Why should teachers do more than 12 practicals?
There is a minimum requirement of 12 core practical activities to be offered to students, however:
• some techniques need more practise
• you can provide increased opportunities for students to develop a mastery against the five CPAC areas
• some students may be absent when you deliver the practical
• practical work works to underpin teaching and learning, helping students to fully grasp the harder theoretical concepts
• practical work should be embraced fully and students should not be limited to practical skill development – it is simply too important.

Biology

Required practical example
Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction
ATa Use appropriate apparatus to record a range quantitative measurements (to include mass, time, volume, temperature, length and pH)
ATb Use appropriate instrumentation to record quantitative measurements, such as a colorimeter or potometer
ATc Use a laboratory glassware apparatus for a variety of experimental techniques to include serial dilutions

Chemistry

Required practical example
Measuring the EMF of an electrochemical cell
AT j Set up electrochemical cells and measuring voltages
AT k Safely and carefully handle solids and liquids, including corrosive, irritant, flammable and toxic substances

Physics

Copyright © AQA and its licensors. All rights reserved.
Required practical example
Investigation into the variation of the frequency of stationary waves on a string with length, tension and mass per unit length of the string
ATa use appropriate analogue apparatus to record a range of measurements (toinclude length/distance, temperature, pressure, force, angles, volume) and tointerpolate between scale markings
ATb use appropriate digital instruments, including electrical multimeters, toobtain a range of measurements (to include time, current, voltage, resistance, mass)
ATc use methods to increase accuracy of measurements, such as timing overmultiple oscillations, or use of fiduciary marker, set square or plumb line

One of our practical advisers commented recently….
“The adviser training provided a lot of ‘food for thought/reflection’ with regard to how we manage the delivery of practical skills to young people as practising teachers.
It also was very useful to consider how what we do would be seen by colleagues coming in and observing us”.
