Name: Corrina Marcus Date: 7/27/13
Student Exploration: Water Pollution
Vocabulary: bacterial pollution, nutrient pollution, sediment pollution, toxic pollution, water pollution
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Water pollution is the addition of harmful substances to water. Some of these substances are found at home. What household chemicals might be harmful if not disposed of properly?
Clorox, batteries, and cleaning supplies
2. What are some other causes of water pollution?
Oil spills and gases in the water
Gizmo Warm-up
The Water Pollution Gizmo™ will teach you about some of the main kinds of water pollution. On the TYPE tab, under Types of pollution, check that Toxic is selected. Read the paragraphs on the right and bottom of the Gizmo.
1. What is toxic pollution?
Are generally considered to be materials that cause death, disease, or birth defects in organisms that ingest or absorb them. The quantities and exposures necessary to cause these effects can vary widely.
2. What are some examples of toxic pollutants listed in the Gizmo? death, disease, or birth defects.
3. Can you think of other examples of toxic substances, not listed in the Gizmo? no

Question: What are the main types of water pollution?
1. Read and learn: Besides toxic pollution, the other types of pollution are sediment pollution, nutrient pollution, and bacterial pollution. You have already described toxic pollution on the previous page. Read about the other types, and describe each in your own words.
Sediment pollution
Description: is the pollution brought about by rivers carrying dust and other fine or coarse particles. Causes: deforestation, poor farming practices, industrial dumping of waste that is unregulated. Consequences: poor light quality is the first consequence of high sediment concentration in the water.
Nutrient pollution
Description: is a from of water
