Try these first

1. 1.

   What are nanoparticles?

   Hint

   Think about the scale of these particles compared to everyday objects.

2. 2.

   What is remediation?

   Hint

   Consider how we fix polluted water or soil.

3. 3.

   What is the primary function of nanoparticles in remediation?

   • Sequestration of toxic waste
   • Enhancing production time
   • Improving visibility of pollutants

   Hint

   Think of what remediation aims to achieve.

4. 4.

   True or False: Mitigation strategies can include the use of nanotechnology.

   • True
   • False

   Hint

   Reflect on how technology impacts environmental strategies.

5. 5.

   Assess how the efficiency of solar cells made with silicon nanowires can compare to traditional energy sources in terms of cost and environmental impact.

   Hint

   Compare the operational costs and emissions from traditional versus nanotech-based energy solutions.

6. 6.

   Debate the ethical implications of using nanotechnology in environmental remediation in developing countries.

   Hint

   Reflect on both sides of technological implementation, particularly in sensitive regions.
