What Effect Does Acid Rain Have On Plants
Acid rain is a complex environmental problem that concerns many environmental and chemical engineers. When engineers assess the damage of acid rain to water, wildlife, forests, plants and buildings, they consider the impact on human health. Engineers are designing many useful technologies that help industry reduce the amount of harmful pollutants emitted into our air. Engineers also help develop laws that prohibit or limit factories and industries from burning fossil fuels (which emit pollutants), or require them to reduce their emissions.

Academic Standards Each course or activity is associated with K-12 science, technology, engineering or mathematics (STEM) academic standards. All 100,000+ K-12 STEM standards covered are collected, stored and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org). In ASN, the standards are arranged in order: first by source; eg, regionally; within the source by type; eg, science or mathematics; within type by subtype, then by grade, etc. NGSS: Next Generation Science Standards – Science
MS-ESS3-4. Develop an evidence-based argument for how population growth and individual use of natural resources affect Earth’s systems. (Grades 6 – 8)
Conduct investigations to generate data that will serve as a basis for evidence that meets the objectives of the investigation.
Generally as the population and individual use of natural resources increase, so does the negative impact on Earth unless the activities and technologies involved are designed otherwise.
The Effects Of Acid Rain
All human activities draw on natural resources and have short and long-term effects, positive and negative, on human health and the environment.
Scientific knowledge can explain the consequences of actions but it does not necessarily explain the decisions made by society.
Acid rain is an environmental problem that worries many environmental and chemical engineers. Engineers always consider the potential effects of acid rain on human health and the environment when assessing damage to water, wildlife, forests and plants, and contamination of drinking water.
Acid rain is defined as any form of wet precipitation (rain, snow, fog, dew or sleet) with a pH below 5.6 (on a scale of 0 to 14, with 7 being neutral). Large amounts can also be placed in a dry dusty environment. Acid rain is more acidic than normal rain and forms through a complex process of chemical reactions involving air pollution and water molecules in the air. The two most important pollutants that contribute to the formation of acid rain are nitrogen and sulfur compounds, which react with atmospheric moisture to form nitric and sulfuric acids.
Is Acid Rain Harmful To Animals?
Sulfur and nitrogen compounds that contribute to acid rain mainly come from combustion products (burning coal and oil) from large industrial and utility sites. Carbon emissions also come from cars and other forms of transportation, and some industrial processes.
The effects of acid rain may not be immediately apparent. For example, at first glance, a lake may look clear and beautiful, but a closer look may reveal few living things. Some species of fish cannot survive in water with a pH below 5. Clams, snails, crayfish and other crustaceans, brook trout, walleyed pike and bullfrogs are very sensitive to acidity in water. Therefore, the pH does not have to drop too low before the fish cannot survive. Insects, birds and mammals are also greatly affected by acid rain. Acid rain can change soil chemistry, nutrient availability and plant growth. In their weakened state, trees and shrubs are vulnerable to insects, diseases and fungi. For more information, see the Acid Deposition Study and the estimated pH of the Common Substances Reference Sheet.
One way we can help prevent acid rain is by burning less fossil fuel. Other types of industries that burn a lot of coal and oil include large power plants, and paper and wood processing plants. Engineers have helped create laws that prohibit or limit large factories and industries from burning fossil fuels or require them to reduce their emissions. Engineers have also developed many useful technologies to help industry reduce harmful air pollution, but companies must comply with regulations and use these technologies.
: Using the Effects of Acid Rain Worksheet, ask students to record some predictions. If the vinegar contains an acid (acetic acid), how will the substances placed in the vinegar change? If these things are put in water, will they change in the same way that vinegar does?
Here Are Some Of The Most Important Effects Of Acid Rain On Humans
: Using the Effects of Acid Rain Worksheet, ask students to write down what they saw happen to things after one day and one week.
: Ask students to complete the questions on their Acid Rain Effects worksheets. You may wish to discuss some of these as a class.
: Ask students to write a detailed description of how acid rain will affect their world. For example, a tree in the playground, a pencil they use, a local plant or a local park, etc.
Allow at least 24- 48 hours for the effects of the vinegar to appear on the leaf and eggshell.
Acid Rain Facts And Information
Look for pictures online or in books/magazines that show evidence of acid rain damage. Discuss the general and specific types of damage to living and non-living things.
If you know of physical evidence of acid rain in your community, plan a trip to see it and check it out.
Be aware of the effects of acid rain on living plants. Water the control plant with distilled water and the other with vinegar water (1 tablespoon vinegar per 1 cup distilled water). You can also water them both with distilled water and sprinkle them with distilled water or vinegar water to simulate rain more accurately. Discuss/examine materials that can be added to soil to combat the effects of acid rain.
Make a third solution (perhaps with lemon juice or a vinegar/water mixture) and compare/list the results or make a bar graph.

Students are introduced to acids and bases, and the environmental problem of acid rain. Students also do a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment.
Students are introduced to the difference between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They learn why it is important for engineers to understand acids and bases.
Students are introduced to the main types of erosion—chemical, water, wind, ice, and temperature. Students investigate examples of each type of erosion and discuss how erosion changes the surface of the earth.
What Is Acid Rain?
Students are introduced to the concepts of air pollution, air quality, and climate change. Three parts of the course (including related activities) focus on the requirements for understanding air pollution. First, students use M&M® candies to create pie graphs that show their understanding…

Acid rain, also called acid rain or acidification, is rain with a pH of 5.2 or less that is primarily produced from the release of sulfur dioxide (SO
) from human activities, especially the burning of fossil fuels. In acid-sensitive areas, acidification can reduce the pH of surface water and decrease biodiversity. It weakens trees and increases their susceptibility to damage from other stressors, such as drought, extreme cold and pests. In acid-sensitive areas, acid rain also depletes the soil of important plant nutrients and buffers, such as calcium and magnesium, and can release aluminum, which is bound to soil particles and rocks, in its toxic dissolved state. Acid rain contributes to the deterioration of areas exposed to air pollution and is responsible for the deterioration of limestone and marble structures and monuments.
How To Prevent Acid Rain Pollution
It was first used in 1852 by Scottish chemist Robert Angus Smith when he was investigating the chemistry of rainwater near industrial cities in England and Scotland. This situation became an important part of his book
(1872). However, it was not until the late 1960s and early 1970s, that acid rain was recognized as a regional environmental issue affecting large areas of western Europe and eastern North America. Acid rain also occurs in Asia and parts of Africa,
