Unit 7 contemporary issues in science

Hi i am doing this unit and i am struggling with this unit as english isnt my strong point i would greatly appreciate if anyone could help me on how to write an example answer for question 2,3 and 4. These are the questions which i least understand. Thank you
Hi,There are a lot of supportive materials to be found on tes.com. If you type on TES Edexcel BTEC Unit 7 it will direct you to a range of step by step guides for the questions you are struggling with. I believe this year is about plastics and you will also find articles here on that which are also worth reading whilst prepping.

What about 2022
How would you get the answers for the 2022 paper? No one even knows the questions yet.

for question 2-Identify the different organisations/individuals mentioned in the articles
and suggest how they may have an influence on the scientific issue

what the organisation do
funding
research development
education
lobbying
regulations.

demonstrate comprehensive knowledge and understanding of how key organisations/individuals can influence the scientific issue by identifying and selecting different types of organisations or individuals.(including references/acknowledgements in footnotes from all 3 articles)
Influence-
Level of influence
Audience influenced


-Commons Select Committee on Energy and Climate Change influence research/ funding/politics/
-UK's Carbon Capture and Storage Association: research/ funding/ development/education
-Greenpeace: lobbying/ funding/ education
-Britain's official Committee on Climate Change: policy expert/ Britain's official Committee on Climate Change
-the International Energy Agency : research/ funding/ development/ education

CCS can reduce carbon dioxide levels
reducing levels in atmosphere, land management and bio energy with CCS is easy
energy consumption can be lowered
recyclability of CCS can be achieved
research is needed into carbon storage and use
research is needed into geological storage
research will allow for development of the innovative chemistry to convert CO2
into synthetic fuels and chemicals.


q1
Issues:
climate control
global warming
climate deal
Britain not yet launched carbon capture
CC is still in infancy
manufacturing or power industry as problems
local regeneration
Ethical implications:
used by high emitting countries/puts low emitting countries at risk
First world/Third world argument
risk to ecosystems
political decision
Social implications:
jobs in areas where fossil fuels brought in jobs
5
variety of jobs created
increased prosperity
decreased air pollution
revival of communities

Economic implications:
profit for Britain
carbon penalties
storage is valuable
extend life of north sea fields
committing to fossil fuels/lack of commitment to renewable energy
need to borrow money to start carbon capture
cost of starting carbon capture
cost of power
cost of transport
not meeting targets
viable alternatives e.g. wind/solar
Environmental implications:
lowers carbon emissions
keeps use of fossil fuels going
committing to fossil fuels/lack of commitment to renewable energy
decreased air pollution
deals with carbon dioxide produced in factories
can cause seismic activity
lowers global temperature
effects on weather
untested technology/risks


q3
Discuss whether article 3 has made valid judgements

how the article has interpreted and analysed scientific info to support the conclusions or judgements being made.
-vadility and reliability of the data
-refrence to other sources of info
Conclusions
CCS can reduce carbon dioxide levels
reducing levels in atmosphere, land management and bio energy with CCS is easy
energy consumption can be lowered
recyclability of CCS can be achieved
research is needed into carbon storage and use
research is needed into geological storage
research will allow for development of the innovative chemistry to convert CO2
into synthetic fuels and chemicals.
Validity and reliability:
range of sources
sources in agreement
more advantages than disadvantages- is it balanced
three authors still publishing/ stand scrutiny
data used
original data
opinions backed with data and references
some bias but both arguments given
References:
referenced throughout
professional bodies
some references very old e.g. Bottoms 1930
nothing past 2014
all references from same journal
sometimes quoting their own research
may be more current research that disagrees


q4-Suggest potential areas for further development and/or research of the scientific issue, from the three articles

description of further areas of development or research of the scientific issue given
consistently provide evidence from analysis/ evaluation of the articles throughout the skills of synthesising and intergrating relevant knowledge

Further development:
parasitic energy consumption should be lowered
develop alternatives for geological storage such as carbon mineralization
development of the innovative chemistry to convert CO2 into synthetic fuels and
chemicals.
development of technologies for monitoring, verification, and assessment (MVA)
to ensure that the CO2 remains trapped underground
CO2 conversion pathways
use of existing pipelines
value/use of carbon dioxide
Further research:
research in carbon storage and utilisation
determine the correct composition of carbonate minerals to be included in the
concrete matrix to reduce issues related to mechanical strength of the materials
how to upgrade carbon dioxide to a fuel
CO2 conversion pathways
increasing the efficiency of the absorption process on coal fired power plants
lowering costs
carbon dioxide leakage
risks and impacts of CCS
less production of carbon dioxide compared to increased removal of carbon
dioxide




