  1. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • An ISA is the Controlled Assessment Unit for Science. • It is worth 25% of your GCSE. • There is no tier of assessment so grades range from U - A*. • You only need to complete one ISA per GCSE but there are three available ISA’s for each GCSE. • Each ISA is made up of 4 parts • Research • Section 1 exam • Practical • Section 2 exam • ISA’s are done in lesson time and take approximately 7 lessons. • Your best ISA grade will be the mark sent to the exam board.

  8. Introduce the context of the investigation • 1 Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA Context: • Your teacher will describe the context in which the investigation is set. Relating the investigation to the context • Your teacher will describe the context in which the investigation is set. • You must research this context and write down how the results of your investigation might be useful, e.g. health and safety developments, energy efficiency, in industry, etc. You may be asked a question similar to this in the section 2 exam: • How could the results from your investigation be useful in the context that you have researched? • You may use information from your Candidate Research Notes to help you to answer this question. 3 marks

  10. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Planning and preparation • 2 Research: • Once you have been given the context of the investigation you will need to research: • one or two possible methods of carrying out the investigation • the context that has been set • any health and safety issues with the method(s) • These research notes must be written on the Candidate Research notes sheet provided by AQA • Your research should take no more than 3 hours, including homework. In an Additional Science ISA or Separate Science ISA you will also need to use some of this time to come up with a hypothesis. • Your teacher will check your notes before you take the Section 1 exam to ensure you have not included an prohibited information. Remember these are only supposed to be brief notes but they should include information on the factors such as the range, interval and number of repeat readings that you should take, and the variables that need to be controlled.

  11. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Planning and preparation • 2 Hypothesis: For a Science A ISA you will be given the hypothesis For an Additional Science ISA you will need to come up with a hypothesis Research sources List all of the sources you used to carry out your research, such as books, websites or CD-ROMs. Which source was the most useful and why? Method(s) Briefly outline a possible method that could be used to collect useful data to investigate the hypothesis. Think about what you will change, what you will control and what you will measure. Equipment List all the equipment you would need for your method. Think about how you will set your investigation up and what you will need to measure. Select the most suitable equipment to do this. You may want to draw a diagram. Risk assessment issues Record any possible hazards in each method, and the risks they present. Explain how you will reduce these. E.g. acid is an irritant and can cause holes in clothes. To reduce this risk I will wear goggles, wipe up spills and wash my hands. Relating the investigation to the context Your teacher will describe the context in which the investigation is set. You must research this context and write down how the results of your investigation might be useful, e.g. health and safety developments, energy efficiency, in industry, etc.

  12. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Complete the planning sheet and write a blank table • 3 Producing a blank table: • You will be required to independently produce a blank table for your results. • This is done under exam conditions once the research notes have been completed and before you sit your Section 1 exam • The table should be able to accommodate everything that the you are going to measure and record during the investigation. • The table should include appropriate headings and units. You may need to include additional information (e.g. start temp, end temp and change in temp).

  13. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Complete the planning sheet and write a blank table • 3 All these tables scored full marks

  14. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • ISA section 1 exam – Science A • 4 Section 1 Exam: • Up to 45 minutes is allowed for this. • The test may be taken in the normal teaching room, provided that you can be accommodated in such a way as to prevent any copying or unauthorised collaboration. However the test will usually take place in the hall, dance studio or drama studio depending on their availability. • If you normally have a reader, extra time, scribe etc. for exams then you will have the same arrangements made for the ISA exam. • Section 1 of the ISA will contain questions about the methods that you have researched and is worth 20 marks of the overall 50 allocated to the Controlled Assessment. • You may use your Candidate Research notes sheet, which you filled in during your research. Section 1 Exam: There are normally 5 questions: • Name two sources you used and analyse their usefulness 3 marks • Name a control variable and outline a preliminary investigation to find a suitable value for this variable 3 marks • Describe your plan 9 marks • This question could be on a variety of different topics relating to the idea “what makes a good investigation” - some examples are given in this guide 3 marks • Submit the blank table you have drawn for your results 2 marks

  15. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • ISA section 1 exam – Science A • 4 Research sources: • List all of the sources you used to carry out your research, such as books, websites or CD-ROMs. • Which source was the most useful and why? You may be asked a question similar to this in the section 1 exam: • Think about the research that you did to find out how to test this hypothesis. • Identify two sources that you used for your research. • Which of these sources was the more useful? • Why was this source better than the other source? 3 marks Additional marking guidance: • A clearly identified source is referred to by title and author or for websites at least the name of the website should be quoted • A clear comment on only one of the sources ay be sufficient to gain 2 marks if the answer implies a comment on the other source. • If candidates have taken part in peer discussion as part of their research, simply stating this is not sufficient to qualify for quoting a source. Similarly reference to their own notes or exercise book alone is insufficient.

