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 came across an exam question which asked the student to identify an ester from two apparently very similar structures and a proton NMR spectrum. This is my attempt to explain the spectra pictorially. I will bundle it with my other ‘NMR examples explained’ series. (NB, I used spectra from a database. The original question shows an expansion of the multiplet peak due to methyl groups as a heptet, ie seven peaks, due to six protons, although this appears to be simulated. The methyl groups appear to be chemically equivalent to me so the multiplet should be a quartet, due to three protons, but I cannot tell from the database spectra. I have stuck with the exam board interpretation and mark scheme. The question is OCR A F324 Wednesday 27 January 2010 question 4)

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.

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.

A worksheet asking questions about the chemistry of unknown substances, as the exam boards do.

I improved my 'learn the functional groups " video by giving time for students to recognise & shout out the name before the name appears.

A learn-by-not-working activity suitable for the end of the summer term. Comes complete with the solution. 65 words from the three sciences. Word list on separate page.

For GCSE chemistry enjoyment

I made a clunky little video about this.

I made a little video of polymerising ethene. It probably will be of no use at all.

This is quite a challenging wordsearch, although it appears simple. ( I have now included a pdf of 30 atomic structure bingo cards)

Quick and rough. 7 slides to summarize ways of representing molecules using glycine as an example. Might save you some time.

I made a crazy interactive slide show widget thingy on this topic. 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 .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 this for my own amusement. I have now included my KS4 worksheet activity as a free gift.

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.

I have made a little interactive cartoon thingy to reinforce or introduce the two types of bond fission, heterolysis and homolysis. Just click on the bond fission html file and it opens in your browser. You can make it huge using the browser zoom controls. 19.9.19- apologies the file previously uploaded was done in error.

I made a fun video on this topic.

Just practice at recognising types of chemical species.

I made a simple summary sheet as a revision resource. It aims briefly to summarise the benzene evidence.

Just for fun
