​

With the development of nanotechnology, some of the scarce materials around the world may be substituted with nanomaterials such as graphene. This could also have a cascading effect on the globe in terms of solving some global issues while potentially raising new ones. 

​

For this activity, you will need to research and develop some arguments for and against the substitution of critical materials for nanomaterials. 

​

Instructions:

• Split into 6 groups covering topics forthe substitution of nanomaterials in place of critical materials and the others will be againstthe substitution, raising some issues about the substitutions.

• You can choose how you present your topic: role play, news report, Power Point presentation or through multimedia such as a Digi explanation (www.digiexplanations.com)

• These presentations will inform other students on their selected topics and showcase a different perspective on each issue from various angles.

 

Topics for the substitution:

​

1. The benefits of not relying on critical materials by using Nano substitutes such as graphene and potentially resulting in cheaper access to technologies through these substitutes.

2. Dissolving rebel groups where critical materials are found for example the Democratic Republic of Congo.

3. Potential technological advancement through the funding and development of these substitutes. For example, the development of newer fabrics and other accidental discoveries. Also, what should the government do in order to assist this process?

 

Topics against the substitution:

​

1. Potential build-up of nano toxins in the environment that may have devastating effects.

2. Production safety with the development of nanomaterials. The accumulation of inorganic toxins that may be detrimental to the workers’ health. Is there enough scientific evidence to prove its safety?

3. How can the government regulate the development of new nanomaterials? What laws and policy should be in place to protect society?
