ScienceMan’s Experience with… Juicing?

January 26, 2014 ScienceMan Comments 1 comment

January 3, 2014 ScienceMan Comments 0 Comment

Over Christmas, I had the pleasure of lounging around in a house that is loaded with plants… including blooming ones. Usually I just keep my mouth shut and leave anything associated with plant material to the very capable care of my wife. But I couldn’t resist asking about the hyacinths she had made bloom during the holiday season. I thought that the growing bulbs might be of use to science teachers who want a novel way of studying root systems,…
