Trees And Carbon

Activities

To understand the environment, it is important to understand how organisms and their surroundings interact. Since all organisms use energy, we need to understand how energy can be used and transferred. Because all organisms are made of substances, it is equally important that we understand how chemicals are used and transported through an ecosystem. This exercise will help contribute to our understanding of the movements of compounds in ecosystems. The transport and transformation of substances in the environment are known collectively as biogeochemical cycles. These global cycles involve the circulation of elements and nutrients that sustain both the biological and …

Ecological Footprint

Activities

Estimating your overall impact on the environment is a daunting task when you consider all the variables involved. Environmental scientists have developed a tool that does just this however, and presents the information in a manner that is easily visualized despite the underlying complexities. It is known as an “ecological footprint”, and it describes the area of land needed to supply the resources used and wastes produced by each individual. Nature’s ability to provide resources and process wastes is known as “natural capital”, and the goal of sustainable living is to use resources wisely so as to avoid depleting natural …

Fossil Fuel Capstone

Activities

In this capstone activity, we are going to try to look at our individual fossil fuel usage. It would be nice if we could actually calculate how much each on of us is responsible for using. However, a great deal of our personal fossil fuel usage is hidden from us and almost impossible to calculate. For instance, the food that we eat was produced using oil in the fertilizer spread on the crops, fuel in the tractors that plowed the field, and diesel in the trucks that brought the food to market, amongst other things. The newspaper you read in …

Natural Gas

Activities

In the world of fossil fuels, natural gas is often the overlooked ugly duckling. It gets lumped in with oil, as in “oil and gas industry”, even though the discussion usually centers upon oil. It does not help that gasoline, which is derived from oil, is shortened to “gas”. In many people’s mind, the “gas” in “oil and gas” refers to gasoline, and not natural gas. However, natural gas has much to offer as an energy source that makes it preferable to other forms of fossil fuels. It burns much cleaner than coal or oil, and it produces far less …

Coal

Activities

Coal has been a source of energy for almost as long as Homo sapiens have inhabited the planet. The earliest record for its use dates back more than 3000 years to China where it may have been used to smelt copper. In areas where coal seams intersected the surface, coal was a ready supply of energy just waiting to be exploited. It did have some drawbacks, though. Most of the coal near the surface burns dirty, requiring some form of chimney if it is to be used indoors. It is also heavy to transport, limiting its use to regions near …

Oil

Activities

We are a country that runs on oil. From the gasoline in our cars to the plastic in our computers to the detergents that we put in our dishwashers, we rely on oil for our modern way of life. It cannot be understated just how strong of a role it plays in our economy and politics. It is used in tractors that plow and harvest food. It is used to power manufacturing plants and as feedstock in commercial goods. It powers all the trains and trucks that bring goods to market. It runs our cars, heats and cools our homes, …

Nuclear Energy Capstone

Activities

The United States has a problem with energy independence. The problem has nothing to do with a lack of energy production or availability. We are the largest producer of energy in the world, and have centuries’ worth of fossil fuels, as well as an enormous supply of nuclear and alternative energies, at our disposal. Our energy dependence on other countries is a result of the fact that we are also the leading consumers of energy in the world, being second only to Canada (population 32 million, compared to the 283 million in the U.S.) in per capita consumption of energy. …

Radiation Exposure

Activities

Nuclear energy was going to make the world a much better place during the 1950’s. The promise of an almost limitless supply of cheap energy that did not produce any soot or atmospheric pollutants almost seemed to good to be true. During the 1960's and 1970's, the United States nuclear industry expanded, as fears of a looming end to oil and gas reserves fueled construction. But by the late 1970’s, though, the wheels had come off of the nuclear wagon. The cheapness of the energy never did pan out, as prices of electricity from nuclear energy rivaled those of fossil …

Nuclear Power Plants

Activities

As we discussed in the last activity, energy is released when isotopes decay. This energy can either be in the form of electromagnetic radiation or the kinetic energy of the nuclear fragments. The important question for us is, “How can this energy be converted into a useful form like electricity?” The most obvious thing to do is to allow either of these forms of energy to be absorbed by a substance in order to increase its internal energy and thus, increase its temperature. As the substance warms up above its surroundings, a temperature difference is created, and allows for any …

Nuclear Decay

Activities

Almost any phrase that has the word “nuclear” in it has a bad reputation. The term conjures up images of mushroom clouds and radioactive mutants. It is interesting to note that in the 1940’s and 50’s, the term that applied to energy derived from the decay radioactive material was atomic energy. This term was somewhat correct, since the energy was coming from the breakdown of the atom. It was not until later that the more appropriate term nuclear energy was used as more people began to understand that the energy was coming from the breakdown of the nucleus of the …

