This is a differentiated resource aimed at teachers and tutors that are delivering the OCR A Level Physics course. This lesson covers Unit 2: Errors, Precision and Accuracy.
Throughout the resource, there are a number of examples and AfL points to makes sure that students are moving along with the new ideas, with answers provided for all questions. There are also additional practice questions provided to give students extra practice on these areas if required.
The learning objectives and the associated links to the OCR A Level Physics A (H156/H556) Specificaition covered through this resource are:
Describe what an error is, and how an error can be caused.
Describe what is meant by precision and accuracy, and how to improve it.
Explain how to combine different types of errors.
Link your understanding of errors to the application of error bars on a graph.
1.1.3(d)(ii)/1.1.4(b)*/2.2.1(d) [M1.5, M3.2-M3.5]
NB: These specification links are correct at the point of uploading (22/08/17) and will be monitored for updates.
*There are 3 sets of data for this task in the resource, only data set 3 will cover this learning objective.
The resources included are intended to be used in the following manner:
- L3 Errors, Precision and Accuracy.pptx (58 slides)
This is the teaching resource and designed to be used as the front of classroom resource. This includes answers for student marking opportunities. Make sure that you go through the resource to see how the animations fit in with each of the slides. This resource is intended to last over 2-4 hours of teaching.
- L3 Errors, Precision and Accuracy.pptx (39 slides)
This resource is designed to be printed and provided to students as a students handout. All answers have been removed, and key pieces of informtion remain as to be a revision support. This does not have to be used.
All resources are ready to use to teach, but can be adapted to fit other exam boards, specifications and order of teaching.
