Guidance for your students
Internal assessment of coursework is 33% of your final grade.
Decide exactly what you want to investigate.
Think about any things (factors) which might affect your results, and how to control them.
Try out different ways of doing your experiments to decide which is best.
Consider how much data you need to collect, and plan repeat experiments to check for reliability.
Do some tests to check that you have chosen good ranges to test – report the results.
Work safely – have your plans checked before doing experiments.
Describe how successful you were at controlling outside factors.
Collect data over a good range and repeat to check reliability.
As you do the work, check how well repeat values agree.
Look at the results as you go along – they may show that you should change your plan, and test more or different values.
Work carefully, and accurately – if necessary have few practice goes to develop your skill.
Use tables, charts, graphs or calculations to show any patterns in your results.
Say what conclusions you can make from your data.
Explain your conclusions using your science knowledge and understanding.
Think whether any improvements in your apparatus or method could give more precise and accurate results.
Check how closely each result fits the general pattern and look for any outliers.
Suggest some improvements or extra data you could collect to be more confident in your conclusions.
Write a full report on your investigation.
Make sure your report is laid out clearly in a sensible order.
Describe the apparatus you used and what you did with it.
Remember to show all units correctly (e.g. cm3).
Take care with your spelling, grammar and punctuation, and use scientific terms where they are appropriate.
Your investigation should be based on the data you collect from your own experiments..
However, you may sometimes want to refer to ‘secondary data’ to support your conclusion or evaluation. Secondary data can come from:
- other students
- science books
- the internet.
Keep detailed notes of each stage of your planning and work. Check each result as you get it to see that it fits in with others you already have – if not, consider whether you need to repeat it to check.
