Protecting our water and finding solutions to prevent water pollution is a huge undertaking, but even small steps can make a big difference. Educating and inspiring our students to take action against water pollution will help protect this finite resource. SubjectToClimate has collected detailed lesson plans about water pollution that will inspire teachers and students to start green initiatives in their classrooms, schools, and communities. 

“Rivers have always been an important resource. They provide water for drinking, a means of transportation, a home for wildlife, and more. As human populations have increased, so has our impact on the water system and many rivers have become polluted as a result. Some pollutants enter rivers through the actions of individual people, like leaving trash on the ground. However, other pollutants come from larger problems like factory run-off or driving cars. It is important that we know where river pollution comes from so that we can work together toward cleaner rivers today and in the future. “  - Population

Who Polluted the River?

Grades: K, 1st, 2nd

Subjects: Science, Biology, Earth and Space Sciences, English Language Arts

Resource Types: Lesson Plan

In this innovative lesson from Population Education, teachers will lead students through an interactive story that illustrates how a river becomes polluted over time. As the teacher tells the story, students will act as different pollutants and add substances to a jar of water, offering a visual demonstration showing how the rivers are being polluted.  This well-structured lesson plan includes discussion questions, printable labels and name tags for the activity, and follow-up activities that will help students to take action in their communities.

Teachers will love this downloadable, step-by-step, easy-to-use lesson plan. The plan includes teaching objectives, a list of needed materials, instructions for the procedure, discussion questions, and a script for the interactive river story. Students will practice a variety of skills throughout this lesson, including critical thinking, observing, and understanding cause and effect. 

This lesson requires a little prep as teachers will need to print and cut out both the canister labels and the character name tags, and they will also need to gather materials for the activity before teaching the lesson.

After completing the river story activity and going through the discussion questions, have students journal about their experience and write down questions they have about the waterways in their own communities. The follow-up activities provide great ideas for organizing a field trip to a local wastewater treatment plant so that students can ask questions about local water pollution problems and discover what can be done to fix these issues.

Natural Gas: Water & Climate Impacts

Grades: 6th, 7th, 8th

Subjects: Science, Earth and Space Sciences, Health

Resource Types: Lesson Plan

In this Project Look Sharp activity, students decode an advertisement and a web page for messages about how natural gas extraction impacts freshwater resources. Students will use their critical thinking skills as they examine and decode information on natural gas extraction from Wikipedia, America's Natural Gas Alliance, and Food and Water Watch. 

This lesson plan includes a student handout that contains the three texts, a student worksheet, and a PowerPoint presentation. The main draw of this lesson is that it teaches students to evaluate the reliability of sources and helps them practice analyzing media messages.

The reading for this activity is a bit dense, so a structured reading process may help some students. There are different ways to use this resource, for example, students could compare the Wikipedia article from the resource with the current Wikipedia article and note the differences. Students can use their newfound skills to make public service announcements that teach their school or community about how to evaluate sources and look past media messaging to better understand the risks of natural gas extraction on freshwater sources.

Regenerating for the Next Gen

Grades: 6th, 7th, 8th, 9th, 10th, 11th, 12th

Subjects: Science, Biology, Earth and Space Sciences, Health

Resource Types: Lesson Plan

In this lesson plan by ACE, students will learn about factory farming, CAFOs (concentrated animal feeding operations), and regenerative agriculture. Students discover that most industrial farming and ranching methods pollute nearby bodies of water and contribute to climate change. The lesson culminates with suggestions for how to empower students to partner with local organizations that are already taking action to promote regenerative agriculture and keep local waterways clean and healthy.

This lesson plan provides a student worksheet, a teacher guide, a slide presentation, a case study, and an informative video. This lesson challenges students to think critically about global food production, livestock production, and the role agriculture plays in water pollution and climate change. The case study focuses on solutions that improve carbon storage and reduce emissions.

This is a great resource to tie into science lessons about the carbon cycle, deforestation, ethics, ecology, and the nitrogen cycle. Economics and social studies classes could research current government subsidies going to the agricultural sector and discuss how they could be redirected to support regenerative or organic agriculture to achieve a reduction in emissions and address climate change. After the discussion, have the students write an email to government officials explaining how they think government subsidies should be redirected.

How "Forever Chemicals" Polluted America's Water

Grades: 6th, 7th, 8th, 9th, 10th, 11th, 12th

Subjects: Science, Chemistry, Biology, Health

Resource Types: Video

In this video from VOX, students will learn about “forever chemicals” that pollute waterways and discover how widespread toxic pollutants are in America’s drinking water. The video also discusses the importance of adopting a precautionary principle that would make it mandatory for companies to review and seek approval for new products, chemicals, and chemical ingredients.  

Teachers can build a full lesson plan around this video. Start the lesson by asking students if they feel safe drinking water from the tap. Have them discuss their answers with a partner or small group before showing the first three chapters of the video. Ask students to reflect on the following questions and record their answers:

  • How does learning about forever chemicals in the Cape Fear River make you feel?
  • How did some of the citizens respond when they found out that their drinking water was contaminated? 
  • Do you think that forever chemicals are present in drinking water in other places? Why or why not?

Show the rest of the video and then ask students to make a list of possible solutions to the problem of forever chemicals in drinking water.  After the list is complete, ask students to consider how they could take action to stop forever chemicals from getting into drinking water. 

Students could investigate the companies that make forever chemicals. They could research the health risks of being exposed to those chemicals using information on the  FDA, CDC, OSHA, and NIH websites. Students could also research products that contain PFOA chemicals and look for types of water filters that might be able to filter them out of drinking water. After completing their research, have students think of a way to increase public awareness of the problem or contact government officials at the local or national level to demand the regulation of hazardous chemicals in drinking water.
