I made a worksheet for this common experiment. It might be of use to someone.

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 set of 30 bingo cards with ks3 biology terms. Just a different take on the vocabulary.

because I could

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

Cut & stick away.

Preparing for a lesson with a student on waves, I was searching for diagrams to illustrate it. The internet is awash with suitable diagrams, but they all seem to be low-resolution bitmaps. Being a vector graphic fanatic, I made some high quality graphics of my own. I offer them in pdf, keynote and powerpoint formats. If you would like the editable svg files, get in touch with me via my web site

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

A very simple worksheet. ( I have now removed the duplicated lamp symbol).

A tiny sheet where the student fills in the name of the reaction and the required reagents in the boxes. Start of a series. Covers reactions in OCR B.

A simple worksheet.

may be of use to someone, somewhere. NB now I have fixed the table, hopefully.

For GCSE chemistry enjoyment

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.

I have made a little interactive cartoon thingy about this concept. Double click on “osmosis.html” and it will open in your browser. Use the browser zoom controls to make it huge. May be useful as plenary around the whiteboard, in an interlude, etc etc. It can be previewed on my web site. Please note: in order to provide a rich interactive experience, my 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.

I made a tiny presentation for teaching ester nomenclature. Students are challenged with a few structures and challenged to name them. The following slide gives the answer. Available in powerpoint and keynote.

As title

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.

A simple handout illustrating a simple calculation of percentage yield. May save you some time.
