Environmental JusticeActivities & Teaching Strategies
Active learning works especially well for environmental justice because it transforms abstract data and distant history into visible, concrete patterns that students can explore themselves. When students manipulate GIS tools or analyze real community stories, they move from passive acceptance of textbook claims to active evidence gathering.
Learning Objectives
- 1Analyze spatial data from EPA's EJScreen to identify communities with disproportionately high environmental burdens.
- 2Explain the historical and social factors, such as redlining and zoning laws, that contribute to environmental injustice.
- 3Evaluate the effectiveness of current policies aimed at promoting environmental equity.
- 4Design a community-based strategy to address a specific environmental justice issue in their local area.
- 5Compare environmental quality indicators across different demographic groups within a chosen city or region.

Map Investigation: EJScreen Analysis
Students access the EPA's EJScreen tool and search their own zip code or a teacher-provided urban area. They record the environmental justice index values, identify which demographic groups bear the highest environmental burden in that area, and discuss what geographic and historical factors might explain the pattern they find in the data.
Prepare & details
Analyze how environmental hazards disproportionately affect marginalized communities.
Facilitation Tip: During the Map Investigation, have students zoom into their own state or city first so they see familiar places in the data before tackling larger regions.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Case Study Investigation: Three Environmental Justice Battles
Small groups each research one landmark environmental justice case such as the Flint water crisis, Cancer Alley in Louisiana, the Dakota Access Pipeline dispute, or environmental health conditions in Richmond, CA. Each group presents the geographic location, the hazard, the affected community, and the outcome of any advocacy or legal efforts.
Prepare & details
Explain the social and economic factors contributing to environmental injustice.
Facilitation Tip: For the Case Study Investigation, assign each group a different battle and require them to present a 2-minute 'timeline' of key decisions that led to the injustice.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Think-Pair-Share: Who Bears the Climate Burden?
Students examine a map showing global CO2 emissions per capita alongside a map of countries most vulnerable to climate impacts including flooding, drought, and sea-level rise. They discuss the mismatch between who causes climate change and who suffers most from it, then extend this analysis to environmental justice patterns within U.S. cities.
Prepare & details
Design strategies to promote environmental equity in local and global contexts.
Facilitation Tip: During the Think-Pair-Share, provide sentence stems like 'One community bears more risk because...' to guide precise academic language.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Solution Design Workshop: Environmental Equity in Our Community
Groups identify one environmental hazard disproportionately affecting a specific local or regional community and design a policy or community-organizing strategy to address it. Proposals are evaluated against criteria of feasibility, equity, and geographic reach. Groups present their plans to the class acting as a community review board.
Prepare & details
Analyze how environmental hazards disproportionately affect marginalized communities.
Facilitation Tip: In the Solution Design Workshop, give students a budget limit and require them to justify every expense using evidence from their maps and case studies.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Teaching This Topic
Teach environmental justice by making students confront the uncomfortable truth that spatial inequality is not random but engineered through policy. Use GIS tools to let students uncover these patterns themselves, which research shows deepens understanding more than lectures. Avoid framing this as a debate about whether injustice exists; focus instead on how to measure and remedy it. Draw on local examples whenever possible to make the issue feel immediate rather than distant.
What to Expect
Successful learning looks like students using spatial data and historical evidence to explain why environmental burdens cluster in specific communities rather than spreading evenly. They should connect policy decisions to present-day maps and propose concrete solutions based on their analysis.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Map Investigation, watch for students who assume the data shows random distribution of pollution sources.
What to Teach Instead
Use the EJScreen tool to have students overlay multiple layers (demographic data, pollution sources, flood risk) and specifically highlight how these layers overlap in specific communities rather than spreading evenly.
Common MisconceptionDuring the Case Study Investigation, watch for students who claim environmental injustice is accidental or unavoidable.
What to Teach Instead
Have students trace the historical policy decisions (redlining maps, highway routes) on modern case study maps to show how these choices concentrated environmental burdens in communities of color.
Common MisconceptionDuring the Think-Pair-Share, watch for students who limit environmental justice to toxic waste sites only.
What to Teach Instead
Ask students to map green space distribution alongside demographic data, then have them calculate tree canopy coverage per neighborhood to reveal disparities in heat exposure and health risks.
Assessment Ideas
After the Case Study Investigation, ask students to share their findings and respond to: 'Which historical decision do you think created the most lasting environmental injustice, and what evidence from your case study supports this?' Listen for connections between policy choices and present-day burdens.
During the Map Investigation, provide students with a local map and ask them to identify one environmental burden and one demographic characteristic for two neighborhoods, then write a sentence explaining if they see a potential environmental justice issue.
After the Solution Design Workshop, ask students to write down one environmental burden and one benefit, then describe a scenario where these are unequally distributed between two communities with different socioeconomic characteristics.
Extensions & Scaffolding
- Challenge students who finish early to design a public awareness campaign using the data they collected during the Solution Design Workshop.
- Scaffolding: Provide pre-highlighted maps and simplified case studies for students who struggle with complex texts or data interpretation.
- Deeper exploration: Have students interview a local community member about environmental challenges in their neighborhood and compare findings to official EPA data from EJScreen.
Key Vocabulary
| Environmental Justice | The fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. |
| Environmental Burden | A negative environmental condition, such as pollution, toxic waste, or lack of green space, that negatively impacts the health and well-being of a community. |
| Redlining | A discriminatory practice where services, especially financial services like mortgages, are withheld from potential customers who reside in neighborhoods classified as 'high-risk,' often based on racial or ethnic composition. |
| Environmental Equity | The principle that all people should have access to a clean, healthy environment, and that no community should be disproportionately exposed to environmental hazards. |
| Disproportionate Impact | When a particular group of people experiences a significantly higher level of negative consequences from a policy, practice, or environmental condition compared to other groups. |
