A change in climate over time has contributed to a significant increase of wildfires in our state. In this storyline, students will make the connection between changes in ecosystems and the interconnectedness of all things. Students will gain an understanding of combustion (fire triangle), and observe through data that certain conditions (humidity, temperature, fuel load, etc.) contribute to forest fires (fire environment triangle).

What we see on Earth’s surface is a complex and dynamic set of interconnected systems that include the geosphere, hydrosphere, atmosphere, cryosphere and biosphere. Earth’s processes are the result of energy flow and matter cycling within and among these systems. Understanding Earth’s systems is important for many decisions made in communities today such as where to build a road, where a salmon can successfully build a redd to lay eggs, and how to ensure air quality. Erosion involves all five spheres giving students an excellent example of the interconnectedness of these large systems. Students may begin the storyline by hearing a story about the relationship between the land and plants from an Indigenous perspective, a local tribe elder or expert if possible. This perspective can be woven throughout the storyline while students explore different types of erosion: wind, water and ice in sand and soil. For real life experiences, students visit their schoolyard or nearby area to find examples of erosion. They may find examples from very small to larger examples of places where soil has eroded. They may find places where human foot traffic has made pathways through a previously planted area.

The goal of the fifth grade Forests: Forest Ecosystem Benefits storyline is to build on students’ previous knowledge of plant/animal needs, ecosystems, and protection of Earth’s resources. In this storyline students develop an understanding of forest ecosystems, tree benefits including carbon sequestration, and what trees need to grow/gain mass.

While food waste is not typically seen as contributing to greenhouse gas emissions, it is a major contributor. Reducing food waste ranks as the 3rd most beneficial drawdown solution. Wasted food, and the resources to produce that food, are responsible for approximately 8% of global greenhouse gas emissions. When individuals and groups reduce food waste, it has a huge impact on reducing greenhouse gas emissions. Food waste awareness is applicable to every person and community. In this storyline, students connect with cultural values around food, impacts of food waste and solutions to food waste issues.
