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. Please note: in order to provide a rich interactive experience, my 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 made a crazy interactive widget to illustrate the ionic forms of glycine. Just for fun really.

I have added the new definitions to the SI wheel of units. Possibly for display in your lab.

I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.
