Ocean Acidification in a General Chemistry Laboratory Experiment: Scientific Data and Indigenous Knowledge
Jessica Pikul, North Seattle College
Students explore the effects of ocean acidification by measuring the mass loss in seashells and the calcium ion concentration in seawater. Alongside data collection during a series of laboratory sessions, students learn about the disproportionate effects of ocean acidification on indigenous livelihoods, food security, and cultural practices, as well as how indigenous knowledge and practices can be used to address acidification locally. The activity ends with students composing an email to an elected official in which they express their opinion about the issue using claim–evidence–reasoning formatting.

Studying the Social/Cultural, Environmental, and Economic Impacts of Flooding on Chehalis River Basin Communities in a Geology Course
Michelle Harris, Centralia College
Students apply their knowledge of river processes, floodplains, and flooding to learn about, evaluate, and share flood mitigation strategies developed by governments and non-profit organizations in collaboration with local communities and tribal nations. Through strategy evaluation using social/cultural, environmental, and economic perspectives, students learn about the disproportionate impacts of floods and flood mitigation on marginalized communities near their college. Students conduct interviews to share information about sustainable flood mitigation strategies with community members who are affected by flooding and reflect on the effectiveness of their efforts.

Exploring Sea Level Rise in Algebra and Pre-Calculus: Learning About Affected Communities, Creating Mathematical Models, and Practicing Mathematical Communication Skills
Mathi Radhakrishnan, Bellevue College
Students begin this activity by learning how communities in Bangladesh are affected by melting glaciers and sea level rise, as well as why these phenomena are happening as a result of global climate change. They complete a modeling activity by collecting sea level height data from an interactive map, using linear regression to fit a mathematical model to the data, and reflecting on the accuracy of their model, as well as climate change models in general, by doing calculations with their regression equation. The activity ends when they present their models and have a conversation, with a person who is not a mathematician or familiar with mathematical models, about how models are sometimes misused to create an illusion of uncertainty about humankind's contribution to climate change.

Climate Justice, Life Expectancy, and Gender Disparities in Intermediate Algebra
Tatiana Mihaylova, Bellevue College
After an introduction to climate justice and life expectancy, students complete a two-part project. For the first part of the project, students use life expectancy data and plots using the Cartesian coordinate system to make conclusions about the impact of climate change on health and longevity and to explore gender differences. For the second part of the project, students continue to practice math skills, and also practice math communication and build their math literacy, by engaging civically through conversation about the first part of their project, as well as how they can take action to support gender equity through family planning and education for women and girls as a way to address climate change.

The Impacts of Climate Change on x̌əpayac (Western Redcedar) and the Social Justice Implications for Indigenous Culture
Kristen Harrison, Tacoma Community College
Students use botany to explore how cedar trees are affected by climate change and the cultural importance of these trees to local indigenous peoples. As part of a field-based laboratory experience, students participate in a citizen science project that involves collecting data about cedar trees. The activity ends with a civic engagement experience designed and carried out by students to demonstrate how scientists can share their work with the public and with policymakers to address issues of concern to society.

Climate Justice and Health Impacts of Methane (so-called Natural Gas) in General or Introductory Chemistry
Heather Price, North Seattle College
In this activity, students explore the chemical forms of methane (CH4), learn about the various sources and uses of methane, and gain knowledge of human health impacts and the disproportionate impact of extraction pollution on poor and racialized communities. They also connect the social justice impacts of methane to methane chemistry and exercises in the classroom.

Interdisciplinary Problem-Solving Project for the Science Classroom
Liliana Caughman
Students are assigned unique roles and work independently to solve a complex problem from the perspective of their role (i.e. sociologist, educator, historian, etc.) Students then work collaboratively to present their findings and action plan to the "tribal council".

Determining Energy Efficiency: A Lab Activity
Paul Frazey, Whatcom Community College
Students determine the energy efficiency of different methods of heating substances in the lab and then assess the economic and environmental costs.

Migration: An Empathy Exercise
Maureen Ryan, Western Washington University
Migration: An Empathy Exercise is a multi-step reflective exercise designed to build empathy and personal insight into processes of loss, change, and reconnection associated with the disruption of personal and cultural connections to landscape.

An Assessment of Riparian Vegetation in a Human-Influenced Landscape
Lisa Carlson, Centralia College
Given that humans historically have heavily used rivers and the lands along them for agriculture, transportation and other activities, how does human impact currently affect riparian ecosystems in a rural region? Students will address this question through several activities.
