The Story of 13 Moons: Developing an Environmental Health and Sustainability Curriculum Founded on Indigenous First Foods and Technologies

The Swinomish Indian Tribal Community developed an informal environmental health and sustainability (EHS) curriculum based on Swinomish beliefs and practices. EHS programs developed and implemented by Indigenous communities are extremely scarce. The mainstream view of EHS does not do justice to how many Indigenous peoples define EHS as reciprocal relationships between people, nonhuman beings, homelands, air, and waters. The curriculum provides an alternative informal educational platform for teaching science, technology, engineering, art, and mathematics (STEAM) using identification, harvest, and preparation activities of First Foods and medicines that are important to community members in order to increase awareness and understanding of local EHS issues. The curriculum, called 13 Moons, is founded on a set of guiding principles which may be useful for other Indigenous communities seeking to develop their own curricula.


Introduction
Our health comes from our culture, and our culture comes from our homelands... We have to take care of Mother Earth because there are uses for just about every bit of or environment. But you have to learn how to use it and you can only do that if you're there, listening. You can't get this from a couch, sitting there watching television.
-wanaseah Larry Campbell, Swinomish Elder Indigenous peoples are disproportionately impacted by environmental exposures and health disparities [1][2][3]. The salient impacts are widely recognized within communities and as such are considered high priorities to address [4,5]. Yet a serious disconnect exists between environmental and health agencies and Indigenous communities on how to define and operationalize environmental health and sustainability (EHS). In this paper, and via the stories of Swinomish Elders and leaders, we recount how the Swinomish Indian Tribal Community defines, addresses, and passes on knowledge about environmental health and sustainability.
In the mainstream science paradigm, environmental health (EH) is defined by individual impacts to human health from the food we eat, the water we drink, and the air we breathe [6]. The mainstream We take care of the fish and the water and they take care of us. We will continue to have ceremonies with fish even if they are contaminated. Like we say, it's our spiritual food so it feeds our soul; so it might poison our body, but then we'd rather nourish our soul [16].
To illustrate why conventional EHS education and intervention practices such as fish consumption advisories fail, we will talk about our experiences as staff and community members of the Swinomish Indian Tribal Community. The Swinomish Indian Tribal Community (Swinomish) is a federally recognized Indian Tribe organized under Section 16 of the Indian Reorganization Act. Today there are nearly 1000 enrolled members. The Swinomish Reservation is located on the southeastern end of Fidalgo Island in Washington State, USA. The Reservation was established by Article 2 of the Point Elliott Treaty between the federal government and Puget Sound Coast Salish communities in 1855. The current Reservation includes approximately 10,800 acres of upland area and approximately 4500 acres of wet and filled tidelands; most of the Reservation is ringed by saltwater ( Figure 1). The Swinomish have been a hunting, fishing, and gathering people since time immemorial. Harvesting, preparing, and using First Foods, medicines, and resources (also called traditional foods, or "our foods" by community members) is an integral part of the social and cultural fabric in the Swinomish community. Figure 2 illustrates the Swinomish definition of EHS. The image depicts 6 key aspects of Swinomish EHS (called Indigenous Health Indicators) in a scene where families are working together beach seining (fishing with nets from the beach), steaming shellfish in a fire pit, and crab fishing. Here, elders can be seen telling stories to Swinomish youth. Younger generations are exploring the beach and surrounding area, and learning how to harvest, cook, and preserve the catch. This image shows Swinomish people Sustainability 2020, 12, 8913 3 of 15 asserting their sovereignty by being on the land and water and engaging with natural resources that are abundant and accessible. In sum, the image depicts Swinomish people engaging in culturally important practices, which 'feed the body and the spirit' in the Swinomish way [17,18]. This clearly reflects the central importance of First Foods to Swinomish health and wellbeing broadly, and EHS specifically. First Foods can be thought of as cultural keystone species-foods that nourish the body and the spirit of both the individual and the community, while providing opportunities to pass on Indigenous knowledge about connections with nonhuman beings and the environment to the next generations [19]. Therefore, an Indigenous EHS education program taught through the lens of First Foods is a logical and natural coupling.  Figure 2 illustrates the Swinomish definition of EHS.

Therefore, an Indigenous EHS education program taught through the lens of First Foods is a logical and natural coupling.  In the remainder of this paper, we describe the development of an EHS education curriculum based on Swinomish beliefs and practices around First Foods. The curriculum objectives are to: increase awareness and understanding of local EHS issues among all ages of Swinomish community members; provide an informal (outside of school) educational platform for teaching science, technology, Sustainability 2020, 12, 8913 4 of 15 engineering, art, and mathematics (STEAM); and increase interest in healthy lifestyles and practices. We developed a set of guiding principles for the curriculum, which may be useful for other Indigenous communities wishing to develop their own curricula.

