M2 L3 Gizmo Simulation: Water Pollution - Honors 2020

M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 BIO 197 M2_L3_Gizmo_Simulation_Water Pollution_-_HONORS 2020 – University Of Nevada Name: Thao Ho Date: 6/11 Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 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? Household chemicals that may be harmful are bleach, disinfectant, and air freshener. What are some other causes of water pollution? Other causes of water pollution are industrial chemicals and mining wastes. Gizmo Warm-up M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 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. What is toxic pollution? Toxic pollution is chemicals that are extremely harmful for all types of life and can cause impairment by disease, death and birth defects. What are some examples of toxic pollutants listed in the Gizmo? The examples that are listed are radioactive waste, pesticides, mercury, lead, gasoline, oil, paint and battery acid. Can you think of other examples of toxic substances, not listed in the Gizmo? One that comes to mind is fossil fuels when oceans store it. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 Activity A: Types of water pollution Get the Gizmo ready: · Check that the TYPE tab and Toxic pollution are selected. 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 above. Read about the other types, and describe each in your own words. Type of Pollution Description Causes Sediment pollution When the natural process of erosion occurs we see sediment (rocks, soil, etc) get carried away by wind and water, it starts to build up in unwanted places such as rivers and it blocks up and pollutes the water. The cause is something we can not control which is erosion. Erosion happens naturally as time goes by. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 Nutrient pollution Nutrient pollution is when the water is overrun with nutrients which makes the overgrowth of algae. The more algae grow, the more they decompose which takes up available oxygen from other water organisms. Nitrogen and phosphorus derive from human waste, detergent and fertilizer. Bacterial pollution Bacteria comes from fecal waste from both humans and animals. If consumed it could cause disease. It also creates a big problem for the organisms within the water which can affect their health Untreated human waste plays a big factor in the this pollutant and it creates unnecessary problems. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 Activity B: Real-world examples Get the Gizmo ready: · Select the EXAMPLE tab. · Check that example 1/12 is selected. (If not, use the arrow buttons to get to example 1/12.) Question: What are the real-world causes of water pollution? Practice: For each Real-world example presented in the Gizmo, guess which type or types of pollution will result by checking the boxes. When you are ready, click Check answer to see if you were right. Read the explanation, and then use your own words to fill in the table. Example Pollution Type(s) Explanation 1 Nutrient and Bacterial Manure is a fertilizer made out of animal fecal which has nutrients within it which creates nutrient and bacteria pollution. 2 Toxic and nutrient Gasoline has both toxic chemicals and overpowered nutrients which creates toxic and nutrient pollution. 3 Toxic and nutrient Fertilizer, herbicides, and pesticides contain toxic chemicals and nutrients that M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 cause toxic environment for organisms and an overload of nutrients. 4 Sediment Sediment will cause significant blockages for the aquatic wildlife and health defects. 5 Toxic Oil and antifreeze could cause major toxicity and health defects in the water. 6 Sediment Without vegetation, erosion can cause sediment pollution. 7 Toxic Paint and solvents are toxic to the environment and can lead to defects for the organisms in the water. 8 Nutrient and bacterial Human fecal matter in sewage can cause both nutrient and bacterial pollution. 9 Sediment Paper and cardboard causes a decrease in trees, and can expose more area to erosion. 10 Toxic and sediment Oil and antifreeze cause health defects to wildlife in the stream. Removing land can cause sediment pollution. 11 Nutrient Too much fertilizer can cause nutrient overrun. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 12 Nutrient and bacterial Human fecal matter can have lots of bacteria and bad nutrients for the environment. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 Practice: Classify each of the following examples as toxic, sediment, nutrient, and/or bacterial pollution. Explain your classifications. Logging removes trees from a hill, leaving a barren landscape. Classification: Sediment Explanation: Trees are something that can prevent erosion due to their complex root systems which keeps the soil in place. Now there are no trees, sediment can easily disperse in the water. A man washes clothes in a stream using a detergent that contains phosphorus. Classification: Nutrient Explanation: Phosphorus is a nutrient that could cause the growth of vegetation or algae to increase leading to lack of oxygen for other organisms within the ecosystem. At an old gas station, gasoline leaks from an underground storage tank. Classification: Toxic Explanation: Gasoline is not a good thing for aquatic life and can lead to defects and death when in water. M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 At a research lab, a scientist carelessly pours cultures of living microbes down the drain. Classification: Bacterial Explanation: Drinking or living in water that is contaminated with bacteria can be deadly as it can cause disease. Think and discuss: Many sources of water pollution are found within the home. What actions can you take to reduce water pollution? I could think about more consciously about what i put down the drain and advise others to.M2 L3 Gizmo Simulation: Water Pollution - Honors Revised by NVLA: 06/10/2017 BIO 197 M2_L3_Gizmo_Simulation_Water Pollution_-_HONORS 2020 – University Of Nevada Name: Thao Ho Date: 6/11 Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
