of hydrogen peroxide (H2O2) decreases the rate of reaction (that is, increases the time for reaction to come to completion). In the reaction between potassium iodide (KI), hydrogen peroxide, Sodium thiosulfate (Na2S2O4) under acidic condition. Hypothesis 2: Decrease in the concentration of potassium iodide decreases the rate of reaction (that is increases the time for the reaction to come to completion). In the reaction between potassium iodide (KI), hydrogen peroxide, sodium thiosulfate (Na2S2O3) under acidic condition.
Too much chemicals in the water like lead, sulfur, chloride and fluoride can cause birth defects, cancer, Flu like symptoms. The chemicals in the water are supposed to provide a level of sanitation to the water. The issue with this though is that the chemicals added cannot be taken out of the water people drink. Every community has a water sample chart for what goes into their water. This was create by the federal government to provide the population with info about what is in the water.
The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound.
This would discourage people from polluting and would inform them on what happens if they do pollute the water. Evaluate one form of technology currently being used to purify and treat water and justify why it would be useful for the King River. An existing way of treating water with mine sediments in it is to first reduce the amount of pollutants entering the water. The water would then have to be treated with chemicals to get rid of bacteria. I think this technique would help to improve and purify the quality of the water but there may still be metals in the water.
The purpose of this experiment was to take the temperature, pH, secchi disk reading and to collect water samples to calculate the TSI, dissolved oxygen levels and phosphorus and nitrogen levels. These were all collected to determine whether or not the body of water sampled is experiencing turnover, which trophic state it falls into and the nutrient levels. The data included in this report is from the collective data that was collected during the experiment. The data included is presented in table or graph form, along with explanations of the results. Being able to calculate the TSI or determine if a lake is in turnover is useful in helping to determine the properties of the lake, such as if it has high or low plant growth or if it will have
If the acidity or alkalinity levels were high scientists would have to find a way to neutralize the acid and alkaline. We also did not find a high level of phosphates and nitrates in the water. My group also did a dissolved oxygen test on the water. The velocity of the surface water of the creek is at a normal rate. The Conodoguinet Creek appears to be healthy right now.
