Humans use the Earth's resources to provide warmth, shelter, food and transport. |
|
What do humans use the Earth's resources for? Think Pair Share
Show picture of a carton of orange juice. Get students to think about all of the different materials that go into making that product and where they come from. |
|
|
|
Natural resources, supplemented by agriculture, provide food, timber, clothing and fuels. |
|
What do natural resources provide? |
|
|
|
Finite resources from the Earth, oceans and atmosphere are processed to provide energy and materials. |
|
What are finite resources used for? |
|
|
|
Chemistry plays an important role in improving agricultural and industrial processes to provide new products and in sustainable development, which is development that meets the needs of current generations without compromising the ability of future generations to meet their own needs. |
|
What role has Chemistry played in improving agricultural and industrial processes? Analyse data as to estimates of how long different resources will last.
What options do we have and when they run out |
|
|
|
Students should be able to state examples of natural products that are supplemented or replaced by agricultural and synthetic products. |
|
What are the names of natural products that are supplemented or replaced by agricultural and synthetic products? Research examples of natural products that are supplemented or replaced by agricultural and synthetic products. (NYLON) |

|
Students should be able to distinguish between finite and renewable resources given appropriate information. |
|
What is the difference between finite and renewable resources? |
|
|
|
Students should be able to extract and interpret information about resources from charts, graphs and tables. |
|
|
|
|
|
Students should be able to use orders of magnitude to evaluate the significance of data. |
|
What are orders of magnitude? |

Life cycle assessments (LCAs) are carried out to assess the environmental impact of products in each of these stages:
- extracting and processing raw materials
- manufacturing and packaging
- use and operation during its lifetime
- disposal at the end of its useful life, including transport and distribution at each stage. |
|
What different aspects of a products lifetime are assessed through a life cycle assessment? TED talk LCA's:

|
|
Use of water, resources, energy sources and production of some wastes can be fairly easily quantified. Allocating numerical values to pollutant effects is less straightforward and requires value judgements, so LCA is not a purely objective process. |
|
Why are life cycle assessment not a purely objective process? Carry out a simple comparative LCAs for shopping bags made from plastic and paper. Info on shared drive |
|
|
|
Selective or abbreviated LCAs can be devised to evaluate a product but these can be misused to reach pre-determined conclusions, eg in support of claims for advertising purposes. |
|
Why is it important that life cycle assessments are completed by an unbiased impartial agency? |
