Flame in Freefall

Submitted by SteveMaier_ on Fri, 10/06/2017 - 21:40

A novel activity that demonstrates one of the effects of a microgravity environment. In this exercise, the structure of a flame is filmed while simultaneously plotting the acceleration of the system as it is released and experiences freefall. The apparatus is low-cost, possibly using only scrap materials found in the classroom. A PocketLab One is paired with a smartphone and used to collect the data.  Conceptually, the exercise is straightforward, though considering noise in the data, limits of the system, and chemistry applications could easily enrich the content. There are opportunities for engaging in engineering design process as well.
