Back to school tomorrow, again ...

After returning to school on Thursday last week, we were out of school for four days with extremely cold temperatures, snow and ice ... the polar vortex!  Global warming leads to changing weather patterns ... changing jet streams ... a wobbling polar vortex.  Next issue on the horizon, a predicted El Nino might make 2014 the warmest in centuries.

Last Thursday, we worked on our behavior lab using fruit flies (Drosophila).   Students tested fly preferences to different substances and fruits.  We will collate and analyze data tomorrow.   Also tomorrow, speciation / Chapter 24.