Materials and Methods
Our multi-generational curriculum development and implementation team consisted of Swinomish staff members, a Swinomish elder, a Northwest Indian College student, an EH researcher from Oregon State University, and a First Foods expert. In addition, an external advisory group of Indigenous EHS, education, and foods experts provided oversight and review of the draft curriculum. We founded the curriculum on existing Swinomish cultural frameworks, community structures, and existing community knowledge [20], to ensure lesson plans and learning methods are culturally appropriate [10,[21][22][23][24][25].
To identify existing Indigenous EHS resources, we evaluated peer-reviewed literature, grey literature, conference proceedings, and personal recommendations. Search terms included the following: Indigenous/Tribal/Native education plus environmental, environmental health, food, nutrition, or First Foods; Indigenous curricula/curriculum; Indigenous K-12 and/or education; and traditional/First Foods curriculum/education. We used the following criteria for inclusion in the list: the resource must describe a curriculum (formal or informal), exhibit, or program (science camp, museum exhibit); the resource must be specific to Indigenous populations; and resources are specific to North America.
A thematic analysis identified guiding principles. The analysis included recommendations from culturally based science education [21][22][23]26,27], review of research and curriculum implementation notes, insights from our collated resources, and input from Tribal elders. The project team agreed on eight guiding principles, which formed the curriculum framework for developing activities.
We used an asset-based approach and free-choice learning methods to develop the curriculum. Asset-based approaches to education are more successful than deficit-based approaches as they recognize cultural knowledge sources and community strengths [28,29]. Culturally based education promotes the inclusion of cultural assets, such as native languages, traditional and cultural practices, and community-based oral history and ways of knowing [10,26]. The focus on these assets changes the orientation of the educational program from a Western perspective to an Indigenous perspective [29,30]. Free-choice learning is self-motivated learning taking place outside of a formal classroom setting. When developed and implemented through a culturally based approach, free-choice science learning outside the school system resonates with how Indigenous communities have been passing on knowledge about their environments for millennia.
The curriculum underwent multiple iterations of evaluation: internal review; Swinomish community review; external review with the advisory committee of Indigenous EHS, education and foods experts, an independent Indigenous evaluation team; and review by the Swinomish Health, Education and Social Services Committee prior to publication. Working with an independent Indigenous evaluation team, we identified and incorporated the following outcomes into the overall evaluation. The 13 Moons program was designed to increase: opportunities for informal EHS learning through a cultural lens; awareness and understanding of EHS in the Swinomish community; understanding of a healthy community that encompasses physical, mental, spiritual, and environmental health; interest or motivation to implement healthy lifestyles, traditional practices, and harvesting; youth interest and engagement with elders, traditional practices; and youth interest in STEAM fields and careers.

Results
We identified 60 curricula and resources ( Figure 3). The curricula are predominantly subject-specific. For example, the Air Toxics under the North Star [12] curriculum focuses on indoor air. There were several environmental curricula [11,31,32]. A full list is available (see Appendix A). Taken together, all resources fall under the umbrella of EHS, albeit to varying degrees. We did not identify curricula that provided a comprehensive Indigenous EHS overview of the complex interplay between humans, nonhuman beings, and their environments.

We named the curriculum "13 Moons," which signifies the traditional Swinomish harvest calendar. Each moon is named for an important seasonal event or harvest that takes place during that moon [33]. We designed 2-3 activities per moon that utilize a plant and an animal species (Table 1). The curriculum is designed to encourage scaffolding of knowledge; students will learn about ironwood in the spring, and then use ironwood tools to weave cattail mats in the early autumn, which are then used during community dinners during the winter season. This continuity speaks to the repetition and integration built into 13 Moons. Each activity includes a complete lesson plan which includes: background on the food, medicine, or technology; learning objectives; time to complete the activity; target age group (activities are designed to span from pre-Kindergarten to elders); materials needed; words to learn in the Swinomish language (Lushootseed), knowledge transfer goals (from elders to youth); guiding questions for discussion; identification of environmental health connections; optional additional activities; and a citation and resource list. In the four years since we began in 2016, we have piloted many, but not all, of the activities.

