 Unit 3 – Investigative and practical skills in AS physics (ISA)

This unit assesses students’ practical skills and is carried out from March onwards. The topics for assessment change each year however students are required to complete the following;

A practical investigation provided by the examination board. Students should construct a table of results and plot a graph of their data by the end of the allocated time.

A 1 hour paper will be given for students to carry out analysis. The paper is split in to two sections-
Section A – This consists of a number of questions relating to the student’s own data
Section B – This section will provide a further set of data related to the original experiment. A number of questions relating to the analysis and evaluation of the data then follow.

The 3 units for assessment are weighted in the following way;

Unit 1 PHYA1                                                       Particles, quantum phenomena & electricity
Written examination – (70 marks/120 UMS), 6 or 7 structured questions
1 ¼ hours
40% of the total AS marks
20% of the total A Level marks

Unit 2 PHYA2                                                                             Mechanics, materials & waves
Written examination – (70 marks/120 UMS), 6 or 7 structured questions
1 ¼ hours
40% of the total AS marks
20% of the total A Level marks

Unit 3 PHA3T                                                   Investigative and practical skills in AS physics
Centre marked route T – 50 marks
Practical skills assessment (9 marks)
Investigative skills assessment (41 marks)
20% of the total AS marks
10% of the total A Level marks

For each of the examinations, students are given an equation sheet to aid their workings. A copy of the AS equation sheet can be found below.
