Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of …

Environmental Studies Student Projects

Our book is a story about an elf encouraging children to go eco-friendly in order to help the environment. Santa delivers gifts such as a reusable water bottle to get children involved. By helping the environment, Santa's workshop is going to be saved from melting ice caps! The goal of this book was to get children involved to help the environment.

Ella Savesthe Beach, Leena Aly, Maddie Hodgdon

Environmental Studies Student Projects

The intention of this project is to start educating children on the consequences of polluting our planet with seemingly harmless waste such as plastics. Many do not realize how small plastic objects can be fatal to many animals. We asked elementary school children to collect trash as part of their participation. Then the trash was used to make a poster featuring Ella the crab. This poster is paired with a children’s story book, where Ella and her animal friends are featured dealing with the consequences of littering. The story book depicts how people’s behavior in natural areas can harm innocent …

Esmerelda's 1600 Feathers, Corinne Casey, Ellen Wise, Kendall Ericksen

Environmental Studies Student Projects

ESA’s 1,600 Feathers is a children’s story that was created in response to a Congress letter from August 2017 addressed to several members of the Committee on Natural Resources and Agriculture. This letter requested for the 1973 Endangered Species Act to be “modernized” in order to reduce the economic burdens it imposed on farmers and ranchers. They argued the existing ESA was a “clear failure” having only accomplished recovery and delisting of 42 out of the 1,652 plant and animal species under its protection. The intentions of our story were to highlight the endangered and threatened species that have successfully …

Colin The Cormorant, Chelsey Jankauskas, Samantha Schultz

Environmental Studies Student Projects

Colin the Cormorant was an art project created to represent the effects of pollution on local organisms, such as Colin the Cormorant. We hope by seeing this sculpture people think twice about how they dispose of their trash. Colin is made from trash collected at Fortunes Rocks Beach in Biddeford Pool. We chose to make a cormorant because we frequently see cormorants around the Biddeford Pool area and they are a seabird that has been impacted by various types of pollution (garbage, air pollution, etc.).

Baby Bay And The Big, Loud Ocean, Kelcey Salois, Dominique Mellone

Environmental Studies Student Projects

This is a children's book that depicts some of the serious effects of noise pollution on marine organisms, especially larger mammals such as Baleen Whales. Through this little story about a baby whale and his mom, trying to find the rest of their pod amidst an ocean filled with noise pollution, we hope to spread awareness about this problem and provide hope to younger generations that if we work hard enough at protecting our oceans, we can provide a much nicer and safer life for the creatures that live within it.

Democratic Civic Engagement: Transformative Local, Inclusive Decision-Making To Achieve Global Peace And Climate Solutions, Leah Ceperley

Biennial Conference: The Social Practice of Human Rights

The UN Sustainable Development Goals call for action on Climate (No. 13) and Strengthening Governance (No. 16) as imperative to transform our world toward one that is resilient, just, and peaceful. Climate change is a global problem, marked frequently in the U.S. by indifference, with far-reaching impacts disproportionately burdening the poor and vulnerable worldwide. Global in scope, its sources, impacts, and fields of action are local. Combating indifference at the local level can strengthen local governance structures, build trust across ideological divides, and shift the conversation from indifference to action.

Using an example from a University of Dayton-sponsored National Issues …

Encounters With Climate Change: How Sdg 13 Can Move From Awareness To Action, Rebecca C. Potter

Biennial Conference: The Social Practice of Human Rights

In a well-known passage from his book I and Thou, Martin Buber relates his encounter with a tree: “I contemplate a tree,” he writes, and then lists the various ways he could perceive the tree, as an artist or biologist, as someone interested in the trees parts and construction or interested in its function as a living system. But in all cases, Buber observes, “the tree remains my object and has its place and its time span, its kind and condition.”

Yet sometimes, “if will and grace are conjoined,” Buber describes being drawn into a relation with the tree wherein …

Human Energy Capstone

Activities

Movement is very important for humans. From our earliest days, we seem eager to get up and move around. The most celebrated moments of a child’s life seem to be geared around the ability to move: the first crawl, the first walk, the first bike ride, and (every parent’s nightmare) the first driver’s license. The ability to get around is one of the most cherished abilities and freedoms. For many Americans, our ability to get around when and how we want is almost considered a sacred right. Physics textbooks, which have many chapters devoted to motion, build a great many …

Efficiency

Activities

The previous two activities in this module have shown us the importance of conservation laws. These laws provide extra “tools” that allow us to analyze certain aspects of physical systems and to be able to predict the motion of objects in the systems without using more complicated analysis. Even in situations wherein we cannot exactly solve the motion, these laws are incredibly useful. For instance, if someone shows us an incredibly complicated device that can seemingly produce electricity with no energy input whatsoever, we know not to invest money in this device, as it must be a sham since it …

