Water pollution and its effects on

A polluted environment is a polluted society - one we created and one only we can renew. Pollution is defined as the introduction of harmful substances or products into the environment, which are typically foreign substances, particularly a contaminant or toxin, that produce some kind of a negative or harmful impact on the environment or living beings. Pollution occurs in many forms ranging from chemicals in the form of gases or liquids, noise, energy sources such as light or heat, or solids such as the types of waste that end up in landfills. Even naturally occurring substances, such as carbon dioxide and mercurycan be considered pollution when additional quantities are added to the environment in unsafe amounts by industries which can have detrimental effects on the environment and all forms of life, including humans.

Mary Matyskiela, Lani Keller Summary: Students brainstorm different sources of pollution. Then, students make their own miniature ocean inside a water bottle, and pollute it with waste and oil to observe the effects on animals in the water.

A demonstration shows students the effect of oil on birds' feathers and discuss the consequences of oil spills for water birds. Students will be able to see first hand how animals in the ocean Water pollution and its effects on affected by the pollution we create.

They will see how pollutants spread into the whole ocean, and how birds are coated by oil that doesn't wash off in an oil spill. This will result in a better understanding of why pollution is bad and why they should take steps to reduce it.

Add a few drops of blue food coloring to tap water to make the "ocean water" and fill bottles half way with dyed water.

Make a pollution mix and keep it in a separate bottle. We mixed red food coloring, sprinkles, mayonnaise, green food coloring, soy sauce etc. The grosser, the better, but don't make it so dark that you won't be able to see into the water bottle afterwards.

Point out how much of this pollution ends up in our oceans--You can specifically point out the drains on the street that drain directly to the ocean! Pass out the water bottles filled with blue water and tell the students that this is their model ocean.

Pass out the sinking and floating beads at least one of each to the students and have them decide what animal each will represent--the class can brainstorm about bottom dwellers starfish, crabs, lobsters, etc.

Using a funnel, pour into each student's bottle some of the pollution mixture. Have them write down where the pollution went and which animals it affected--it spreads everywhere and affects all the animals!

Now talk a little bit about how we need oil in order to drive our cars and power our machines, and we have to ship this oil across the ocean, and if this oil spills, it is a really really bad kind of pollution.

Using a funnel, pour into each student's bottle some oil.

Ask them to notice where the oil is--it is on the TOP, affecting the animals on the surface. You can use this to talk about how oil and water do not mix, and oil is less dense that water so it goes to the top, if you have time or the students have learned about density.

Finally, tell them a storm is coming and let them finally shake their bottle up and down. Have them all stop shaking their bottle at the same time and put them down on the desk together.

So the surface animals aren't the only ones affected in an oil spill. To further demonstrate the negative effects of oil as a pollutant, you can do the following demonstration: Have everyone get on the floor in a big horseshoe.

Sit in the middle of the circle and make sure everyone can see. Hold a feather up in the air and talk about a bird that is flying in the sky over the ocean, looking for something to eat.

Then when it sees something to eat, swoop the feather down and dip it in a clear cup of water to show the bird diving down into the ocean.

Pull the feather back out of the water. It will be wet, but the water will bead up and drip off, and if you give the feather a quick shake, it will be almost as good as new. Pass it around for the students to see. Now take a cup of oil and talk about the same bird looking for something to eat.

Use a different but identical feather so that you can compare it to the previous feather afterwards. Dip the feather into the oil this time.Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of certain nutrients in water can cause a number of adverse health and ecological srmvision.comen, in the forms of nitrate, nitrite, or ammonium, is a nutrient needed for plant growth.

About 78% of the air that we breathe is composed of nitrogen gas, and in some areas. Factory Farm Pollution In today’s world there are a host of serious environmental problems, and factory farming is one of the top causes of pollution.

[1] Scientific research has found that factory farming’s method of crowding and confining animals in warehouse-like conditions before killing them and mass-producing both “meat” from cows, pigs and chickens as well as dairy and eggs.

Types and Sources of Water Pollution There are several major types of water pollution. One of the most destructive types is Petroleum srmvision.comeum products, such as oil and gasoline, enter.

What are the causes of water pollution? Most water pollution doesn't begin in the water itself. Take the oceans: around 80 percent of ocean pollution enters our seas from the land. Virtually any human activity can have an effect on the quality of . Water pollution occurs when a body of water becomes contaminated.

The contamination could be caused by physical debris such as plastic water bottles or rubber tires, or it could be chemical such as the runoff that finds its way into waterways from factories, cars, sewage treatment facilities, and air pollution.

Environmental pollution is one of the greatest problems that the world is facing today causing grave and irreparable damage to the earth, damaged atmosphere and depleted ozone layer leading to global warming. Environmental pollution consists of five basic types of pollution, namely, air, water.
