I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.

there are many diagrams of the fractionating column out there. I unashamedly drew on many of them as inspiration for this. However, they are almost exclusively low resolution, bitmapped graphics. I have made my version as an infinitely scalable vector graphic. I then used it to make this labelling exercise. Just for the love of it really. I hope someone might find it useful.

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

I recently downloaded the RSC’s very useful “education in chemistry” resource on titrations. The documents are beautifully produced, but I was appalled that the “diagram” column in the equipment tables were low resolution bitmapped graphics. I thought I would produce my own simple diagrams in vector form, so that they can be used at any scale without pixellation. I provide this as a pdf which you can copy and paste from freely, but if you need SVG files , please feel free to contact me via my web site. They may be of use to someone, somewhere.
Free radical substitution drag & drop

An alternative to my cut and stick exercise. Double click on the .html file, and it will open in your browser. You can zoom it so it’s huge using the browser zoom controls. Drag the structures to the correct places, then get a reward. 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 frome this hierarchy, the resource will not work.

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.

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

Reaction mechanism revision.

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. April 2025: added aromatic mechanism

Density worksheet

I made a simple worksheet about density. 5 pages. Two of info, one table of values, a page of questions and my answers. I have now added a keynote and powerpoint version.
