Brad Williamson and his microrespirometers

Our fearless AP Bio Listserv moderator and the organizer of this NABT Bio Blog, Brad Williamson, gave an interesting workshop this afternoon.  He showed us how to build microrespirometers for a cellular respiration lab out of 1-ml syringes, plastic capillary tubes, germinated seeds (he used cabbage seeds), 15% KOH solution, and some homemade manometer fluid (soapy water with red food coloring).  All 30 teachers in the room got them working perfectly!  Here’s a link to a more fulsome description of the lab on his Exploring Life author web site.  Nice job, Brad
