An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using only a compass and straightedge. The method used involves constructing the perpendicular bisectors of two random chords. The bisectors intersect at the center of the circle. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This video introduces viewers to oceanic thermohaline circulation - the system of global ocean currents that cycle warm and cold water across the planet.

The weather is getting nicer, which means the flowers are blooming and calling a few animal friends their way. This Read & Seed lesson will focus on pollinators and their very important job. We will read Flowers are Calling by Rita Gray and Kenard Pak and create our own flower bookmarks. Participate in a Movement/Music/Finger Play activity by acting like our favorite pollinators. This lesson is aimed at connecting young learners to their natural world and promote school readiness skills. This Read & Seed activity is presented by The Gardens on Spring Creek by the City of Fort Collins. https://www.fcgov.com/gardens/files/read-seed-website-flower-bookmarks.pdf?1588609594

This interactive follows carbon as it moves through various components of the carbon cycle.

This video outlines background and goals of resilience with a focus on communities and climate resilience.

In this course, you will cover some of the most basic math applications, like decimals, percents, and even fractions. You will not only learn the theory behind these topics, but also how to apply these concepts to your life. You will learn some basic mathematical properties, such as the reflexive property, associative property, and others. The best part is that you most likely already know them, even if you did not know the proper mathematical terminology.

This lesson requires two class periods. In the first class period, students are asked to think of a way to decide who gets 100 pennies and how many each person gets. They learn about the concept of allocation and about different resource allocation methods. They evaluate the different methods using a graphic organizer. Next they listen to different scenarios and try to determine which allocation method was used. Then, after listening to the story Four Feet, Two Sandals about two girls who face some resource allocation issues, they identify the methods used in the story. In the second class period, the students are placed into groups to act out skits illustrating a resource allocation method that their classmates then try to guess. Finally, they read a news article about a resource and write letters to a city council outlining the ways the city could allocate the resource.

Scientific research relies on computer software, yet software is not always developed following practices that ensure its quality and sustainability. This manuscript does not aim to propose new software development best practices, but rather to provide simple recommendations that encourage the adoption of existing best practices. Software development best practices promote better quality software, and better quality software improves the reproducibility and reusability of research. These recommendations are designed around Open Source values, and provide practical suggestions that contribute to making research software and its source code more discoverable, reusable and transparent. This manuscript is aimed at developers, but also at organisations, projects, journals and funders that can increase the quality and sustainability of research software by encouraging the adoption of these recommendations.

This video segment, adapted from Need to Know, discusses how the process of hydraulic fracturing (fracking) is used to extract natural gas and how the process may be polluting water resources with hazardous chemicals, leading to health concerns.

Students work with data that represent the ages of 24 people to learn the difference between categorizing data in fractile intervals and equal intervals. Students discuss dividing bonus points among class members to understand what per capita means. Then students look at per capita personal income by state using the GeoFRED mapping tool. They compare per capita personal income displayed with data in equal intervals and with data in fractile intervals.

Freeland, CO Mining Town. Western Mining History presents a brief summary of Colorado's Historical Mining Towns with links to additional Colorado resources for a mining town database and mines by county. Western Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a strong primary source resource that can be used for a variety of class research projects. Consider becoming a member or making a donation to help further the work of the site.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

In this course, you will learn the basics of French, including reading, writing, listening, and speaking. At the end of the quarter you will know how to introduce yourself and volunteer basic information, and how to ask questions of others. You will also have some knowledge of French and Francophone cultures and protocols. This class is divided into four modules, which follow the chapters in the textbook. In each module you will be asked to read, write, speak, and listen in French. The class also includes a quarter-long cultural immersion project, in which you will be asked to conduct research on specific aspects of a non-European Francophone country and report your findings to the rest of the class.

Prepaid cards were invented to solve a problem: replacing coin usage in pay telephones. Since then, prepaid cards have evolved into a huge competitive market for general-purpose reloadable (GPR) prepaid cards. Read more about GPR prepaid cards in the May 2015 inaugural edition of Page One Economics Focus on Finance.

From the Ground Up is a collection of undergraduate writings on the interplay between health, the environment and community. The chapters range from engaging pieces on life during the Covid Lockdowns of 2020 to the environmental artist and food justice activist Ron Finley who is merging community, art and food security in South Central, Los Angeles. This work also includes an exceptional analysis of the haunting legacy of contaminated waterways in Brazil. The methods of analysis found within the collection include PhotoVoice and visual analysis—methods which have long been utilized within sociology, history, cultural studies, anthropology and community-based participatory research to achieve theories of resilience (via an analysis of community voices and community art forms) that literally emerge from the ground up.
