Acid rain is rain that is more acidic than usual, it possesses elevated levels of hydrogen ions which is a low pH level. Acid rain can have harmful effects on plants and aquatic animals. "Acid rain is caused by emissions of [|__carbon dioxide__], [|__sulfur dioxide__] and [|__nitrogen oxides__] which react with the [|__water__] molecules in the atmosphere to produce acids." (======

Acid rain is not normal and very harmful. The Independent variable in this project is the amount of acid added to the plant. It will be manipulated by the amount of acid rain to the plant. The Dependent Variable in this project will be how much the plant is affected by the acid rain. It will depend on the amount of liquid poured onto the plant. The possible relationship between the independent variable and the dependent variable is that they will both be depending on each other. The constants are the things that will be kept the same throughout the experiment. The things that won’t change are the soil being used, the container that the plant will be in, the amount of sunlight that each plant will receive, and the seed that will be used. They should stay unchanged because then the whole experiment can change. With the different amounts of acid rain that are added, the effects will be different. All of the effects with the different amounts of water will be different.======

Even in areas with out the factories and vehicles have acid precipitation because the wind blows the pollution to other parts of the world. The main causes of acid precipitation are cars and their exhaust and the other is factories and the burning of fossil fuels.

=
Other than plants and animals that are affected by acid rain, buildings and stone statues are also affected by this rain. The effects of acid precipitation are getting worse as more cars and factories are made. Acid precipitation is damaging thousands of lakes, ponds, rivers, and streams worldwide. There aren’t many forms of prevention, which is not really helping the problem ======
