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

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 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
