Here is Stephanie Bell‘s booklet – A Beginner’s Guide to Uncertainty of Measurement. There’s a lot of useful information in here, so please do have a read during the holidays. If you see any issues in here that might affect what you are doing with your procedures or data handling, please let me know.
Here is the second uncertainty guide. It is a more recent document and covers Higher in addition to Advanced Higher. You’ll probably find page 11 onwards has the most relevant information for investigation work.
Here is the first of the uncertainty documents to help you with your investigations.
The final page will help you to quantify some of the calbration uncertainties in instruments. If you use these values, remember to reference Learning & Teaching Scotland as the original source of the booklet.
Here are your summary notes for the Nat4 unit on electricity and energy. Remember that the end of unit test will be on Monday 3rd November. Ask me next week if you have any questions.
There are revision materials for this unit on BBC Bitesize.
We’re going to the library for the next few periods. Download the instructions using the link below. Use your own LO3 data instead of the numbers I have provided.
By the end of this activity you will be able to;
- manipulate raw data using formulae in cells
- plot a graph of your results
- add error bars to your graph
- add a line of best fit
- calculate the gradient and y-axis intercept of your line
Here are the solutions to the electricity and energy questions.
Here are the exam-style questions to cover the electricity and energy unit. I have included a copy of the relationships (equation) sheet and some data tables that you may need to attempt all the questions. Apologies for the larger file size, it’s due to all the circuit diagrams.
