Students will simulate acid rain effects by applying solutions of varying pH levels to samples of common building materials. The project focuses on understanding how acid rain can damage infrastructure.
If the pH of the solution is lower, then the building material will show more signs of damage due to increased acidity.

Prepare acidic solutions with different pH levels by diluting hydrochloric acid with distilled water.
Use pH strips or a meter to confirm the pH of each solution.
Label each building material specimen.
Immerse each specimen in the corresponding acid solution.
Observe and note any visible changes over time.
Remove the specimens after a set time and examine for damage.
Record the degree of damage for each material and solution.
Compare the effects on different materials.
More acidic solutions will likely cause more noticeable damage to the materials, with softer materials like limestone and marble showing more deterioration.

Handle acids carefully, wear gloves and goggles to prevent skin and eye contact.
Use before and after photos to illustrate material changes.
Explain how acid rain forms and its environmental impact.
Discuss potential solutions to mitigate acid rain damage.
pH measures acidity, indicating potential material damage from acid rain.
Yes, testing other materials like metal or concrete could be insightful.
Burning fossil fuels releases sulfur and nitrogen compounds that form acids in the atmosphere.
