Clean Air Trek

You breathe 28,000 times each day. That’s 3,000 gallons or 35 pounds of air every single day. Clean Air Trek is an exhibit about the air you breathe, the neighborhood you live in, and how to get the most out of your life.


  • Hybrid Vehicle: Is that a car up in that tree? Yes. It’s an early hybrid vehicle. We even took it apart so you could get a better look. Discover how battery and motor technology are transforming personal vehicles and cleaning the air.
  • Energy into Motion: Take an interactive look inside an internal combustion engine! See how spark plugs ignite gasoline and how pistons harness the energy of that explosion.
  • Catalytic Converter: How does a catalytic converter transform harmful emissions into relatively harmless exhaust? Explore the technology that has made the automobile much more air-friendly.
  • Air Quality Monitoring Station: What’s the air like today? Find out at the Air Quality Monitoring Station with real-time data from around the city. At this station you can also investigate a little atmospheric chemistry.
  • Your Neighborhood: What does your neighborhood mean to you? It’s where you live. It’s the people around you.  Discover how you can change your neighborhood just by moving through it.