An external Indigenous evaluation team reviewed the curriculum based on stated project outcomes. Overall, participant feedback indicated that the program is successful [34]. The evaluation identified several foundational strategies that contributed to success, namely: the program built off existing activities (e.g., annual celebrations, Swinomish youth program, Earth day, community dinners); Swinomish community members and elders were involved in the design and implementation of activities; and community assets and resources were the focus of all activities. Swinomish community members supported the program, as they felt it sustained healthy cultural practices, promoted intergenerational learning, and increased community connection. As one community member explained, the 13 Moons activities created a place and space for learning: "People started to speak out about what they were taught; so I think that it's bringing knowledge together, it's bringing teachings, and it's bringing community thoughts together on what they were told, on what their grandparents told them." Another community member noted, "As a Native people, we eat together, we gather together, it's that sense of learning together that brings a traditional aspect . . . it's a familiar setting for me" [34]. community member explained, the 13 Moons activities created a place and space for learning: "People started to speak out about what they were taught; so I think that it's bringing knowledge together, it's bringing teachings, and it's bringing community thoughts together on what they were told, on what their grandparents told them."

Discussion
We designed the Swinomish 13 Moons curriculum to overcome environmental, cultural, and literacy barriers in EHS programming [10,[35][36][37][38][39]. We found the approach successful within the Swinomish community, with the most common feedback being requests for more activities. The local school district has requested use of the curriculum, and other Indigenous communities have expressed interest in tailoring the curriculum for their own use. Due to the seasonality of the program, not all proposed activities could be completed in the three-year pilot phase. Future work will evaluate the success of the entire 13 Moons curriculum.
A review of published guidelines indicates that culturally based education (CBE) should situate learning within the community and cultural framework, build the curriculum on a foundation of cultural practices, and value Indigenous knowledge alongside conventional knowledge [10,[21][22][23]26,27,40]. Specifically, Demmert and Towner (2003) published five CBE guidelines: (i) Culturally based indigenous language use; (ii) culturally based pedagogy; (iii) culturally based curriculum; (iv) culturally based patterns of participation in leadership and decision making and; (v) culturally based methods of assessing student performance [26,27]. In 13 Moons, the Lushootseed language is integrated into each activity and each activity is led or introduced by Swinomish elders and knowledge-keepers (elements i and iv). A culturally based pedagogy (element ii) is defined as one "that empowers students intellectually, socially, emotionally and politically using cultural references to impart knowledge, skills and attitudes" [41]. As such, culturally based pedagogy views success in

A culturally based pedagogy (element ii) is defined as one "that empowers students intellectually, socially, emotionally and politically using cultural references to impart knowledge, skills and attitudes" [41]. As such, culturally based pedagogy views success in the long term, focuses on cultural competency within the learner's own culture, and highlights the socio-cultural framework of their community [42,43]. With First Foods and the lunar cycle as a foundation (element iii), as well as place-based activities, the curriculum explains Swinomish history, traditions, and culture; success is not measured quantitatively but qualitatively as students combine their knowledge and work with elders and instructors to complete activities. Finally, we used Indigenous evaluation methodologies (element v). This approach allows a holistic evaluation of participant engagement, knowledge transfer, and satisfaction with the program. While the curriculum is Swinomish specific, other Indigenous communities may find success in EHS engagement via the eight guiding principles and tailoring the First Foods, medicines, and technologies activities to their own values and practices.

Conclusions
The Swinomish 13 Moons program was developed in response to a paucity of Indigenous environmental health and sustainability educational programs. Our program welcomes learners of all ages in an informal learning environment and highlights Swinomish culture, traditions, and concepts at the forefront. We grounded the entire curriculum in principles of culturally based education and identified additional guiding principles that represent Swinomish principles of teaching, resilience, and sustainability. The curriculum was developed by Swinomish, for Swinomish. In addition, we created the guiding principles as our own foundation, and we hope that they will help other Indigenous communities in their journeys to revitalize culture and language as foundations in their curricula. The concept of the seasonal round is shared by many Indigenous communities, and the focus on First Foods ensures that the content is culturally relevant. The adaptable module design also encourages Western educational programs to incorporate elements into formal or informal programs. Thus, the 13 Moons program demonstrates a highly relevant, culturally-based education program for learners of all ages that can be adapted by Indigenous communities throughout North America.
In closing, we share with you a quote that exemplifies how environmental health and sustainability is one integrated concept, from the Swinomish point of view: I fostered two teenagers... They were getting into a little bit of trouble. They wore the backwards hats and they got the Native pride, you know, "I'm Indian, I'm Indian." I said, "Well, you really want to show your people how to be Indian, here I'll show you." I just happened to be filleting fish, I had a lot of fish. And we filleted them and I made them help me . . . I said, " . . . this is how you want to be Indian is you provide food for your people. It's not standing on the corner with a Native pride hat acting tough. That's not Indian." The effect on them was just passing that on . . . the importance, and emphasis that we have to gather these foods, we have to provide these foods in the wintertime when we're putting food on the table for the [ceremonial] smokehouse.
