This is an awesome activity to help students see acceleration as it occurs. It is set out to use basic principles, the scientific method, to develop an understanding of acceleration.
Very simple setup, only a few materials needed. Questions included guide the students from the simplest form of acceleration through curved motions and centripetal accelerations. It can be extended to help talk about Newton's second law as well.
The best part...no math!
So if you're looking to improve the students writing skills in the sciences, this one is for you!
Includes a "for the teacher" section to help guide students in just the right direction.
