Water Pollution IntroductionIf we pollute our waters with trash we risk not

having clean waterHumans can catch diseases from polluted

waters Approximately 80% of water pollution comes

from land based activitiesAbout 20% of people do not have safe water to

drinkChemicals from smoke at power plants can go

into the air and eventually go into the watersApproximately 25% of the beaches are closed

each year due to sewage from water pollution

TrashWater polluted by trash can hurt our

environmentPlastic left from fishing nets or lines can tangle

the marine life and kill itCans or bottles can be mistaken for food by

marine lifeWaste from household repairs can pollute

our watersUse pesticides and fertilizers sparinglyClean paint brushes in a sink, not outdoors

bottled water or filters to make sure they have clean water to drink

Water Pollution ExperimentIn my experiment I will water plants with

soapy and clean water to show how chemicals in the soap can harm the environment

My experiment has these parts:HypothesisSetupDataResultsConclusion

HypothesisSoap is a chemical that we use every

dayUsed to wash our hands or clothes

Using the right amount of soap for every day things helps the environment

Plants that are watered with clean water live a healthier life than plants watered with soapy water

Experiment SetupMaterialsControl steps – used for a control plant,

because they can tell me how that plant reacts to clean water

The experiment took me 7 days because I needed to see how much the plants changed over some time

I recorded information about how the plants reacted to their water

Data - TablePlant #1 Plant #2 Plant #3

Day 1 1 1 1

Day 2 1 1 1

Day 3 1 2 2

Day 4 1 3 3

Day 5 1 3 3

Day 6 1 3 6

Day 7 1 4 8

There are no changes in any of the plants on Day 1 and 2

Some changes were noticed on Day 3 and Day 4

On day 5 the leaves on the plants that are watered with soapy water stayed the same as Day 4

On Days 6 and 7 the plants that were watered with soapy water began to wilt and the leaves were dry and yellow

The pictures on the next page were used to identify how the plants changed.

The data in Table 1 shows how the plants changed each day, based on the pictures.

The graph helps show information in the table.

A number 1 in the table and graph means the least change and a number 10 in the table and graph means the most change.

Plant #1 is the control plant.

Plants on day 1All 3 plants are healthy with green leaves and yellow flowers

May 20, 201112

Plants on Day 7Plant 1 healthy leaves, Plant 2 leaves are not as healthy, Plant 3 leaves are dry and yellow

May 20, 201113

ConclusionThe control plant had the least amount

of changePlant #3 changes the mostPlant #2 changes, but not as much as

plant #3My hypothesis was correct because I

thought that plant #3 was not going to be as healthy as the others because of the soap
