This is the second set of tips for avoiding some of the mistakes made by students sitting AQA GCSE Trilogy science papers. It is based on the exam board's advice, which can be downloaded from https://filestore.aqa.org.uk/resources/science/AQA-GCSE-SCI-TG-MISUNDERSTANDINGS.PDF, together with observations and explanations of my own. To read the first part of this summary, see https://physbang.com/2023/05/01/common-mistakes-part-1/. 7. … Continue reading Common Mistakes (part 2)
Specific Heat Capacity and Energy Stores
Two ways are suggested in GCSE Physics for measuring the specific heat capacity of a material. I have already explained the electrical method (see here) but it looks likely, from the advanced information supplied by AQA, that the other method will feature in this summer's Trilogy physics examination. So here's what you need to know … Continue reading Specific Heat Capacity and Energy Stores
Experimental data
One of the most important skills that is required for success in physics is the ability to handle experimental data in an appropriate way. This includes everything from correct use of units and equations to identifying anomalies, finding averages and recording calculations with the proper number of significant figures. All of these skills are tested … Continue reading Experimental data
SP1 – Specification
Topic 1 isn't really a topic in itself so much as the foundations that will be assumed to be in place for every topic that follows. It covers the key skills you need to know regarding units of measurement and prefixes that are used to increase or decrease the size of a unit. It also … Continue reading SP1 – Specification
