I made a crazy interactive widget thingy to illustrate the limiting factor graphs for photosynthesis. Just for fun really. Project it onto the whiteboard perhaps. Make it huge using the browser zoom controls. I hope that it entertains you. Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

I have made a deliberately clunky representation of this, using gel-pen type colours. Just the sort of thing to amuse some sixth formers. Relish its unprofessionalness. I do. UPDATE: link added to movie on YouTube of hydrolysis reaction. Double click on the html file, and it will open in your browser.
