Features 13 core activities covering the fundamental topics of weather & climate, seismology & topography, soil properties and more.
Acid Rain and Weathering
Use a pH sensor to test a simulated acid rain’s reaction with a variety of materials.
Students make simulated acid rain and test its reaction with a variety of materials as they:
- Relate the acidity of a solution to its pH factor
- Measure the change in pH of water as carbon dioxide is bubbled through it
- Demonstrate how acid rain can affect and damage materials
Students gain experience conducting the following procedures:
- Setting up the equipment and work area to produce carbon dioxide gas by reacting baking soda and vinegar, and trapping the gas in a balloon
- Bubbling the carbon dioxide gas through a straw into a beaker of distilled water to lower its pH, making a solution that simulates acid rain
- Testing the effect of the carbonic acid "rain" solution on various materials such chalk, an iron nail, limestone, and marble, and observing for signs of any chemical reactions
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
