Teacher entry: Space Club students are conducting an experiment, through www.tomatosphere.org, for the Canadian Space Agency (CSA)! The challenge is to compare the germination of two groups of tomato seeds, one as a control group and the the other as a treated group (having been placed in a space-like chamber at -80C for 37 days), and report the results to the CSA. Meanwhile students practice making hypotheses, make observations, collect and anaylze data; the results of which will be used in the planning for future space exploration on Mars.
