The seventh graders have been learning about the five characteristics that differentiate a living thing from a non-living thing.  Living things need energy, produce waste, grow and develop, reproduce and respond to the environment.  We placed yeast in warm sugar water (with green food coloring for fun).  The yeast responded to their new environment, they started to grow, they used energy and they started to produce waste (carbon dioxide) which blew up the balloon!