First Law Of Thermodynamics

Activities

In last week’s activity, we calculated the motion of objects by studying the forces on them. Using Newton’s Second Law of Motion, we were able to relate the forces on an object to the acceleration it experienced. The presence of constant forces led to constant accelerations, which corresponded to linearly-increasing velocities with respect to time. Comparisons made between the velocities we measured and those calculated from a study of the forces on the objects allowed us to validate Newton’s equation F = ma. In this week’s activity, we are going to investigate almost the same experimental setup as last week, …

Newton's Second Law

Activities

There are two ways to study the dynamics of a system in which there is motion. One of these is to study the kinematics of the system to see if there is any acceleration. If there is an acceleration, then this implies that there is a net force on some part of the system. If there is no acceleration, then this means that either there are no forces on the system, or that the forces within the system are all balanced. The other way to study the system is from an energy standpoint. Energy can flow from potential to kinetic, …

Population Growth

Activities

When George Washington started the first Presidency of the United States of America, he was governing less than 4 million people who occupied an area of 2,300,000 square kilometers. It was an agrarian society, with 95% of the population living on farms and only 5% in cities or towns of more than 2,500. There was plenty of land, and a vast array of natural resources, just waiting to be tapped. Today, we live in a country of over 294 million people. While we are one of the major food producers in the world, it is no longer due to us …

Age Structures

Activities

One of the tools that demographers use to understand population is the age structure diagram (it is sometimes called a population pyramid, but it is not always pyramidal in shape). This diagram shows the distribution by ages of females and males within a certain population in graphic form. Figure 1 shows a diagram in which the ages and sexes for the United States population are arranged so that ages are grouped together such as 0 – 4 years, 5 – 9 years, and so on. The population of each is group is represented as a bar extending from a central …

Population Statistics

Activities

For all of its futuristic stylings, the television show Star Trek was, like most science fiction, a commentary on the state of society at the time it was written (late 1960’s). One of the more famous episodes of that series was the one entitled The Mark of Gideon, which dealt with a planet that was so overpopulated that people did not have anywhere to sit down. At the time of the show, the Earth’s population was at about 3.5 billion, and was increasing at an incredible rate. The effects of such a large population on the environment were beginning to …

Toxic Chemicals

Activities

Humans have used chemicals for a long time. The ancient Egyptians used chemicals for dyeing, soldering and coloring metal, and making jewelry. The Industrial Revolution, which began in the middle of the 18th century, spawned the development of many new chemicals and chemical processes. Since World War II, the global chemical industry has boomed. Global production of chemicals was 1 million tons in 1930 and is now over 400 million tons. Environmental scientists study chemicals to determine if they are harmful to human health and the environment. Pretty much every chemical can harm you if you ingest too much of …

Home Chemicals

Activities

Chemicals are everywhere, in the air you breathe, in the food you eat, and in the chair you’re sitting on. Moreover, you’re mostly chemicals. Ninety nine percent of the human body is composed of just 6 chemical elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. After you die, you’ll decompose into hydrogen, nitrogen, water, ammonia, carbon dioxide, phosphoric acid, and sulfuric acid. So, from chemicals we come and to chemicals we go. Chemical elements are substances that contain one kind of atom and cannot be separated into simpler substances. There are 116 known chemical elements, of which 91 occur naturally. …

Mineral Identification

Activities

For this activity, we are going to try to identify ten different minerals from their properties. There is an attached listing of the major properties of the most commonly found minerals. Use it and any other resources you might have to identify the ten minerals, and list your findings on the sheet below. In order to help you by giving you a little practice with mineral identification, we suggest the following virtual identifier: http://facweb.bhc.edu/academics/science/harwoodr/Geol101/Labs/Minerals/ Your instructor will provide you with up to 10 different mineral samples for identification. To test for hardness, you will also be provided with a copper …

Plate Mechanics

Activities

Imagine a swimming pool that is totally covered with air rafts, with the air rafts neatly lined up end to end and side by side. Then imagine someone running up and doing a cannonball jump into the pool. Logically, the rafts will be thrust about with some of them jamming into each other, others pulling apart, and still others sliding past one another—and so it is with the tectonic plates of Earth: some of the plates are colliding, others are pulling apart, and still others are sliding past one another; therefore, understandably, where there are boundaries between the tectonic plates, …

