Dedicated to one of my colleagues from my previous school who has a passion for biology (amongst other things). She also has a great sense of humour (posing with a skeleton was her idea).

Today’s Gratitude Item: Finally managing to download an emulator for the Graphing calculator that I use with my senior classes. This will let me clearly show everyone what keys to press to get answers quickly and painlessly. Lets just say I wish I’d had a graphing calculator back when I was at school – these things are very, very handy.
