Evaluate low level ozone pollution in your own state and compare it with other areas to see if you should be concerned about the air you are breathing.
Find out what sources are contributing to the particulate pollution in your state. An interactive bar graph shows the major types of air pollution and their sources. This particular activity focuses on two types of particulates.
In this activity, you will monitor the levels of ozone in Trenton, New Jersey for several days and make final decisions about the influence of weather on ground level ozone.
In this video segment adapted from ZOOM, cast members make their own hovercraft and demonstrate how the air leaking out of a balloon can make a plastic plate hover above a table. Experiment instructions are also available in a PDF document. [3:31]
This narrated lesson explains how Newton's second law of motion changes when air resistance is considered with falling objects. [6:42]
