A2 Unit 3 Part B exam style questions Teachers’ notes

The Unit 3 exam will normally contain a single question in Section B that requires an answer in continuous prose. It is designed to provide synoptic assessment and allows candidates to select their own examples to illustrate How Science Works ideas.

These questions are being provided to help students practice this type of question.

Note, however, that these activities, while being in the style of a Unit 3 exam question, have not been subject to the careful evaluation and revision of questions undertaken by AQA during the preparation of operational exam papers. Note too that mark schemes are revised in the light of the responses from candidates. The general policy is to give credit for all correct answers even when they do not, initially, appear on the mark scheme.

Marking

1. Ethics

Science explanations may not be relevant in this question. A very wide range of issues would be suitable. These include: medicine testing in UK, in developing countries, or using animals; biofuels; enforcement versus advice in lowering health risks; regulation of reproductive technologies; individual rights in treatment of mentally ill patients; laws on recreational drugs; measures to reduce climate change, individual freedoms versus future generations; biodiversity issues and the different justifications that might be used.

Use standard 4 level mark scheme.

A level 4 answer would include the following:

  • explanation of ethical dilemma –awareness of two sides
  • explanation of framework used
  • framework appropriate for dilemma
  • clear argument using ethics
  • acknowledgement of counter argument

2. The media

Suitable topics for examples would include:

MMR

factors small changes to health risks

Climate change

genetic determinism, particularly single ‘gene for ...’

harm from illegal drugs

biodiversity

Use standard 4 level mark scheme.

A level 4 answer would include at least half of the following points, relating them to specific examples:

Good reporting should include

  • an indication of the extent to which findings are accepted by scientific community
  • an indication of the relevance to society and the policy options that might flow from it
  • some explanation of the science behind the story
  • distinction between absolute and relative risk
  • information on sample size, spread of results and significance
  • a celebration of important new discoveries

It should not

  • report a single study as definitive
  • use a single personal story as evidence (though it might be useful to attract attention)
  • give the impression that an individual with a contrary view is to be taken as seriously as the consensus
  • present controversy as failure rather than normal part of scientific process
  • confuse correlation and causation

3. Interdisciplinary research teams

Use standard 4 level mark scheme.

A level 4 answer would include at least four of the following points, relating them to examples from the topic chosen:

  • expensive equipment
  • collecting data from different locations
  • processing large amounts of data
  • complex systems are influenced by a range of factors that involve many different scientific specialisms
  • confirmation of results by different groups or using different methods
  • confirmation of effects in different environments
  • sharing expertise with different countries

4. An ethical code for scientists

Use standard 4 level mark scheme.

A level 4 answer would include about six of the following, relating them to relevant examples:

Rigour, honesty and integrity

  • conflict of interest can distort interpretation of results or influence advice given
  • perception of conflict of interest undermines credibility

Respect for law, life and public good

  • science research has many potential harms
  • recognition of ethical dimension
  • individual researcher must be responsible in new fields like nanotechnology
  • justification involves cost benefit
  • definition of public good very variable, (some would reject weapons research )

Responsibility for communication: listening and informing

  • important to share knowledge with the society, it may influence policy
  • results must be honest and not suppress unwanted data (such as side effects from drugs)
  • false results may lead to harmful policy or treatment

Unit 3 Part B exam style questions

These questions are similar to those in part B of the Unit 3 exam. They are synoptic questions. Synoptic assessment is defined in the specification as:

Synoptic assessment requires candidates to make and use connections between different areas of the subject form both AS and A2 to demonstrate scientific literacy, in particular by:

  • applying knowledge and understanding of ideas about How Science Works and science explanations to any relevant situation or context
  • using knowledge and understanding of principles and concepts about How Science Works in the analysis and evaluation of a range of issues in science and technology including novel contexts
  • bringing together evidence forma range of different contexts to develop a general argument about an aspect of How Science Works.

Quality of written communication will be taken into account in awarding marks for these questions. Remember that this includes your ability to develop a good argument, where claims are supported by evidence.

1. Ethics

Many policy decisions about the applications of science and technology involve more than deciding whether the application is safe and effective. It also important to consider ethical implications, these might be relevant for groups such as patients, animals or future generations.

There are several frameworks used to discuss ethics. Two important frameworks are: a consideration of consequences, and the use of intrinsic rights and wrongs.

Choose and describe any policy decision that would involve both science and ethics. Discuss the ethical dilemmas involved and explain the decision that you would favour using one or more ethical frameworks to justify your answer.

(12 marks)

2. The media

The popular media play an important role in providing information about science to the public and in encouraging public debate about policy issues. However science stories, like all others, have to attract readers.

Discuss the features of good and bad science journalism using examples from any topic or topics you have studied.

(12 marks)

3. Interdisciplinary research teams

“Much scientific work ... nowadays involves collaboration in large interdisciplinary teams, often from several countries.”

Explain the value of such teamwork in the context of climate change, biodiversity or any other similarly complex topic of your choice.

(12 marks)

4. An ethical code for scientists

Many scientists have recognised the need for a formal code to set out the ethical practices expected of scientists. One widely accepted code is that given below.

Rigour, Respect and Responsibility: A Universal Ethical Code for Scientists

Rigour, honesty and integrity

  • Act with skill and care in all scientific work. Maintain up to date skills and

assist their development in others

  • Take steps to prevent corrupt practices and professional misconduct.

Declare conflicts of interest.

  • Be alert to the ways in which research derives from and affects the work of

other people, and respect the rights and reputations of others.

Respect for life, the law and the public good

  • Ensure that your work is lawful and justified
  • Minimise and justify any adverse effect your work may have on people,

animals and the natural environment

Responsibility for communication: listening and informing

  • Seek to discuss the issues that science raises for society. Listen to the

aspirations and concerns of others

  • Do not knowingly mislead, or allow others to be misled, about scientific

matters. Present and review scientific evidence, theory or interpretation

honestly and accurately. Declare potential conflicts of interest.

Discuss the benefits of such a code. Referring specifically to the three principles in italics discuss the problems that arise if such principles are not applied in scientific work. Give examples from topics you have studied.

You may refer to the other principles or not as you wish.
