Open the html file et voila. Drag the descriptions to the correct places and get a prize. Please note: in order to provide a rich interactive experience, my drag & drop 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.

2,2,4-trimethylpentane, or iso-octane used to feature heavily in the OCR Salters A level chemistry, because it is an important additive to petrol. It has slipped out of the specification, but the examiner must be sitting on many questions that might be recycled to test understanding. This is a simple information sheet that gives answers to a legacy question that one of my students was completing. It aims to answer difficulties with the question in a graphic way. The sheet runs to three pages and examines isomerism.

Sixth formers love cut & stick. They reinforce understanding and promote discussion. Cut sheet and stick sheet, with spaces to write in bond angles, number of bonding pairs and number of lone pairs.

I made a simple display of the atomic structure of various isotopes, with the emphasis on simplicity and clarity. Just because I wanted to. I also included it as keynote and powerpoint presentations.
