Units, Prefixes, Scientific Notation and Uncertainties

Here is a link to a presentation that I gave for the IoP on AH Uncertainties.

The slides are 1GB, so you might want to ask me to share those some other way. Here is a pdf of the slides, including example SQA Uncertainty questions

Below is attached various useful documents to assist you in this vital part of the course. It is when you begin to use this material when going through your own experiments that it will become clear. Take time to read and understand it.

AH uncertainties summary notes 2013 These are a great set of notes produced by SSERC.

Here is a pdf of the talk I did for Physics teachers on Uncertainties in AH Physics. If you want the powerpoint you’ll need to get in touch as it is 1GB!

Below is the presentation. It was made for teachers, but there are quite a few bits suitable for students. Maybe I should edit it for students. Let me know..

UPSN Uncerts These are the content statements covering this topic from the May 2016 Course Support Notes.

Use this document very sparingly, it is not compatible with some of the AH mark scheme, especially in that it recommends you always round UP in an uncertainty. This is NOT what you should do at AH.- You’ve been warned! Contact me if you have concerns.

Hope these help you through your course. I suggest you read them through several times and quite carefully.

Here is a link to a presentation I gave for the IoP on AH Uncertainties. It is worth AH students checking it out.
