- Natural and human-induced hazards
- Science and technology in local, national, and global challenges
Students will be able to:
- Determine where the origin of their drinking water
- Determine the effects on human beings if contaminants such as, E. coli were found in drinking water
- Identify the parameters of water quality
- Describe how abnormal amounts of each parameter affects the organisms found in a particular body of water
Context (Background information for teachers):
Many students have no idea where their water comes from, or how human actives can affect the quality of the water source that they rely on for drinking and everyday use. The teachers should have an understanding of where the city water comes from, as well as many of the local pollution and water quality issues. You should be able to explain to the students where their water comes from, describe the watershed, and many of the human actives that take place in that area.
- Laptop Computers and possibly local maps
- Assignment description handouts
- Water Quality Packets (There should be 1 sheet for each water quality parameter assisgned)
Students will be paired and assigned a water quality parameter to investigate and present to their classmates.
Day 1 - Students will be asked probing questions to determine their prior knowledge about:
- the characteristics of water
- the parameters that determine water quality
- the origins of their drinking water
- possible water pollutants, and
- the impact of pollutants in water on aquatic organisms and human beings.
- Lecture will contain information on the above mentioned topics.
Days 2-6 - Lecture will continue today if time is needed.
Students will be divided into pairs. Each pair will be assigned a water quality parameter to research. They will be given four days to do their research and to prepare a power point presentation.
Days 7 & 8 - Students will present their research via power points. Each student will be given a packet of blank water quality parameter and contaminant pages to fill in as they listen to their classmates’ presentations. This packet can later be used as a water quality reference.
PowerPoint presentations on an assigned water quality parameter and the completion of their packet.
Do water quality sampling to see what is in the local watersheds.
