Water Remediation Lesson Plan Example for 12th Grade Students

Topic: water remediation

Objectives & Outcomes

• To understand the different types of water remediation and their applications.

Materials

• Sample of polluted water
• Various types of water remediation equipment (e.g. air bubbler, air stone, biofilter, reverse osmosis machine)
• Handouts with information on the different types of water remediation

Warm-up

• Ask students if they have ever come across a situation where they had to deal with polluted water. Ask them to share their experience and what they did to resolve the issue.
• Introduce the topic of water remediation and explain that it is the process of cleaning up polluted water.

Direct Instruction

• Explain that there are different types of remediation that can be used to clean up polluted water, such as physical, chemical and biological methods.
• Provide examples of each type of remediation and explain how they work. For physical methods, explain how processes such as filtration and sedimentation can be used to remove impurities from water. For chemical methods, explain how processes such as oxidation, precipitation and neutralization can be used to remove certain types of impurities. For biological methods, explain how processes such as bio-remediation and bio-degradation can be used to degrade and remove certain types of pollutants.
• Provide examples of how each type of remediation can be applied in real-world situations. For physical methods, explain how large-scale processes such as water filtration and purification can be used to clean up polluted water. For chemical methods, explain how processes such as oxidation can be used to clean up contaminated soil and groundwater. For biological methods, explain how processes such as bio-remediation can be used to clean up waste water and landfill sites.

Guided Practice

• Give students a handout with examples of different types of pollutants and their respective remediation methods.
• Have students work in small groups to discuss and identify the appropriate remediation methods for each example. Encourage them to consider the characteristics of each type of pollutant (e.g. its chemical makeup, its molecular size) and the characteristics of each type of remediation (e.g. the types of impurities it can remove, the methods of action) when making their choices.
• After a few minutes, bring the class back together and have students share their answers with the class.

Independent Practice

• Have students work on a project-based independent practice where they must identify and research a real-world application of water remediation.
• Students can choose to focus on a specific type of remediation (e.g. adsorption) or on a specific application (e.g. drinking water filtration).
• Encourage students to use the scientific methods and concepts they have learned to critically evaluate the efficacy and limitations of the chosen application.

Closure

• Review the key concepts and skills learned in the unit.
• Ask students to reflect on what they enjoyed about the unit and what they found most challenging.
• Ask students to share any insights or personal reflections they have on the topic of water remediation.

Assessment

• Formative -Observation of class participation, completion of worksheet and demonstration of understanding of key concepts and skills during independent practice.
• Summative -Written test on understanding of key concepts and skills, including application of concepts to a variety of water remediation scenarios.
