Environmental Footprint & Land Use in Pinchot
Regular maintenance of the vehicle can help save about $126 dollars annually reducing consumption on services and in the process reduce carbon emissions by 909 pounds. In addition, turning down of the temperature of the heating thermostat by eight degrees Fahrenheit and the air conditioner by seven degrees Fahrenheit can provide savings of $24 and $42 respectively. This will save about 770 pounds of carbon dioxide from being released into the atmosphere. Activities, such as washing clothes in

Samples of the soil
The containers were then labeled after soil was collected and covered tightly.One of the few tests run in class using the soil samples was using the observation technique. Through observation, the color of all the samples from the dump side and the stream side were determined by all the students and the findings recorded. The color was determined by simply looking through the colorless containers and writing down the color. While in the containers, the color was brown for the samples from both

Water Quality Lab
In the year 1970, NSF (National sanitation foundation) identified a standardized method of measuring the quality of water. This is the water quality index or WQI. It is generated through data obtained from nine parameters of water quality tests. In this case, the value for the raw data would be normalized to a score of one and one hundred using the graph of Q-value. Q-value is always multiplied by the weighting factor as per the test of relative importance to the overall quality of the steam.

Native Plants versus Non-Native Plants
The Texas Department of Agriculture lists the Chinese tallow tree (Triadica sebifera) as an invasive species. It is a fast growing weedy tree of Chinese origin with milky sap cultivated for seed oil. It was introduced in America in the 1700s as an ornamental tree as well as for production of seed oil for soap making (Burke’s backyard 1).From the results and analysis of the Chinese tallow tree, it survives both in acidic and basic soils and is drought resistant. Consequently, when grown in

WATER QUALITY AND CONTAMINATION
The study found that the various chemical substances that leached through the soil such as “nitrate and ammonium” and other metals that had their orgin in sewage sludge can reach underground “deeper than 0.8 m,” thus contaminating “shallow aquifers” (p. The experiments conducted by Lee et al used column and pilot scale experiments to reveal that heavy metals from abandoned mines also contaminated groundwater. However, by using “lime as a coagulant,” the researechers were able to

Molecules and Processes of Life Activity 6 - Cellular Respiration and the Effects of Pollutants on Its Rate
To test our first hypothesis, the experimental design was such that yeast was mixed with water then poured into a test tube. A wider test tube was placed over the yeast test tube and flipped together over 10 minutes to observe the level of gas amounting in the wider tube. The amount of gas was recorded every minute in the10 minutes. The same was done to a yeast-water mixture but with granulated sugar added into the mixture.To test our second hypothesis, another mixture of yeast and carbohydrate

Environmental Contamination
Of the 80,000 known chemicals, EPA only tests 200 of the probable contaminants. This presents a high likelihood that some contaminants escape notice. Contaminants like 1,4 dioxane has been found to be persistent in the environment especially since it binds to water and relatively hard to remove since small concentration of it have been found in water even after purification and filtration. Most of the water supply has been found contaminated by 1, 4 dioxane that is an indicator of

Comparing the CO2 in the school carpark and the field during the day and after school day.
The CO2 sensor mounted on the stand is placed outside around the carpark and the field area with free air circulation. The sensor was fastened on the clamp stand with the adhesive tape. The digital surveillance cameras were set at strategic locations to ensure that every car driving to the car park was noted and measurement recorded after every thirty minutes timed by the stopwatch.The recordings should be done between 10 a. and 3 p.m after school. That means that recordings will be taken 4

How does amount of CO2 vary in the places with a high amount of cars comparing to the fields.
The study aims at proving this hypothesis.The variables include two aspects that are the amount of carbon dioxide and the place or environment that is between a place with a high amount of cars and fields, which have a small amount of cars. In the study, the level of carbon dioxide provides the dependent variable whose volume depends on the environment and the activity in it in relation to cars. This means the environment is the independent variable. To understand further the effect that cars

How does amount and type of petroleum used by the people influences air pollution in different regions.
Very few family members share one car. According to the results from the survey, 68% of the family members have their own cars, 22% own two cars and 10% have three cars. Majority of people start to drive from the age of between 17 and 20 years. This is represented by the 65% of the result while 30% start to drive from the age of 13 and 16 years.

Another hypothesis was that an organism will have a lower rate of cellular respiration with a source of carbohydrate and a pollutant than when there is a source of carbohydrate and without source of pollutant. The pollutants are thought to play a role in interruptions that occur in cellular respiration.There are two types of cellular respiration which both depend on energy. The two types of respiration include aerobic and anaerobic respiration. In aerobic respiration, there is the inclusion of
