Curated OER
Fallout!
Students plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...
Curated OER
Air Pollution Over Where?
Young scholars predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

Science Buddies: Can You Change the Rate of a Chemical Reaction?
The ingredients in Alka-Seltzer tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces...
Texas Instruments
Texas Instruments: P H
Students use a pH sensor to measure the pH level of water in a stream or lake. They examine how air pollutants like sulphur dioxide, nitrogen oxides, and carbon dioxide cause acid rain, which affects the pH of water bodies and aquatic...
