Students are give some material resources to keep a single marble "moving" before it finally drops into a beaker (plastic)
The challenge is to keep it moving the LONGEST.
With such simple resources and some stop watches the students spend as long as needed to design, test and finally submit an entry for the challenge.Over the years I have seen most students go for the SIMPLE DILUTED GRAVITY technique..lots of long ramps end to end..they do work well if lined up well and prove good physics ideas.
The best solution was wonderful....a set of cones (upsidedown Chines rice pickers hats) with a hole at the point..a marble is released in the top hat and spirals slowly into the middle, drops onto the edge of the next hat below and so on...yes still diluted gravity but elegantly more compact and easier to construct...of course the students will come up with ideas you have never dreamed of........
