To make acid rain for a science project, use vinegar or vinegar dissolved in water. Change the concentration of vinegar in the solution to imitate more or less acidic rain.
Acid rain is the result of pollution in the atmosphere. Nitrogen dioxide and sulfur dioxide change in the atmosphere and enter the clouds. Within water droplets, the pollutants combine with the hydrogen and oxygen, thus creating acid. After it rains or snows, the soil absorbs the acid, and the chemical balance of lakes and streams is also changed. Acid rains cause considerable harm to the environment. Living organisms as well as buildings are adversely affected.
- Collect materials to see what effect acid rain has on them
- Observe the rate of deterioration of the materials
- Record the results
Take 3.5 ounces each of granite, brick, limestone and marble. Prepare weighing scale, four containers, 7 cups of vinegar and a piece of cloth. Divide the vinegar equally between the four containers.
Leave the construction materials in vinegar for a day. Take out the blocks, clean with the piece of cloth and weigh each block. Record the results. Repeat three more times.
After the 4th day, see which material lost most weight and thus turned out to be most susceptible to the destructive effects of the simulated acid rain. Make a note of the results.
