Water Pollution Introduction
 If we pollute our waters with trash we risk not having
clean water
 Humans can catch diseases from polluted waters
 Approximately 80% of water pollution comes from land
based activities
 About 20% of people do not have safe water to drink
 Chemicals from smoke at power plants can go into the
air and eventually go into the waters
 Approximately 25% of the beaches are closed each year
due to sewage from water pollution

Trash
 Water polluted by trash can hurt our environment
 Plastic left from fishing nets or lines can tangle the marine life
and kill it
 Cans or bottles can be mistaken for food by marine life
 Waste from household repairs can pollute our waters
 Use pesticides and fertilizers sparingly
 Clean paint brushes in a sink, not outdoors

Safety
 Many people spend extra money on bottled water or
filters to make sure they have clean water to drink
 Water pollution laws need to be followed to make sure
water is safe to drink and swim in

Water Pollution Experiment
 In 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:
 Hypothesis
 Setup
 Data
 Results
 Conclusion

Hypothesis
 Soap is a chemical that we use every day
 Used 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 Setup
 Materials
 Control 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

 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

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

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

Conclusion
 The control plant had the least amount of change
 Plant #3 changes the most
 Plant #2 changes, but not as much as plant #3
 My hypothesis was correct because I thought that plant
#3 was not going to be as healthy as the others because
of the soap
