Task students with this data analysis of real NO2 levels
This activity presents students with real data on the levels of NO2. You can use the data in an open-ended goal free problem or use the questions in the downloadable worksheet to guide students through an analysis. It prompts students to look at calculations of mean and range, and representing data in graphs and charts.
You might find it useful to read, and share with students, the accompanying article from Education in Chemistry, How do trees clean our air?
