Water Pollution in Plants
Researching how water pollution effects plant growth
THE PURPOSE OF THIS EXPERIMENT WAS TO SEE IF WATER POLLUTION HAD AN EFFECT ON PLANTS AND THEIR GROWTH.
HYPOTHESIS
If water used to water plants is polluted, then it will have a negative effect on the growth of the plant.
PARTS OF AN EXPERIMENT
Dependent: Growth of plants
Independent: pollution of the water
Control: plants watered with clean water
Experimental group: plants watered with motor oil water and soap water
Factors held constant: type of plant, amount of water, where the plants are kept, amount of time they grow for.
MATERIALS
300 pinto beans
6 plastic bags
6 paper towels
6 clear plastic boxes
1 journal to record data
Soil
Ruler
pencil
1 container of Motor oil
1 container of dish soap
PROCEDURES
Sort the pinto beans into six groups of fifty beans.
Get the paper towels damp (not dripping but wet),
Place 50 dried beans into the paper towel.
Place the damp paper towels with 50 beans inside into the plastic bags.
Seal the plastic bags.
Place in sunlight or warm area for 48 hours.
To prepare a place for the beans to grow, place 10-12 cm of dirt into the clear plastic bins.
Water the soil evenly so it is moist thought the top few cm
Place the beans in desired place of growth.
Place 3 cm of soil over the entire container and do this for all of the containers.
Keep the containers in the sun, and water consistently (as needed).
In 2 of the containers pour motor oil evenly over the top layer after plants are 3 cm tall
in 2 of the containers pour dish soap evenly over the top after plants are 3 cm tall
Record data every week
BACKGROUND INFORMATION
Testing the effects of motor oil and soap pollution in water is very important.It can determine if the chemicals in these can be harmful to the plants and animals in the water as well as the poeple that would drink it.
Triclosan is it antibacterial chemical found in soaps and toothpaste that can cause pollution and rivers lakes and streams. Increasing amounts are found in lakes across Minnesota. levels of this chemical found to be increasing since it's release in the 1970s. The chemical gets washed down the drain to serve some toothpaste and from then it goes into the storm drains and then into rivers lakes and streams. Treatment plants do not remove this chemical from water when it is being purified. It ends up getting into drinking water. Once it's in the water attaches to sediments and accumulates over time which potentially poses risks to aquatic life. when it accumulates in the water is and is exposed to sunlight the toxic byproducts are released and this is what is dangerous. As a result of drinking this chemical in the water there can be an altar and heart as well as increased breast cancer cells. The more that is taken in at this chemical the more issues it can possibly hold. Any other chemicals and personal care products that go down the sink can also cause many health issues and Are going into waters. Some chemicals Are eaten by the marine life, while others restrict some aquatic organisms abilities to remove the toxins in the water. Very little is actually known about these chemicals and how bad they can be this is just the beginning of noticing in the waters and it is getting researched more and more as it is becoming more evident in the waters. Nine of nine water samples taken from the Northwest had traces of chemicals from shampoos and sunscreen. All these chemicals pass right through treatment plants and into the waterways across the The country. Treatment plant do not remove this chemical because it would be very expensive and also because it is not a chemical found in the clean water act which hasn't been changed since 1977. this is a list of toxins that must be removed from water in order for it not to harm humans plants and animals. Not much is known about what these chemicals can you do the plants animals and humans from us is known about what all the chemicals mixed together that I found these products and then put in the water can do to organisms. Nonstick cookware also falls into this category because when they're washed that some of the chemicals goes down the drain is also causes pollution. Cars leak oil and gas is in the street and this goes into the storm drains which flows into rivers lakes and streams and pollutes the waters. Leaks often can go unnoticed for quite a long time causing tons of oils to go into drinking water. Water pollution is mainly caused by leaking cars fertilizers failing septic tanks and other engines. This kind of pollution can hurt drinking water fish plant the appearance of water and humans. Oil does not dissolve in water it sticks to everything from sand on the beaches to feathers on animals. This is toxic to people wildlife and plants. Just one court of oil can pollute 250,000 gallons of water. And 1 gallon of gas can pollute 750,000 gallons of water. Used motor oil is the number one leading cause of water pollution. This used motor oil can also come from boats in the waters. 180 gallons on average is spilled into the waters each year just buy American. This can easily be avoided with cleaning up oil leaks as well as making sure that you never have any and also using recycled oil. Used motor oil can contain toxic chemicals and heavy metals. It contaminates the water resources that give us her clean drinking water. Use your cycle has raw materials in the petroleum industry and lubricated oil.
DATA AND OBSERVATIONS
CONTROL
Growth occurred rapidly at a steady increase, death did not occur.
OIL
After the oil was placed on the plant, and in the soil no evidence of change occurred until day 3. At day three the leaves started to brown and shrivel up. Growth stopped at day three, death of the plant occurred at day five.

ANALYSIS
Water pollution is very bad for the growth and survival of plants that receive or live in said water. The most common kind of pollution found in water is motor oil, and soaps (which also has petroleum oil as one of its components. The experiments run tested these kind of pollution in water, and the effects they had on plants that got watered with the polluted water. Plants that were watered with the clean and pure water grew quickly and lively. They grew about 1.49 cm per day. The clean water allowed them to pursue all the functions they need to do in order to get food and and break down the food. The plants that received the polluted water died quickly and hardly grew. The pollution in the water made the water contaminated with things that a plant can not handle. This also makes it so the water cannot be used in photosynthesis, where it gets used in light reactions to make energy. Without the usable water, the plant does not have energy to make food, or breakdown food and it will not take long to die once this happens. The soap worse for the plants growing at 0.19 cm per day, however the motor oil took a big toll on the plants as well growing 0.22 cm per day. Both of these contain petroleum oil, which is the one of the main things and a huge issue that is polluting waters. The oil comes from many different sources, from dumping, which is where most motor oil and soap pollution comes from, run offs, oil spills, ship travel and drains. With this in the water the plants cannot survive easily if even at all.
