National Grid & Transformers GCSE Physics and/or Combined Science Differentiated Equation Worksheet

There are 14 differentiated questions around using the topics linked to the National Grid. The harder questions allow students to demonstrate their knowledge of rearranging the power equation for the primary and secondary coils of a transformer.

Student feedback says that they love the layout. They can measure their own progress and it is easy and quick to mark and leave specific feedback (the answers include a full method - this worksheet has 9 additional pages of notes). It has been designed to build confidence as well as low-stakes competition into lessons. Like students do in maths, students will be able to apply equations and use the triangle method for rearranging.

The font used is “OpenDyslexic” - this helps students with dyslexic tendencies to access the work easier. More information can be found on their open dyslexic website. This is saved as a pdf to keep the font working (if you have not got it installed). The word version is also included so that you can choose your own font and edit the document.

Typical layout of questions where Q1 is simplest and the last is hardest (towards AS Level Physics).

Typical example:
Q1 to 5 - 1 Chilli (Low demand). Focussed around remembering equations (students should use mini whiteboards or scrap paper for repetition)
Q6 to 8 - 2 Chilli’s (Low/Middle Demand). Focused around using the equation - e.g. simple conversion or having to rearrange the equation.
Q9 to 11 - 3 Chilli’s (Middle/High Demand). Rearranging the equation and using conversions.
Q12 to 14 - 4 Chilli’s (High Demand). Stretch questions, e.g. towards Year 12 or short written answers.

Designed so that students can choose where to start, although the highest ability will want to complete all of the questions.
Questions answered from the 1st column give you 1 chilli each. Column 2, each question is worth 2 chillis etc. At the end, count the chilli’s that the student has and this suggests a current working at grade.

Perfect for:
• Assessing prior knowledge
• Homework (easy to mark and suggest how to move forward as focused around skills of using equations).
• Starters / plenaries - part of “low stake” tests - build up a series of “mini-marks” on a tracker sheet before larger tests so students can identify their strengths and weaknesses.
• Recall and Retrieval
• Metacognition
• Self-monitoring
• Revision
• Cover lessons (fully explained mark scheme that can support students and non-specialist teachers)
