Students took part in the Tomatophere experiment where they attempted to grow two different types of tomato seeds, ones that had been on board the International Space Station  (Group H) and ones that were grown on from earth (Group G).  They submitted their results to the Canadian Space Agency.  Their contribution helped the CSA in the field of space farming, a critical ingredient in the design of a life support system needed to send humans to other planets.  Here is a link to the national results:  http://tomatosphere.letstalkscience.ca/ViewResults
