Hugely versitile, simple, engaging practical to find students’ reaction times using just a 1m ruler!
Designed for KS3 and KS4 but also adaptable for KS2 and KS5, this experiment is ideal to spice up Thinking Distances in GCSE physics/science. Students will appreciate just how long human reaction times can be, and see how far their ruler falls while reacting under certain conditions.
It could also be used to teach experimental ideas such as random error, accuracy & handling anomalies, being unbiased etc.
For KS2 & 3 detail can be removed for simplicity. For KS5 this is a great opportunity to explore error types, uncertainties and uncertainty propagation by finding range/2 and absolute/percentage error on t. If there is interest I can produce a KS5 resource for this experiment with OCR-A style questions.
It should take around 10-20 minutes depending on the group and how you use the questions
