How to work with Required Practicals: Part 4 and Part 5

Rubiks cube

Our reaction time is the time it takes for us to respond to something happening. In this time, our senses notice something and send a signal back to the brain, the brain then comes up with an appropriate response and sends a signal down to our muscles to carry out an action. Que Jiyani from Fujian in China was 13 years old when he achieved a World Record for his quick reactions. After training for two years, he managed to juggle three Rubik’s cubes in the air, solving them at the same time!!!  He managed to achieve this  in 5 minutes 6.61 seconds. For GCSE Science  – you need to be able to explain how to investigate how different factors can affect reaction times. It is one of the required practicals you must revise for AQA Paper 2.

 

For help with this try our new guides “How to work with Required Practicals: Part 4 and Part 5”. Part 4 focuses on the Biology practicals needed for Combined Science and Biology Paper 2 (AQA). Included in Part 5 are all the additional practicals needed on both papers for AQA Biology.

Part 4 includes:

Reaction Times, Investigating Population Size

Part 5 includes:

Preventing Bacterial Growth, Plant Response, Decay

You will find a brief description of what you need to know about each practical, and key questions you may be asked. As always there are questions to try, and answers to check your understanding.