  44. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Practical • 5 Carrying out the practical: • You can use the method and results table you came up with in Section 1 but it is likely that you will be provided with a method to follow and results table to fill in so class results can be collected. • There is no specified time limit for the practical work, although it is anticipated that most experiments should be capable of being completed within a one hour lesson. • If necessary however, the experiment may be continued over a number of lessons. Any paperwork, e.g. result tables, will be collected in at the end of the first lesson, and returned to the you at the start of the next lesson. • All results will be pooled together in the second lesson so everyone has a class set of results. • Categoric data: • Categoric values have values that are labels. E.g. names of plants or types of material. • You would normally use a bar chart to represent this data. • Continuous data: • Continuous values can have values (called a quantity) that can be given a magnitude either by counting (as in the case of number of shrimp) or by the measurement (e.g. light intensity, flow rate etc.) • You would normally use a line graph to represent this data.

  45. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • Complete practical and draw a graph of your results • 6 Producing a graph or bar chart: • You will be required to draw a graph or bar chart of your results • Title: • This should describe what your graph shows • Line of best fit: • This goes roughly through the middle of all the scatter points on a graph. The closer the points are to the line of best fit the stronger we can say the correlation is. • It can be a curve. Dependent variable (units) • Anomalous results: • Put a ring round any outliers to show you know they do not if the pattern. • Jagged line: • These indicate a broken scale. A broken scale is used when values close to 0 are not required. Independent variable (units)

However the test will usually take place in the hall, dance studio or drama studio depending on their availability. • If you normally have a reader, extra time, scribe etc. for exams then you will have the same arrangements made for the ISA exam. • Section 1 of the ISA will contain questions concerning conclusions and evaluationand is worth 30 marks of the overall 50 allocated to the Controlled Assessment. • You may use your Candidate Research notes sheet, which you filled in during your research. • You will also be given a data sheet with 4 case studies. Section 2 Exam: There are normally 4 questions, some of these questions are made up of more than one part: • Analyse and evaluate your results • What were the variables in the investigation you did? • - e) These questions are on a variety of topics and may vary in number from ISA to ISA • Analyse and evaluate the data given in the case studies • Sketch graph • Explain whether or not the results on the Secondary data sheet support the given hypothesis • Analysis of Case Study 4 This is only a guide there may be more questions based on the case studies • How could the results from your investigation be useful in the context that you have researched? 3 marks • Submit the graph or bar chart you have drawn of your results 4 marks

  48. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • ISA section 2 exam – Science A • 7 Variables: • These are physical, chemical or biological quantities or characteristics • State, give, name, write down: • Only a short answer is required, not an explanation or a description. Often it can be answered with a single word, phrase or sentence. • If the question asks the you to state, give, or write down one (or two etc) examples, they should write down only the specified number of answers, or they may lose marks for any wrong examples given. You may be asked a question similar to this in the section 2 exam: • What were the variables in the investigation that you did? • The independent variable was • The dependent variable was • One control variable was 3 marks

  50. Controlled Assessment Unit - CAUInvestigative Skills Assessment - ISA • ISA section 2 exam – Science A • 7 Resolution: • This is the smallest change in quantity being measured (input) of a measuring instrument that gives a perceptible change in the reading. Explain: • You should make something clear, or state the reasons for something happening. • The points in the answer must be linked coherently and logically. • The answer should not be a simple list of reasons. You may be asked a question similar to this in the section 2 exam: • Think about the way in which you took your measurements. • Resolution means the smallest scale division on the measuring instrument that you were using. • What was the resolution of your measurement for… • Do you think that this resolution was appropriate for this investigation? • Explain your answer 3 marks
