Teaching Materials
Positives
- Students can easily toggle layers on and off, making it easier to see data as needed.
- Each data site has an informative pop-up that provides additional information.
Prerequisites
- Students should understand what PFAS are and the risks they pose.
Differentiation & Implementation
- Either before or after students analyze the map, teachers can show this video to help contextualize PFAS and give an example of community action.
- To make connections to environmental justice and environmental racism, students can analyze this data in conjunction with demographic data for the communities surrounding contaminated sites.
- To make connections to climate change, teachers can discuss the impact of climate change on water supplies and emphasize the need for clean drinking water.
- Teachers can expand on this by digging deeper into the environmental impacts of the military. This video can help touch on some of the other environmental impacts.
Though the webpage does provide a brief description of PFAS and how these chemicals likely contaminated the area, additional discussion or resources may be needed depending on the students' background or the topic of the lesson. The information presented is accurate, and this resource is recommended for teaching.
