Brit introduces the polyalphabetic cipher, which creates a lighter fingerprint than the Caesar cipher. Created by Brit Cruise.

Students take a close look at truss structures, the geometric shapes that compose them, and the many variations seen in bridge designs in use every day. Through a guided worksheet, students draw assorted 2D and 3D polygon shapes and think through their forms and interior angles (mental “testing”) before and after load conditions are applied. They see how engineers add structural members to polygon shapes to support them under compression and tension, and how triangles provide the strongest elemental shape. A PowerPoint® presentation is provided. This lesson prepares students for two associated activities that continue the series on polygons and trusses.

During this activity students will learn how to estimate population size using two techniques, density extrapolation and the mark-recapture method.

Social distancing can be tough, and we are all in need of a little positivity! This week’s virtual Read & Seed will help us transform our neighborhood into that of something beautiful. We will read Maybe Something Beautiful: How Art Transformed a Neighborhood by F. Isabel Campoy, Theresa Howell, and Rafael López and create our own positivity posters with nature as our inspiration. We will also participate in a Movement/Music/Finger Play activity by singing The More We Get Together. 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://youtu.be/qaKv_ozqklo

Learn what the futures of the Eastern Shoshone and Northern Arapaho tribes are, and how the tribes will retain their culture and tradition while preparing to move into the future? In the accompanying lesson plan (found in the Support Materials) students will understand the importance of education and perservation of the culture.

Students will discuss the development of Indian boarding schools in the United States and Wyoming.
Students will analyze the differences between the early educational experiences of the Native American and non-native students.
Students will examine the importance of education as a value that the Shoshone, Arapaho, and non-native communities share.
Students will consider how Native American students and non-native students can learn from each other to dispel the myths and stereotypes that exist in contemporary society.
Students will learn why oral traditions are important.

Students will discuss the relationship that Native American people have with the buffalo (i.e., spiritual, sustenance, etc.) and how oral traditions play a critical role in the preservation of Native ways of knowing.

The presidential election of 1824 represents a watershed in American politics. The collapse of the Federalist Party and the illness of the "official candidate" of the Democratic-Republicans led to a slate of candidates who were all Democratic-Republicans. This led to the end of the Congressional Caucus system for nominating candidates, and eventually, the development of a new two-party system in the United States. In this unit, students will read an account of the election from the Journal of the House of Representatives, analyze archival campaign materials, and use an interactive online activity to develop a better understanding of the election of 1824 and its significance.

Remember when airlines started charging for checked bags? What happened to the number of checked bags after this added charge? And what happened to the availability of in-cabin storage space on planes? The April 2013 issue answers these questions and discusses the pivotal role price plays in a market economy.

Students develop the production possibilities frontier model while discussing the value of models in general in explaining complex ideas. They see what movement along the production possibilities curve entails on both the constant-cost curve and a bowed curve indicating increasing costs. They discuss ways a society can consume beyond the limits of its production possibilities through specialization and trade, as well as through an increase in resources, capital investment, and technological advance.

Are many products made in the United States anymore? As it turns out, yes. In fact, U.S. manufacturing output is near its highest level ever—and with fewer workers. How is that possible? Productivity growth. The March 2017 issue of Page One Economics describes what affects productivity, why economists are concerned about its recent slowdown, and what can be done about it.
