What is the aim?
Observe the effect of different factors on reaction time
What is step 1?
Hold ruler between person’s thumb and index finger, lined up with 0cm mark. Drop without warning, and record distance dropped before caught
What is step 2?
Calculate the reaction time using Newton’s equation of motion, so t=squroot 2s/a
where s = distance dropped in metres, and a = 9.8ms-²
What is step 3?
Carry out repeats, but be aware that the person will likely improve over time
What is step 4?
Introduce a variable such as: before and after a sugary drink (stimulant), or with/without distractions
