Water Pollution In Water

There were 3 different groups of the critters. If they were in the 1st group the water wasnt polluted, if they were in the second group the water was somewhat polluted, and if they were in the 3rd group, the water would be polluted. We found more critters living in group 1. In the graph it shows that we found 88% of the critters in group 1 are living in the water. The critters we found in group 1 were the gilled snails, water pennies, and the mayflies. It also shows that in group 2, only about 2% of the critters living in the water. The insect we found in group 2 was the crayfish. Than, in group 3, it shows that 10.7% of critters are living in the water. The critters found in group 3 were the dragonflies, worms, and the pouched

As a group, we did an experiment of billbug and what kind of water they enjoy to stay. Our team was used for experiment sugar water, salt water and plain water. We measured the material we wanted to use. We used salt for 2.0 g. We used sugar for 2.0 g. and we used plain water for 10 ml. We mixed 10 ml of plain water into 2.0 g of sugar and 10ml plain water into 2.0 g of salt. We placed one tissue for each chamber. We dropped in chamber one the salt water. We dropped chamber two the sugar water. We dropped chamber three the plain water. In the middle of the chambers we placed filter paper. Then we put 5 billbugs and let them free to move anywhere they wanted. After 5 minutes we recorded how many billbugs are on each side of the chamber. We

The Mummichogs minnows are used to observe the effects from anthropogenic chemicals in our pollution. The purpose of this experiment was to find out the effects of these

The U-high freshman biology class designed an experiment to test the question; based on the number of micro invertebrates, what is the water quality of the U-high creek? On 9/22/14, the day of the experiment, the conditions were recorded at 10:05 AM. The temperature was 55 degrees with a 6 mph wind, and 62% humidity. One of the observations of the creek is that there was some garbage and trash on the banks, although there was minimal amount. Another observation was that there was run-off leading into the creek from roads, nearby parking lots, and neighboring yards. There were about 40 small fish, only about 2-3 inches long swimming north against the current. The water was also very clear, and the bottom was clearly visible. Based on the observations

The procedure for this experiment followed the steps as shown in the flow chart (Figure 1) and will be expanded upon here. The oxygen-measuring probe in the test chamber was first turned on and required 10 minutes to warm up. During this time, two empty containers had 200mL of fish water added to them and then each was weighed using a scale that was tared to zero before use. Two pairs of goldfish were then collected from the large tank #1 in the lab room using the fish net provided, and one pair was placed in each container. Then, the containers were reweighed separately and the original weights were subtracted from the new weights in order to determine each pair of goldfish’s weight. Two trials were conducted and in each trial, each goldfish pair was subjected to two conditions, first a control condition where no factors were introduced, followed by an experimental condition where they were exposed

we counted the little critters that live under rocks. then we sorted them into 3 different groups. group 1 they are pollution sensitive and found in good quality water. group 2 are somewhat sensitive and can only live and good are medium quality water. group 3 are tolerant to pollution and can be found in any quality water.

The outcome of this lab proved for the prediction to be true. The organisms in the aquatic chamber died out and the water quality slowly deteriorated before the lab ended. Although the organisms eventually died, there was a time when the aquatic chamber was able to support life. The aquatic chamber had its own food chain where the fish ate the plant to stay alive. Furthermore, the water quality of the chamber began to deteriorate over the few weeks becoming a cloudy murky brown color.

Once the sponge was inside the jar, because it expanded in the water we used the tweezers to squeeze the sponge to remove any air bubbles in the stoppered jar. Next, we removed the cap of the spring water and poured it into the stoppered jar until it overflowed and capped the two calibrated oxygen probes back onto the jars. We then immediately took the initial oxygen concentration (mg/L) and temperature reading (°C) from the machine. Then, at every 15 minute mark in a one hour time period, we took the readings of each fish by counting their gill movement in and out as one ventilation for 30 seconds using a stopwatch. Before reach reading, we recorded the oxygen level and temperature and recorded the results. The focus of the experiment was to see how the ventilation rate and oxygen consumption are affected by the different treatment levels. The method used to analyze the data and the results was called the t-calculated or the t-test. By finding the average, standard deviation, and given the N1 and N2 values, the t calculated value was determined. By using degrees of freedom (D.F) and t calculated it would determine whether the confidence level (C.L) is high enough to support our alternative hypothesis and reject our null hypothesis, or low enough to reject our alternative hypothesis and support our null hypothesis. If the t-calculated value is higher than the t critical values, then the alternative hypothesis is supported and the null hypothesis is rejected. But, if the t-critical value is greater than the t-calculated value, then the null hypothesis is supported and the alternative hypothesis is

Purpose: The purpose of this lab is to identify the element that is causing the fish in the Halibut tank to die, by testing each variable between both of the identical tanks.

My topic is based around the invasive species lamprey. They cause problems that damage fisheries. The only way to rid of these beasts is through specific methods. Along with some facts about lamprey themselves.

Water pollution in Tennessee is a major environmental issue. Polluted rivers and streams are major problems because the water inside of them is supposed to be a clean source of water, but sadly that’s not the case. In order to stop this, we have to keep moving forward to find a solution.

Sophia Fortune CCR 092 King October 31, 2017 Summary Response of Virginia Woolf’s “The Death of the Moth, In the "Death of a Moth" by Virginia Woolf, Woolf compares the wonder of life and death by using a moth as an example of the simplicity of life and death and that we need to accept the inevitable of life and how death fallows, though putting up a fight is an essential part of this whole process. Describing a mostly overlooked creature, a moth, as it exists in nature, particularly on the September day. Woolf unable to concentrate, captivated by the moth, but yet also distracted by the work going on in the fields and the movements of the birds in the background. Considering the moths life "pathetic," especially as this is not a real moth because it flies during the day.

In the first experiment, my partner and I were retrieving rocks from the Conodoguinet creek and observing the organisms on them. We were doing this because there are organisms that cannot survive in pollution. Those organisms are called group 1 organisms. There are 2 other groups. Group 2 organisms can survive in slightly polluted water, and group 3 organisms can survive in any water. If we found a lot of group 1 organisms, than that would tell us that the water was not polluted, or if it was, then it was only very slightly polluted. When we had finished observing the rocks, we noticed that we had found more group 1 organisms than group 2 or 3 organisms. That means the creek is not polluted, or if it is, then only very slightly.

Experiment: On Friday, we put the beaker of pond sample to the fridge. The beaker was in the fridge for 2 days. After taking it out and doing observations on Monday, we realized that every organisms in the pond, from the little algae to the big bugs, is
