Grade 5 students at Saint Andrew’s School caught wind of startling air pollution statistics during their studies which inspired them to take action and make a difference in their community. With a little help from Upper School Math teacher, Jim Scheidegger, as well as a Stanford professor and COO of a company in Silicon Valley, Ashley Egbert, Eli Cornell, Keely McGahee, and David Capeti went to work on a groundbreaking project that measured air quality in Boca Raton.
The Robinson Nature Center is an 18-acre, publicly-owned nature center that hosts 420 groups every year in Maryland in their 23,000 ft2 platinum LEED-certified facility. It was founded in 2009 following the wishes of James and Anne Robinson--who had previously lived on the land. They now have a new activity, which features the PocketLab Air, called Air Quality Outreach.
First, what is particulate matter (PM)? Particulate matter is a mixture of solids and/or liquids suspended within the air. These solids and liquids are too small for the eye to see, however, if they're in a high enough concentration it will often look like a haze in the air. The particles that make it up can be anything from pollen and dust to even molecules of water. The number at the end (ex. the 10 in PM10) is the upper limit of the particles’ diameter. A size comparison produced by the US EPA can be seen below.
It is almost instinctive when you first get the PocketLab Air to breathe directly on it just to see what happens. As seen below, of the PocketLab Air's seven sensors, five of them detect changes from a direct human breath. These parameters are carbon dioxide, particulate matter, temperature, humidity, and pressure. The most interesting of these is the sharp rise in carbon dioxide which, as the most important greenhouse gas, brings about strong connections to the topic of climate change.
When it comes to climate change, there are many resources out there. However, most are designed for the public’s use worldwide and are often limited to one perspective; ignoring the arguments against climate change. The Teacher-Friendly Guide to Climate Change stands apart from these others in that it:
Focuses in on climate change impacts in the US

Forest fires are a common natural disaster within western North America and pose a serious risk to many communities both nearby due to direct danger of the fire, as well as far away in the form of air pollution. Currently, in many places, some form of government employee will be in charge of looking out for forest fires and once identified, satellites and computer programs can be used to track its progression and predict where the fire will spread and where the smoke cloud will go. This allows us to evacuate individuals who may be in danger and minimize loss of life.