Home Energy Capstone

Activities

The other three weeks of the Home Energy Module study energy flow and usage in our homes. In the R-Factor activity, we observed that the material used in the construction of our homes has a tremendous impact on the rate at which heat flows through its exterior surfaces. In Home Audit and Home Analysis activities, we performed an energy audit of our homes to estimate the amount of money that it costs to power it. As you have seen during our studies, there are many factors that affect the cost of energy in our homes. The right choices of materials, …

Home Analysis

Activities

The average household spends over $1,300 a year for energy to run the many devices found in the home. In this week's lab, we are going to investigate ways to save both energy and money that will not seriously impact your current lifestyle, i.e. you can keep watching as much television as you like, but you might want to put on a sweater to do it. In order to do this, we are going to have to use the measurements of our homes that we made two weeks ago. Last week, we studied how different materials affect the amount of …

R-Factor Of Various Materials

Activities

Even though it has been over 150 years since the First Law of Thermodynamics was discovered, we still find that heat is misunderstood. For example, the many environmental science textbooks define heat as "the total kinetic energy of atoms or molecules in a substance not associated with bulk motion of the substance." THIS IS WRONG! What these books are describing is the thermal energy of a system. This is a common misconception. While heat is energy, it is not a containable form of energy since, by its very definition, heat is energy that is transferred. In particular, heat is the …

Home Energy Audit

Activities

In the 1800's, scientists found, empirically, that rules exist that determine how energy can be transferred. The first of these rules is called the First Law of Thermodynamics. This law is usually stated as, "Energy can neither be created nor destroyed; it can only be transferred from one form to another." This often leads to the re-titling of this law as the Conservation of Energy Principle since it says that energy must be conserved. This statement of the First Law does not say anything about how energy can be transferred, though. It turns out that there are only two ways. …

Basic Skills Capstone B

Activities

If you look at the leaves that fall off of the trees in autumn, you will notice that not all leaves of the same kind are alike. Some are larger than others, some are longer or wider, some have different stem lengths, and some may have slightly different shapes. This is not surprising if you consider that they may be from different trees. Just as two people have hands or feet of different sizes, so different trees may have leaves of different sizes. If you do further observations, however, separating out leaves found under one tree from leaves found under …

Basic Skills Capstone A

Activities

In the late spring and summer, many parts of the United States experience smog alert days - days when the concentration of pollutants in the air has been considered unhealthy. Many of these pollutants are produced by automobiles - particularly hydrocarbons, carbon monoxide, nitrogen oxides and, indirectly, ozone. Most discussion of the adverse effects of smog center on humans, and the effects on other forms of life, such as plants, are scarcely mentioned. So how does air pollution from automobiles affect plant growth? Let's think about how this hypothesis might be tested. Two problems must be addressed. The first is …

Measurement

Activities

In general, you are quite familiar with measurements, as almost any occupation requires measurements of some kind. Carpenters measure boards for cutting, nurses measure blood pressure in patients, tailors measure fabric for garments, and advertising executives measure the public's acceptance of their sales pitches. You will therefore undoubtedly be utilizing measurement in your chosen career, regardless of the field you enter. Measurement plays a particularly large role in science. In their studies, scientists gather data, and to do this they use measurements. Scientists measure the concentration of gases in the atmosphere, the growth of organisms under varying conditions, the rate …

Statistics And Graphing

Activities

Statistics - they're all around us, and we're exposed to them every day. They allow us to summarize large volumes of mathematical information, and so are found wherever there's data to be presented. Let's say you're watching your favorite college football team, and the game has come down to a last second thirty-five yard field goal attempt for the win. When describing the kicker's past performance in this range, the play-by-play announcer doesn't list all of the kicker's attempts one by one and their outcome, he simply states the percentage of kicks made in this yard range. If the kicker's …

Experimental Analysis

Activities

Central to good science are accurate observations, testable hypotheses, well-designed experiments or other tests, and reasonable data analyses. The purpose of Laboratory 1 is to introduce you to the basics of designing and analyzing experiments. The following two laboratory exercises will provide you with further steps in organizing and analyzing data. Many interesting experiments are impossible to do in a normal undergraduate science laboratory setting. For this reason, your introduction to designing an experiment that has relevance in “the real world” involves a computer simulation. The program involves a growing industry, that of farming fish. What is your favorite kind …

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …

Ocean Optimism, Jenna Pannone, Madison Mark, Crista Kieley

Environmental Studies Student Projects

In our class, Intro to Environmental Issues, we focused on marine mammals for a section. We chose to highlight two cases, the Hawaiian Monk Seal and the Vacquita, in which severely endangered species may have a chance at survival due to the work of highly dedicated individuals and organizations. We wanted to raise awareness of these species, the work being done, and the power we have to create change.

