Introductory course on American Government, designed also to prepare for the College Board's CLEP subject matter exam.

presents a travel itinerary of 58 historic places across Arizona, Colorado, and New Mexico. It includes forts built to protect mail routes and settlers, missions and churches, prehistoric cliff dwellings, trading posts, petroglyphs (from the petrified forest), pit house villages, and Indian villages home to the Anasazi, Sinagua, Zuni, and other Native American tribes.

Having students follow animal tracks (even just people, dogs, or squirrels) and investigating how tracks are made is a fun and exciting way to develop critical thinking, measurement, and graphing skills.

In this lesson, students explore the importance of albedo (or reflectivity) to penguins and the surfaces they inhabit and learn how penguin colonies may be mapped using satellites.

This collection was inspired by Ellen Wolpert's article about anti-bias work with younger students. Her article suggests that teachers should keep a collection of non-stereotypical photos of people doing regular things that can be referenced to stimulate class discussion or address biased language with young children.

The photos in this growing collection are organized into (Google Drive) folders inspired by categories mentioned by Ms. Wolpert: Race, Age, Physical Abilities, Gender Roles, Families/Sexual Orientation, Jobs, and Ethnicity. Each folder contains different photographs curated from various Creative Commons websites, including Unsplash, Pixabay, and Pexels. Currently there are 80 photographs in the collection. They have been assembled here for your convenience and represent many hours of searching, downloading, and editing.

This lesson sequence guides students to learn about the geography and the unique characteristics of the Arctic, including vegetation, and people who live there. Students use Google Earth to explore the Arctic and learn about meteorological observations in the Arctic, including collecting their own data in hands-on experiments. This is the first part of a three-part curriculum about Arctic climate.

In this jigsaw activity, students explore meteorological data collected from Eureka, Canada to try to decide when would be the best time for an Arctic visit.

In this activity, students use authentic Arctic climate data to unravel some causes and effects related to the seasonal melting of the snowpack and to further understand albedo.

In this middle school and high school unit, students engage with 360° virtual reality tours, authentic Arctic datasets, and app-based labs to construct models and explanations for the unit driving question, "Why might the Arctic be warming twice as fast as the rest of the world?"

In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.

In this lesson, students investigate whether other parts of the world are changing and getting hotter just like Colorado.

Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!

This simulation gives students the opportunity to explore both area and perimeter of 2-dimensional shapes. Students can explore by creating shapes and having the sim calculate the area and perimeter. They can also play a game where the goal is to create a shape with a specified area or area and perimeter, or to calculate the area and/or perimeter of a given shape.

Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying algebraic expressions. Use the game screen to test your multiplication and factoring skills!

Build rectangles of various sizes and relate multiplication to area. Partition a rectangle into two areas to discover the distributive property.

Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying large numbers. Use the game screen to test your problem solving strategies!

This activity helps students learn to be open-minded and to participate in respectful discussion using evidence and reasoning. These are great life skills that any citizen of the world should have. They’re also scientific argumentation skills. The ability to change one’s mind based on evidence and reasoning, to see issues as complex, and to look at issues and claims from different perspectives are all scientific argumentation skills. Students also learn that absolute answers rarely exist. These skills and understandings are useful beyond science for anyone interested in figuring things out and in talking with others about issues, particularly with those who have different perspectives and opinions.
