Identify typical roles of the element(s) and compounds in the biosphere.

Some elements involved in geochemical and bio geochemical cycling are of concern in relation to

limited natural or ready availability (via industrial production) of the compounds involved in the

cycles. Select one or more of these elements, engage in some research and prepare a short essay,

with appropriate references, that describes the present and possible future situation in relation to

the security of the cycle. Structure your work with an introduction, your findings and conclusions

(using font size 12 and 1.5 line spacing). You should start your research from your present

individual knowledge of chemistry (allowance will be made for this in the assessment). Word Count: 800 (excluding references)

i. Identify typical sources and sinks of the element(s)

ii. Estimate typical lifetimes as [flow of material /amount available]

iii. Identify typical roles of the element(s) and compounds in the

biosphere

Iv Identify problems associated with shortages or surpluses of the

element(s) and/or compounds in the environment

Presentation of quantitative information

ii. Logical organisation of information with sections of the essay

iii. Ability to interpret research with meaningful and realistic conclusions

General neatness (consistent font size, margins, and spacing between

paragraphs, etc)

ii. Structured progression from introduction to conclusion, whilst

answering the question.

iii. Use of content page, diagrams, appendices, where appropriate.

iv. Achieve, but do not exceed, the word count