question 5
Indicative content for question 5
Learners may cover a number of examples from the list below but would not be
expected to cover all to get full marks:
Tone and style shows awareness of audience:
varied audience
not all scientists
professionals
scientific terms- explained terms
Main Points
Feasible:
lower carbon dioxide
infrastructure available
providing jobs and regeneration
increased prosperity
increase profit
reduce carbon footprint
11
reduce greenhouse effect
reduce global warming
Britain meeting carbon dioxide target
removal of carbon dioxide from manufacturing
Not Feasible:
environmental issues e.g. seismic activity
no impact on carbon footprint
no impact on greenhouse effect
no impact on global warming
diversion of funding from renewable energy sources to CCS
increasing use of fossil fuels
cost of CCS
technology in infancy/more research needed/more development needed
risks
Conclusion
carbon capture is feasible/not feasible
use of supporting/conflicting statements from the three articles

Identify two organisations and two scientists mentioned in the articles and suggest how they have had an influence on the main scientific issues (6marks)
Identify key people / organisations and how they would influence the issue discussed. These people/ organisations can be the authors of the articles or mentioned within the article.
To score highly ensure you make links between the individuals and organisations and the articles. Responses must be able to explain how the identified party would be able to influence the issue, who they may influence and to what extent.
It is not necessary for you to produce an exhaustive list of all the organisations or individuals referenced in the articles but it would be advisable to provide an example from each of the categories listed in the essential content for Unit 7: Government and global organisations; Non-government organisations, professional bodies and associations; Universities and research groups; Private and multinational organisations; Voluntary pressure groups

Question 3
Discuss whether article 3 has made valid judgements. In your answer you should consider:
how the article has interpreted and analysed the scientific information to support the conclusions/judgments being made
the validity and reliability of data
references to other sources of information. (12marks)
Prepare notes answering these questions
Define what validity and reliability are
Do you think the article is valid?
Is there any bias?
Is it optimistic?

Information can be deemed reliable if
The study is repeatable and provides similar or the same results
Results are repeated by others
The pattern in the data can be identified in tables or graphs
Secondary data supports the primary data

Information can be deemed valid if
The investigation actually measures what it set out to measure
Provides some corroboration of other similar studies
Outcomes provides information which may improve the area of study
Panel of individuals review the investigation



Use and misuse of Data
Make sure all figures or information presented can be verified by others or by trusted scientific principles and publications
Read all points. Are the data calculations suitable for example?
Does the way the data has been collected fit in with usual methods? Could it have been done better?
Check the figures, look for outliers or missing numbers. These may indicate something went wrong

References used
Is the paper referenced throughout?
How old are the references? If dated are they still valid?
Check to see if still be cited to confirm if still valid
Are they from the same people or are they different?
If more people are referenced and they corroborate then this makes it more valid

Question 4 (35mins or 45mins extended)
Suggest potential areas for further development and/or research of the scientific issue from the three articles. (5 marks)
For this question when you read the 3 articles in Part A you should research potential new areas for development.
The command verb is ‘suggest’ which requires the learner picks out aspects of research in the issue and comment upon how they could be further developed or investigated















Question 5 (15marks)
This question is the only one that changes every year and hence why it is necessary you practise writing out different responses to the different type of audiences. An example of the question is
You are an infection control nurse. You have been asked to raise awareness among district nurses of the problem with antibiotic-resistant microbes that cause skin (topical) infections such as leg ulcers.
One of the roles of a district nurse is to visit the homes of elderly patients to change their medical dressings for skin infections such as leg ulcers
Your task is to write an article for district nurses about the possible benefits and limitations of using medical grade honey dressings to treat skin infections.
Use information from the three articles provided for this task. When writing your article you should consider
who is likely to read the article
what you would like the reader to learn from the article.

This question is worth the most amount of marks, but is the one you can’t prepare notes for as much.
Ensure you are clear you fully understand the contemporary issue and how each article relates to it
If you know certain phrases or key words you have trouble with remembering or spelling then you could list them here.

Certain phrases are used for certain audiences to get buy in for your written piece eg. CORPORATE CONTROL’ , ‘AGGRESSIVE PURSUIT OF PROFIT’,‘BETTER ALTERNATIVES EXIST’, ‘PROFOUNDLY DAMAGING’ , DESTROYING BIODIVERSITY’ and you could identify ot list some here too

If you are having to write a tabloid piece or a piece for the general public you will have to change some of the scientific terminology to phrases the lay person would understand and these you could also list here to save time in the exam

Finally if there are any key quotes which you think would benefit all the types of audience then write them under the section. Don’t forget to include the name of the person who gave the quote, it will save time in the written exam looking for the relevant quotes
