This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how the air quality around your school affects your lungs and breathing. You'll complete simple lung health tests and wear an activity monitor like a Fitbit while doing a normal PE or science lesson outdoors, so scientists can see how pollution in your playground impacts your body's response.
Many children with asthma have symptoms that get worse on days with high air pollution, but we don't fully understand exactly how this happens or how much activity in polluted air affects young lungs. This study will help doctors better protect children's respiratory health.

You'll visit your school's playground on two days for a total of about 4 hours. On each day, you'll have your height and weight measured, do a quick breathing test, and provide a nasal sample (a small squirt of salt water in your nose). Then you'll wear an activity monitor and take part in either a PE lesson or a science lesson outdoors — just like a normal school day — while researchers measure the air pollution around you. You'll repeat the breathing test and nasal sample right after the lesson and again the next day so doctors can see how your body responded.
