History holds many economic lessons. The Great Depression, in particular, is an event that provides the opportunity to teach and learn a great deal about economics-whether you're studying the economic reasons that the Depression took place, the factors that helped it come to an end or the impact on Americans who lived through it. This curriculum is designed to provide teachers with economic lessons that they can share with their students to help them understand this significant experience in U.S. history.

In this course, superhero Jack of All Trades and his sidekick Andy are confronted by a villain that threatens to disrupt society and rob the world of the certainty people have come to expect. And this dastardly villain is...Inflation. Jack and Andy time travel to the period known as The Great Inflation to discover the truth about inflation. With the help of Dr. Equilibrium, professor of economics, they learn that inflation is the result of too much money chasing too few goods and that the Federal Reserve System plays a key role in maintaining stable prices.

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

In this short video, atmospheric scientist Scott Denning gives a candid and entertaining explanation of how greenhouse gases in Earth's atmosphere warm our planet.

Grenzenlos Deutsch is a no-cost alternative to textbooks. We seek to represent a breadth of perspectives that will enable our students to talk about their own lives; thus we have designed content that is actively feminist, anti-racist, anti-classist, anti-ableist, LGBTQIA+ friendly and represents a spectrum of experience.

For each of the thematic modules, there are three units of increasing complexity. Each unit has approximately six lessons, and each lesson has an Erweiterung, which includes additional activities to recap and solidify activities in the main lesson; they were designed to be used as homework or in additional hours (for example, in a lab or conversation session).

Visit https://grenzenlos-deutsch.com/ for the full curriculum.

Grenzenlos Deutsch (GD) is:

Interactive: The activities are intended to give you opportunities to practice some of the skills you’ll be learning along the way.
Cultural: Each lesson includes readings and/or video that relates to some aspect of DACHL culture (D- Germany; A- Austria; CH- Switzerland; L-Liechtenstein).
Inclusive: One of our goals is to make it possible for you to talk about yourself and your life in German, and thus we introduce basic language for talking about LGBTQIA+ identities, complex family structures, and lifestyle choices such as veganism, vegetarianism, and intentional communities.

A rubric designed by the Grossmont Unified High School District to be used when assessing the quality of resources.

In spring 2020, the world was hit by a pandemic that spread globally by March, causing universities and most of the world to move to remote means. Summer field camps, long hailed as a rite of passage in the geosciences, were cancelled throughout the US. The community moved quickly, with NAGT developing remote learning tools and arranging for sharing and collaboration between instructors and institutions. As such, UNAVCO (GETSI) and University of Northern Colorado embarked on a data collection campaign for a summer field course entitled "Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes" -- originally slated for in-person teaching. The team collected GNSS data, drone imagery for use in structure from motion, and terrestrial laser scanning from a site near Greeley, Colorado on the Poudre River. This assignment uses real-time kinematic GNSS methods to establish a ground control points used in Sheep Draw Structure from motion activity.
Day 3 Part 1 - This activity is part of the 2-week remote field course Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes

For this activity, students will first complete a mindset assessment to learn about their current mindset. Next, students will review the videos and the attached article entitled "Building Growth Mindset" and answer the four questions posed by Bradley Busch in the article.

Did you know that honey bees dance? Or that they build their homes out of perfectly formed honeycomb? The Digital Hive Experience was created to educate about the inside of a beehive and our friends, the honey bees. Pair the Digital Hive Video with the companion Educator’s Guide! Included are a lesson plan mapped to the Common Core and NGSS, pre and post-assessments, discussion questions, and a KWL Chart for your students! Perfect for a classroom introduction or for programs that may not have live bees, we hope you enjoy your journey into the hive!

In this lesson, students analyze and synthesize data about how drought is measured, how scientists expect drought to change in the future, and how we can mitigate the impacts of drought in our communities.

In this lesson, students build an understanding of drought in Colorado through exploring case studies, authentic data, and online resources. After completing this lesson, students will be able to understand the basic causes and impacts of droughts, analyze a case study and current drought data in Colorado, and summarize the main preparedness steps and response strategies for drought events.

In this lesson, students analyze and synthesize data, and design local flood preparation strategies to answer the question, "What can we learn from past flood events to prepare for future floods?"

In this hazard lesson, students build an understanding of flooding in Colorado by exploring case studies, authentic data, and online resources. After completing this lesson, students will be able to understand the basic causes and impacts of floods, analyze case study and current flood data in Colorado, and summarize the main preparedness steps and response strategies for flood events.
