Investigating Reaction Times - GCSE Biology

🦊 In this GCSE Biology video, we explain reaction time as the duration required to respond to a stimulus, like the sound of a starting gun indicating runners to start. Reaction times can be measured through various methods, including computer tests and the ruler drop test, where the distance a ruler falls before being caught indicates the reaction time. Factors affecting reaction times, such as the time of day, caffeine intake, and alcohol consumption, are explored to understand their impact on the nervous system. In experiments, the independent variable is the factor intentionally changed, such as the time of day, amount of caffeine, or alcohol, to observe effects on reaction times. 👋 Hi, we’re Launchpad Learning.
