Houston is home to 22 bayou systems. They were here long before we were. For centuries they carried water safely to the Gulf. Then we paved over them and wondered why the city flooded. The bayous have a lot to teach us.

Houston is a city shaped by water, built on bayous, and surrounded by one of the largest petrochemical complexes in the world. This module explores the natural systems that define our city — and the challenges they face.
Objectives: Understand Houston's 22 bayou systems, Know why Houston's terrain makes it flood-prone, Recognize the scale of petrochemical industry along the Ship Channel, Understand how development affects natural drainage
In 1990, Houston averaged 7 days above 97 degrees each year. By 2050, that number is projected to hit 49. The climate is not changing somewhere else. It is changing here.
— ClimateCheck / Climate Impact Assessment for Houston
Houston is already feeling the effects of a changing climate. Stronger hurricanes, longer heat waves, and rising seas are not future problems — they are happening now. This module explains what the science says about Houston's future.
Objectives: Understand how climate change intensifies hurricanes, Know Houston's projected temperature increases, Recognize the threat of sea level rise to the Gulf Coast, Connect local weather experiences to global patterns
Children who live within two miles of the Houston Ship Channel have a 56 percent higher incidence of leukemia. Your ZIP code should not be a death sentence. Environmental justice means everyone deserves clean air — no matter where they live.

Not everyone in Houston breathes the same air. Communities along the Ship Channel — mostly Black, Latino, and low-income families — live next to refineries and chemical plants. This module explores why where you live should not determine how long you live.
Objectives: Define environmental justice and its relevance to Houston, Know what fenceline communities are, Understand how segregation created sacrifice zones, Recognize health impacts of industrial pollution, Learn about EJ organizations in Houston
The most important thing you can do about climate change is something you already know how to do: talk about it. Not with facts and figures. With your heart. Talk about what you love and why it is worth protecting.

You do not have to be a scientist or a politician to make a difference. This module shows you everyday actions, advocacy opportunities, and growing career paths in conservation and clean energy — right here in Houston.
Objectives: Identify practical conservation actions, Understand how to advocate for environmental policy, Know about green job opportunities, Find local organizations to volunteer with, Recognize that talking about climate change is itself powerful
When Hurricane Harvey dropped 27 trillion gallons of water on Houston, the first responders were not all in uniforms. They were neighbors with boats. Strangers with dry blankets. Resilience is not a building. It is a relationship.

Houston has survived hurricanes, floods, freezes, and more. What gets us through is not just infrastructure — it is each other. This module explores how neighborhoods prepare together, support each other during disasters, and build lasting networks of mutual aid.
Objectives: Understand what community resilience means, Create a household emergency plan, Learn about Houston's Resilience Hub network, Understand mutual aid principles, Find neighborhood disaster preparedness resources
