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 May 20,

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 May 20,

Chemicals The following chemicals can cause pollution Soap from washing your car Oil and antifreeze from leaking cars Fertilizers Sediment from when trees are cut down Waste from household cleaning supplies Solvents like nail polish remover and paint thinner Chemicals from industrial plants Smoke Paint May 20,

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 May 20,

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 May 20,

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 May 20,

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 May 20,

Data - Table Plant #1Plant #2Plant #3 Day 1111 Day 2111 Day 3122 Day 4133 Day 5133 Day 6136 Day 7148 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 May 20,

Data - Chart 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. May 20,

Plants on day 1 All 3 plants are healthy with green leaves and yellow flowers May 20,

Plants on Day 7 Plant 1 healthy leaves, Plant 2 leaves are not as healthy, Plant 3 leaves are dry and yellow May 20,

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 May 20,