Plate Speed

Activities

We are truly in motion no matter where we stand on the planet. The tectonic plates that compose the crust of the Earth are in motion at a measurable rate. Everything on the crust of the Earth changes its location in relation to the planet. Yes, the plates are moving over the mantle, and we can measure this motion to determine the rate of plate movement by figuring the distances and times involved. For example, if we know the past location of a certain island, then we can measure the distance between the present location of the island and its …

Earthquake Epicenter

Activities

In this week’s activity, we are going to try to locate the epicenter of an earthquake using readings from three different seismograph stations. This will be done by measuring the difference in time between the arrival of the P and S-waves. The difference it time of their arrivals is due to the difference in speeds for both waves. In particular, the difference in time is given by (distance to epicenter)/(Vp – Vs). Thus, we can find out how far away a particular seismograph is from an earthquake by solving this equation for distance. Since there are three stations, we can …

Climate Change

Activities

Global warming is a huge issue, not just because of the potential impact of the warming on the earth’s ecosystems, but also because the principal activity responsible for the bulk of emissions, fossil fuel combustion, literally fuels the engines of industrialized, urbanized societies. The stakes are huge -- international, political, financial, and environmental. In this exercise, you’ll learn about how to assess information sources, a critical skill in forming your own opinions and actions.

Ozone Depletion

Activities

While we often talk about the “Ozone Hole” over the Antarctic, we rarely talk about what ozone levels are like above our own heads. While the thinning of the ozone layer over the South Pole points to potential problems that we might experience here one day, it would be nice to know what our current situation is. In this week’s activity, we will do just this with the aid of data from 4 different satellites that have been monitoring ozone levels around the world for the last several decades. The Total Ozone Mapping Spectrometer (TOMS) Program was started in 1978 …

Acid Rain

Activities

Acidity is measured on the pH scale ranges from 0 to 14 with 0 being acid, 7 as neutral, and 14 as alkaline. The pH scale measures the concentration of hydrogen ions in solution, which indicates acidity. The pH scale is also logarithmic, so that a change in one unit represents a tenfold change in acidity, thus a solution of pH 4 is 10 times as acidic as one with pH 5 and 100 times as acidic as pH 6. "Natural" or unpolluted rainfall is slightly acidic and has a pH of between 5.6 and 5.8. When fossil fuels, such …

Air Pollution

Activities

The following exercise is designed to acquaint you with point sources of pollution in your neighborhood. The exercise utilizes the EPA’s Envirofacts website. Envirofacts allows users to search and find out information about pollution sources anywhere in the United States. You can also identify point sources of pollution in your neighborhood, learn about specific facilities, and create maps. To begin with, go to http://oaspub.epa.gov/enviro/ef_home2.air and enter your zip code. What will be displayed is a list of facilities in your zip code that have been issued an environmental permit. Scroll over to the “Stacks” column and then down the page. …

Atmosphere

Activities

The objective of this exercise is to have you observe atmospheric conditions as well as develop your understanding of major atmospheric concepts. For this exercise, you are asked to observe and record weather conditions for four days. In addition, you are asked to answer questions about your observations, as well as respond to a series of questions on general atmospheric characteristics. In the second part of the exercise, you are asked to perform a number of calculations relating to atmospheric conditions and characteristics.

Water Capstone

Activities

This activity is still under development. Please check back later for an update or e-mail John Pratte at jpratte@kennesaw.edu for more information.

Wastewater Treatment

Activities

When you think about the variety of materials that enter the wastewater system from a typical home, the list is diverse and extensive: wastes from toilets; soap, detergents, and cleaning products from drains and washing machines; food items from garbage disposals - all along with large quantities of water. How is this material removed so that the water may be safely returned to the environment and, possibly, utilized again by other people downstream? The answer depends on where you live. If your home is not serviced by a public sewer system, your wastes are undoubtedly treated with a septic system. …

Drinking Water Treatment

Activities

In this activity we’ll be treating "contaminated" water to observe firsthand the steps involved in purifying water for human consumption. The activity will use everyday items to carry out the steps in drinking water treatment and you will record changes in the water’s properties as the process progresses. The basic version of this exercise has you record the appearance and odor of untreated water as it moves through the various steps. In some situations, depending on available equipment and personnel, you may also be able to measure turbidity. Turbidity describes the clarity or “muddiness” of a water sample and is …

Water Use

Activities

If you’re like most people in the developed world, you don’t think much about water. Clean, drinkable water is delivered into your residence almost invisibly, and it’s always there when you turn on a faucet. As such, most North Americans don’t see the need for water conservation, particularly those who live in areas where freshwater supplies are abundant. But as populations grow and water supplies stay roughly constant, more and more pressure is being brought to bear on rivers, reservoirs, and groundwater aquifers and the need for conservation has become almost universal. These efforts are particularly crucial in areas with …