Evaluating Trophic Rewilding As A Conservation Technique, Aaron Sieve

Biology: Student Scholarship & Creative Works

The focus for this paper is to define specifically trophic rewilding, determine its efficacy as a conservation technique, and explore ways to lessen one of its key limitations. Trophic rewilding is the conservation technique whereby an extirpated keystone species or ecosystem engineer is reintroduced into a degraded habitat to restore ecological function by triggering trophic cascades. The technique is evaluated through analysis of the concepts of trophic cascades and ecosystem engineers. Key limitations of trophic rewilding are that a lack of population control in reintroduced may cause issues, that many times not enough is known about trophic cascades to be …

Using Consumer Accessible Mobile Devices To Collect Vehicle Emissions Compliance Data, Joshua N. Jensen

Regis University Student Publications (comprehensive collection)

The emissions inspection procedure has been largely stagnate for the last 20 years. Vehicle owners in the United States spend approximately 1.7 billion dollars annually for a technician to perform the simple task of plugging an emissions inspection computer into their car’s computer. Smart Emissions was developed as an Android application to provide a new procedure for emissions inspection utilizing consumer-accessible mobile devices and an ELM327 Bluetooth adapter. With Smart Emissions, vehicle owners utilize the Android devices they already own to connect to a Bluetooth adapter inserted into the diagnostic link connector port of their vehicle. The adapter communicates with …

Environmental And Climate Justice Along The Brahmaputra River In Northeast India, Costanza Rampini

Faculty Publications, Environmental Studies

The glaciers of the Himalayas are the source of all of Asia’s major rivers and are crucial to Asia’s water supply, economies, and livelihoods. The Himalayan region is uniquely vulnerable to the impacts of anthropogenic climate change, while also becoming one of the most dammed regions in the world. This case study explores the unequal distribution of the impacts of climate change and dam building along the Brahmaputra River in Northeast India. It examines how the combined impacts of these two processes negatively affect local communities and explores environmental and climate justice issues. In discussing climate change impacts and hydropower …

In Continuity With The Past: Indigenous Environmentalism And Indian Christian Visions Of Flora, James Ponniah

Journal of Global Catholicism

This article considers whether Indian Christianity can be said to have a distinctive ecological vision. The first two parts of the article examine Christian environmentalism in two native forms of Indian Christianity: Tamil Christianity and Tribal Christianity. Continuing with the theme of conformity to the local culture—though of the elite—the third part of the article investigates how Christian Ashrams function as dynamic centers for ecological praxis. The last part of the article considers how contemporary Indian Christian communities can respond to the ecological challenges confronting them.

Abstract

Refrigerants have been one of the causes of ozone depletion and the buildup of greenhouse gases in past decades. When the international agreements the Montreal Protocol, which has the goal of eliminating ozone depleting compounds, and the Kyoto protocol which has the goal of eliminating greenhouse gas emissions, where implemented they paved the way to replace past and current refrigerants with alternate compounds that are less detrimental to the atmosphere. New compounds that where green-lit by the EPA for use as refrigerants in 2011 where HFO-1234ze and HFO-1234yf, both of these compounds have a very low Global …

Chapman University 2016 Environmental Audit: Residence Life Dining Services Equipment, Alexandra Fw Sidun, Devon T. Bloss

Student Scholar Symposium Abstracts and Posters

Chapman University accommodates over 1700 student meal plans per day through the on-campus dining services provided by Sodexo Restaurant Services. The commercial-grade kitchens found in the Randall Dining Commons (RDC) of Sandhu Conference Center are frequently used to prepare food for students for every meal, seven days a week. The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy …

Crafting A Campus Sustainability Action Plan: A Grassroots Approach, Jolina A. Kenney

Celebration

In recent decades, colleges and universities have taken a leadership role in developing institution-based Sustainability Action Plans (SAPs). A SAP includes a summation of past achievements, current initiatives, and the prioritized goals and implementation strategies for future action in terms of promoting environmental sustainability. These plans can also serve as pedagogical devices that teach students, staff and faculty important lessons of intentional living, global citizenship, and environmental responsibility. While many plans are adopted as top-down initiatives, there is great value in finding ways to engage the entire campus community in such endeavors at the grassroots level. This project documents a …
