Teaching Materials
Positives
- Considering who stands to benefit from the spread of certain sentiments and information is a critical skill for navigating situations inside and outside of the classroom.
- Many questions are open-ended, allowing for nuanced classroom discussion.
Prerequisites
- It might help to introduce students to examples of current or past chemicals of concern, such as glyphosate, 2-4D, atrazine, PFAS/PFOAs, benzine, and organophosphate pesticides.
- Students should know how to cite evidence from a source to support their claims.
Differentiation & Implementation
- Art students can analyze the artistic elements present in the media examples and hypothesize the reasoning behind the design choices.
- After this lesson, teachers can have students apply the skill of considering the motive behind advertisements and endorsements to sponsored posts on social media platforms.
- After viewing the greenwashing book cover, students can play this game to view ads that may include examples of greenwashing and evaluate how these ads may influence their shopping choices.
- To expand on the examples of sacrifice zones and the concept of environmental justice, teachers can use this lesson to take a closer look at Louisiana's Cancer Alley.
- Teachers can connect this lesson to many of the UN Sustainable Development Goals, especially Goal 3, Good Health and Well-Being, and Goal 10, Reduced Inequalities.
