Student Videos About Air Pollution

ER (Special Victims Unit) | An emergency room team rescues several objects--a building, a plant, a fish, and a tire--that have been adversely impacted by emissions of sulfur oxides and nitrogen oxides. In the atmosphere, sulfur oxides can be converted to sulfuric acid and nitrogen oxides to nitric acid. Additionally, nitrogen oxides can react with volatile organic compounds to form ozone.


Vanilla Rose Tropical Delight v. Ion Man | Two superheroes wage an epic battle of air pollution. An air freshener, Vanilla Rose Tropical Delight, and an ionic air purifier, Ion Man, engage in hand-to-hand combat that results in the formation of toxic compounds. Emissions of alkenes and aromatic compounds from air fresheners can react with ozone that is generated by ionic air purifiers to form formaldehyde and related chemicals, some of which are thought to be carcinogenic.


Blacksburg 500 | Mike, Cally, David, and Lamya square off in a race to determine whose vehicle has the cleanest emissions. They compare a gasoline-electric hybrid, a biodiesel car, a fuel cell car, and a gas guzzling SUV. They discuss carbon dioxide (CO2), nitrogen oxides (NOx), hydrocarbons (HC), particulate matter (PM), and sulfur oxides (SOx). Who will win?


A Global Warming Carol | James falls asleep in class and is visited by specters (Dan and Ray) who teach him about the causes and effects of global climate change.


Greenhouse Gas Cops | Officer Bobby tracks down four greenhouse gases played by Paul and Phill--carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3)--near some of their typical sources. In addition to being a greenhouse gas, ozone also causes respiratory irritation and other health effects. However, ozone very high in the atmosphere is good because is protects us from UV radiation.


The Magic School Bus: Volcanic Air Pollution | Brynn, Holly, and Christina ride the magic school bus to exotic locales to learn about air pollutant emissions from volcanoes. They discuss sulfur dioxide (SO2) and ash, among other pollutants.


News Channel KPPM | News anchors Dale and Ben discuss the sources, composition, and effects of particulate matter (PM). A field reporter Kevin interviews a sailor whose ship emits a lot of PM. They end by reminding us of particulate control devices such as filters and electrostatic precipitators (ESPs).


Spidey Fights the Fish | In this awesome "claymation" music video, Spiderman goes through his day creating air pollution and falls victim to a giant fish. Rising carbon dioxide levels are increasing the acidity of oceans (lowering their pH) because carbon dioxide in the atmosphere dissolves into water and forms carbonic acid (H2CO3-). The carbonic acid dissociates into hydrogen (H+) and bicarbonate (HCO3-) ions.


To Catch a Polluter | Air pollution special agents Brenna and Russ set up an undercover operation to catch a "most wanted" violator John, who sells cars without pollution controls. They spew particulate matter (PM), which causes respiratory irritation, is associated with premature death, degrades visibility, and affects global climate.
