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.

I made a tiny cartoon illustrating the two reaction profiles

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.

A very eccentric revision movie about making salts. Uses repetition to aid memory.

Info sheet followed by a bit of practice in the calculations.

Could be useful at the end of term. Students could then research some scientists of whom they hadn’t heard.

I have made a simple information sheet for this important, but much neglected, topic.

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called “Practicexamquest.”

I have made a little movie to simply distinguish between SN1 and SN2. It is similar my youtube video shown ( no music though- if you want that, just use the youtube!) I have not added commentary, leaving that to the teacher. If required, I could add it. Update: now sn1 improved so it is more simultaneous.

I made a tiny cartoon to contrast the action of a zinc electrode as an electrochemical cell or as in electrolysis. Double click on 'zinc electrode.html"

I set this to a funky beat, in an attempt to aid memory. Play it over and over again. If it’s too large to download, you could play it directly from this page, pressing the fill screen button. Why not play it at the end of many lessons, getting students to chant the names of the functional groups as they appear? A real process of learning.

I made a tiny, simple little interactive animation thingy to illustrate particles in a clunky kind of way. Just the three states of matter.

A simple cut & stick exercise

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)

I made a simple display of the atomic structure of various isotopes, with the emphasis on simplicity and clarity. Just because I wanted to. I also included it as keynote and powerpoint presentations.

I made a definitions sheet for reaction mechanisms for a student of mine. I thought I would share it.

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