Acid Rain Go Away?

The effects of acid rain compared to normal rain on plants. Acid rain for this project is created based on different ph levels in the water.

Hypothesis

That acid rain (lower levels of ph) will kill the plants because acid rain is not normally part of the natural environment and is largely caused by pollution.  The plants watered with tap and rain water will stay alive.

Can Acid Rain Effect Humans?

Acid rain could affect humans if your breath in too much.  When acid rain particles from the rain get into people's lungs, they can cause health problems, or can make existing health problems worse. Acid rain   is not acidic enough to affect your skin. Acid Rain could lead to asthma or bronchitis.

What Places Are Common For Acid Rain

Northern United States, eastern Europe and parts of China and India are some of the most severe places for acid rain. The black triangle is an area that got severe acid rain during the 1970-80`s. It included parts of Czech Republic, Germany, and Poland. Places in Asia have been slowly increasing their amount of acid rain since the early 1980s. During 2023 the USA and eastern Europe has the worst records for acid rain due to thousands of coal burning facilities.

How do we reduce acid rain?

People can help stop acid rain by using les gas and fossil fuels and using more renewable energy.

Effects of Acid Rain on Plants and Trees

Not only can acid rain kill or stop the growth of acid rain also removes minerals and nutrients from the soil that trees and plants need to grow. At high elevations, acidic fog and clouds might strip nutrients from trees and plants insides or foliage, leaving them with brown or dead leaves and needles. Acid rain can flow into rivers and lakes and cause death for the plants and animals live underwater along with the creatures that drink from the lake or river. Acid rain mostly effects young trees and plants like seedlings or sprouts. If acid rain effects an older tree, it will most likely stop its growth or slow it down.

Fun Facts About Acid Rain

-Acid rain can travel long distances. (Facts.net)

-Acid rain can be neutralized just like acid. (Factsaboutnature.com)

-When acid rain soaks into soil it makes it impossible for plants to grow there. (Factsaboutnature.com)

-Acid rain can peel away paint and can do a lot of damage to buildings and other objects like cars. ( What is Acid Rain? | US EPA )

-Acid rain is created by sulfur dioxide (SO2) and nitrogen oxide (NOx). ( What is Acid Rain? | US EPA )

-Acid rain is a 4.2 on the ph scale. ( What is Acid Rain? | US EPA )

-Acid rain has elevated levels of hydrogen ions. (Factsaboutnature.com)

-95 000 lakes in north America have been damaged by acid rain. (Factsaboutnature.com)

-The smell and taste of acid rain is the same as normal rain. (Eartheclipce.com)

Variables

Independent variables:  the ph levels of the water (by adding different amounts of vinegar to the water)

Dependent variables: the health of the plants

Controlled variables: the type of plants, the amount of water given to each plant, the location of the plants, the time of day I water the plants

Procedure

Buy nine of the same plants (I bought charmaedorea elegans) and place in a spot with sunlight. 

First 3 plants will be watered with water that has the same level of ph as acid rain (4 ph).  Prepare the water by adding vinegar to the water and testing with PH strips until the PH strips read level 4.

Second 3 plants be watered with water that has the same level of ph as normal rain (5.6 ph).  The water would have a lower level of vinegar added but measured with the ph strips to make sure it was around 5.6 ph.

 

The last three plants will be watered with pure water (tap water at room temperature).

 

Will water each plant with a quarter of a cup two to four times a week.

 

I would water these plants during the time period for our experiments and observe the effects of the different ph level waters on the plants.

 

 I will make notes of how the plants look and take pictures each week and keep a log book.

Observations

Jan 10th - The plants look the same since I first watered them on Jan 9th.

Jan 11th- Still not that many changes. Acid rain smells a bit acidy, and the soil is a bit drier compared to Normal Rain and Tap Water. Normal Rains soil is damp, and Tap Water has a sprout in one pot. The sprout looks like a two-leaved clover.  Soil appeared dry, so I also watered the plants.

Jan 14th – Soil was dry, so I watered all the plants.

Jan 17th - Soil was dry, so I watered all the plants.

Jan 20th- Lots of changes are starting to happen. Tap water is growing well, it’s lush and tall. Normal rain hasn’t seen much change, it isn’t as lush as tap water but looks way better than acid rain. Acid Rain is drooping, smaller and has paler leaves than the rest. It is less lush and green then the others.  I also watered the plants today.

Jan 22nd-(The Acid Rain starts to really effect the plants after 12 days).  The soil of the acid rain plants has mold that is green and white and fuzzy.  Normal rain has one stem with a leaf that grows higher than others and sticks up from the plant, otherwise not much change.  The tap water plants are growing well, both tall and wide.  Also is a vibrant green.   

Jan 27th – Soil was dry, so I watered the plants.

Jan 28th – The stems and leaves of the acid rain plants are crinkly and dry to the touch.  They are also starting to brown.  Its soil is damp.  Normal rain plants are tall, but not that lush.  Tap water plants are doing the best, they are tall with moist vibrant green leaves and very lush.  

Jan 31st-Here is the final hights of each plant:

Analysis

Based on my experiment, PH levels of 4 (acid rain) have a significant impact on plants.  That impact can be seen as early as 12 days after the first exposure to Acid Rain. Ph levels of 5.6 (Normal rain) has a mild impact it looks haelthy and tall by itself, but putting it beside tap water it dosent look as good.  Ph levels of 7 (tap water) acts amazing as the plants are super lush, tall and healhy. 

Conclusion

Acid Rain has a negative effect on plants on plants as seen in this experiment.  After 12 days acid rain began to have an impact and after 3 weeks the plants watered wtih acid rain were dying.  The plants with nutral ph (no acid rain effect) were lush and green.

 

Application

Supports why the reduction pulution is important. If we continue to see a lot of polution there for creating acid rain we will see our plants dying that will impact the fresh air we need to breath

Sources Of Error

If I used a different plants, the resuls could have been different.

The temperature of the house where the experiment took place, could have effected the plants.

The ph strips could have been off on their ph measurements.

The amount of sunlight the plants received could have effeted the growth of the plants..

All plants were watered at different times during the day (morning, afternoon or evening), this could have effected the plants.
