I am doing a science fair project which involves human reaction times. Can I
set Excel up to measure and record the time between two inputs (keystrokes,
mouse clicks, etc...). Does Excel have a "stopwatch" function?

hi
excel doesn't have a built in "stopwatch" but a number of people have wanted
such.
see this site.
http://www.mvps.org/dmcritchie/excel/datetime.htm
all about time and dates, how to calculate, measure, extract, ect.
this is a large site but down towards the bottom is a "timer". not sure if
you can use it but it might give you ideas.

As a scientist to be, I can sympathize with your plight. check out this sight:

Option Explicit
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub Test()

Dim lStartTime As Long

Randomize

Sleep (Int((10 * Rnd) + 1) * 1000)

lStartTime = timeGetTime()

MsgBox "Press the Enter key as fast as you can", , _
"reaction speed tester"

MsgBox "reactiom time: " & timeGetTime() - lStartTime & " milli-seconds",
, _
"reaction speed tester"

End Sub
