I have tried to produce a clear example of an acid/base titration for use on the board or as a handout. I used colour to make it as clear as possible.

I made a series of templates for the main aliphatic reaction mechanisms in OCR chemistry A level. They resemble exam questions where students have to complete the reaction with partial charges, lone pairs and curly arrows. The intention is that they can be printed out by students as often as is required, for practice. A solution is provided for each example. Included are: nucleophilic substitution, electrophilic addition, nucleophilic addition, radical substitution and elimination.

I have tried to illustrate the concept of separation of water molecules rather than breaking covalent bonds when water is heated with a quick and dirty animation. Click on the water boiling.html file and it will run in your browser.

This runs in your browser…click on the correct answer and you get feedback. Eight slides. 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 quiz.html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the quiz.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.
