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.

Free radical substitution dance.

Free radical substitution dance.

Reaction mechanisms are beautiful dances, with the dancing atoms throwing out two (heterolytic ) or one (homolytic) arms out to their partner. Thus, I added a little beat to this reaction mechanism.
Cut & Stick reaction mechanisms

Cut & Stick reaction mechanisms

Sixth formers love cut & stick exercises. They are valuable because they familiarise the student with the mechanism, they promote discussion when done in groups, and are different to taking notes and practical work.

A simple worksheet on IUPAC nomenclature. A set of simple rules, followed by nine questions (branched chain alkanes and alkenes) over two sides. With separate answers sheet. First of a series.

A very simple presentation listing major functional groups. Could be printed out and used as a display.
A titration calculation

A titration calculation

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.
Oxidising alcohols

A straightforward worksheet on the oxidation of alcohols with information on the front, questions, then answers. In black & white for ready photocopying.
Mineral acids

I have made a very simple information sheet about forming mineral acids, for display or handout. Very few students are aware of this bit of basic chemistry, so I think it is worthwhile.
Classification hierarchy drag&drop

Classification hierarchy drag&drop

A wacky classification interactive activity that might amuse some students. Double click on the .html file and it will open in your browser. Drag the components into the correct order. You could make it huge using browser zoom controls. I have added a funky soundtrack to spice it up a bit. 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.
