Lesson Plan - Where Does Our Garbage Go?, Center For Urban Resilience
Module 04: Hazardous Waste
In this lesson, students will explore what happens to garbage after it is thrown away. The first activity looks at the garbage itself. Garbage will be classified as either biodegradable or not, and connected to the principle of the conservation of matter. The second activity concerns garbage disposal methods. Students will participate in a jigsaw activity where they learn about one garbage disposal system, and then will teach their peers about the different systems. The focus will be on the advantages and disadvantages of each method. The third activity is a debate which shows that garbage disposal issues can disproportionately …

Lesson Plan - Ecological Impacts Of Hazardous Wastes, Center For Urban Resilience
Module 04: Hazardous Waste
The main purpose of this lesson is to demonstrate the idea that the things we throw away may harm other organisms. This lesson uses a brainstorming activity, and a lab experiment testing the effect of toxins on brine shrimp. This lesson also introduces the major pathways through which hazardous waste enter aquatic and terrestrial ecosystems and provides an overview of the impacts of wastes such as heavy metal ions, strong acids or bases, and persistent organic compounds on plants and animals.

Lesson Plan - Not All Waste Is Created Equal, Center For Urban Resilience
Module 04: Hazardous Waste
In this lesson, students will learn about the distinction between hazardous waste and other forms of waste as well as discuss the current challenges we face in finding ways to safely dispose of this waste. First, students will discuss their own conceptions of hazardous waste. Then, they will view a teacher-directed PowerPoint which provides additional information about hazardous waste. The lesson then concludes with the viewing of videos that relate to e-waste management issues.

Module 04: Hazardous Waste
This lesson continues on the topic of ecological impacts of hazardous waste and focuses specifically on the process of biomagnification. Students will read a case study about mercury poisoning in Minimata, Japan. Students will construct a food web diagram of a Minimata Bay ecosystem and then they will create a graph of mercury concentrations versus food chain position. This lesson also incorporates the idea of environmental justice.

Environmental Science Faculty Publications
Doping heteroatoms such as nitrogen (N) and boron (B) into the framework of carbon materials is one of the most efficient methods to improve the electrical performance of carbon-based electrodes. In this study, N-doped carbon has been facilely synthesized using a ZIF-8/polydopamine precursor. The polyhedral structure of ZIF-8 and the effective surface-coating capability of dopamine enabled the formation of N-doped carbon with a hollow structure. The ZIF-8 polyhedron served as a sacrificial template for hollow structures, and dopamine participated as a donor of the nitrogen element. When compared to ZIF-8-derived carbon, the HSNC electrode showed an improved reversible capacity of …

Social Distancing And Testing As Optimal Strategies Against The Spread Of Covid-19 In The Rio Grande Valley Of Texas, Kristina P. Vatcheva, Josef A. Sifuentes, Tamer Oraby, Jose Campo Maldonado, Timothy Huber, Cristina Villalobos
School of Mathematical and Statistical Sciences Faculty Publications and Presentations
At the beginning of August 2020, the Rio Grande Valley (RGV) of Texas experienced a rapid increase of coronavirus disease 2019 (abbreviated as COVID-19) cases and deaths. This study aims to determine the optimal levels of effective social distancing and testing to slow the virus spread at the outset of the pandemic. We use an age-stratified eight compartment epidemiological model to depict COVID-19 transmission in the community and within households. With a simulated 120-day outbreak period data we obtain a post 180-days period optimal control strategy solution. Our results show that easing social distancing between adults by the end of …
Lesson Plan - Cities As Systems, Center For Urban Resilience
Lesson Plan - Cities As Systems, Center For Urban Resilience
Module 01: Introduction to Urban Ecology
This lesson is designed to elicit student preconceptions about cities, introduce the idea of cities as systems, and introduce the driving question for the entire year. The lesson begins with a brainstorm where the teacher leads a “word splash” about the word city. Then in order to encourage students to start thinking of cities as systems, student groups draw up plans (or construct models) of city neighborhoods and work to fit these neighborhoods into a city. To understand the time aspect of systems (and cities), these student groups are provided with imaginary (but possible) events that happen to their constructed …

Lesson Plan - Ecosystem Structure, Center For Urban Resilience
Module 01: Introduction to Urban Ecology
This lesson was designed to complement instruction about the different categories of elements that make up an ecosystem: biotic, abiotic and man-made. Students will first categorize the things they pass on their way to and from school. Next, students will visit the field study site for the first time to familiarize themselves with the site, to understand that “nature” exists everywhere, and to experience the idea that humans—and their activities—are embedded in the environment and ecosystems.

Lesson Plan - Ecosystems And Change, Center For Urban Resilience
Module 01: Introduction to Urban Ecology
Students gain a deeper understanding of the process of change for an urban ecosystem in this lesson, including the aspect of time, what processes drive this change, and the ways in which scientists study change over time. The idea of sustainability is introduced in this lesson, and students are given the opportunity to learn about the sustainable practices of their own city, and to compare the sustainability of their field study site to the sustainability of their city as a whole.
