A simple summary sheet.

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. It should now work 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. stdobbs.com ©D&D production

Presented as pdf, powerpoint and keynote files. A single poster. May be useful to someone in form time or assembly etc.

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

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.

simple quick video, three chromosomes, maybe students can shout out the stages. (hope it’s accurate enough, if not students can point out the errors!)

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.”

My extremely tacky public information film.

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"

Just because I wanted to. (NB got rid of the aberrant apostrophe)

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.
