A simple simulation of the experiment. Unzip the file. Open the folder. Double click on ‘spring stretch version 4.html’ and it opens in your browser. Add the masses by clicking the buttons, and watch the spring stretch. Use a ruler to measure the extension. (The anomaly on the graph at 3N is probably due to a draught of warm air expanding the spring as a door was opened). Enjoy! A preview is availableon my web site. 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. ©D&D production

A simple cartoon with half equations. Electrode labels now correct! I have now added positive charges to the hydrogen atom cores/hydrogen ions. The you tube version adds a funky beat.

There is a beautiful graphic depicting this on the internet. However, it is a bitmapped graphic . I have adapted it as a a scalar graphic, with improvements. Please get in touch if you want an editable version.

A very simple worksheet to aid the distinction of addition polymers from condensation polymers. Explanation on page 1, questions on page 2.

A student was having difficulty remembering which bits of the heart were which, so I made this simple diagram.
