I made a crazy interactive widget to illustrate the ionic forms of glycine. Just for fun really. 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 needed a clean, scalable (vector)graphic of fleming’s left hand rule that I could freely use in my resources, so resorted to drawing my own. I thought I would share it. If anyone would like to use the editable SVG version or postscript or EPS etc, contact me.

An introductory sheet of answers, followed by cut and stick exercise for this challenging mechanism. Cut and stick promotes familiarity with the mechanism, promotes discussion when done in groups, and is enjoyed immensely by sixth formers.

This is a very simple worksheet. Link the name of the polymer to its monomer. Then draw the repeating unit. A drag and drop version may follow. Watch this space.
