I use this activity with modules 3 and 4 of the Myers Intro to Psychology.
It is a reaction time activity in which we explore psychophysics...we talk about Wundt and his preliminary work in Psychology then we go and do some ourselves.
Included are 2 activities and a data sheet. I use the detailed one with my AP Psychology students. You can use the data sheet to extend the activity if you wish.

You are bound to have something cool to share, sell it on Teachers Pay Teachers!
