The symbol in the middle of the disc reminds me of the symbol for pure wool. In retrospect I don't like the image at all, its horrible - much like my week has been. I'm feeling increasingly frustrated with the uncertainty surrounding my work situation :(

Today's Gratitude Item: The Microbe Magic website. It has everything I need for the upcoming unit on Microbes and it means that I don't need to do too much to prepare. This site has activities, practical experiments and loads of information. All I'll do is write down some instructions for my students and decide which activities we will do as a group. Having it all there for one is so much easier than re-inventing the wheel.
