Content	Key opportunities for skills development
$Reaction times vary from person to person. Typical values range from 0.2 s to 0.9 s. A driver’s reaction time can be affected by tiredness, drugs and alcohol. Distractions may also affect a driver’s ability to react. Students should be able to: explain methods used to measure human reaction times and recall typical results$
$interpret and evaluate measurements from simple methods to measure the different reaction times of students$	$WS 3.5, 3.7$
$evaluate the effect of various factors on thinking distance based on given data.$	$WS 1.5, 2.2 MS 1a, c AT 1 Measure the effect of distractions on reaction time.$
