Reaction time

The video and worksheet set out a measurement challenge for students that can be carried out either at home or in school. They use a ruler length drop to record the reaction time for different participants. The results are recorded on a downloadable sheet that allows conversion of drop distance to a reaction time. They are encouraged to take multiple readings and submit them to NPL website, via a link in the worksheet. This resource could be used to investigate what affects reaction times in terms of the age of the participant or the environment noise and light levels. The second worksheet allows an investigation into whether the dominant hand is faster or slower to react.
