No frills short presentation illustrating the calculation of concentration in a step by step way.

A simple video illustrating the neutralisation of hydrochloric acid by sodium hydroxide, in terms of symbols.

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

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

A device to help students remember the first ten names of the alkanes, and hence have the key to IUPAC nomenclature

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

Just a very simple display.

Second in a series. This worksheet covers different functional groups. Information on the front, 6 questions on the back. In black and white for ease of photocopying. With answers.

A very simple presentation listing major functional groups. Could be printed out and used as a display.

I have added the new definitions to the SI wheel of units. Possibly for display in your lab.

A simple worksheet on IUPAC nomenclature. A set of simple rules, followed by nine questions (branched chain alkanes and alkenes) over two sides. With separate answers sheet. First of a series.

This is also available on my You Tube channel below.

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.

An introductory sheet of answers, followed by cut and stick exercise for this challenging mechanism. Cut and stick promotes familiarity with the mechanism, promotes discussion when done in groups, and is enjoyed immensely by sixth formers.

Reinforces understanding of this important mechanism. Sixth formers LOVE to cut & stick.

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

A cut and stick exercise to help reinforce this very important concept. Students cut out the pieces and arrange the pieces to give the correct mechanism. Prepares students for those five mark questions where they often lose marks. Other mechanisms to come plus drag and drop versions, so watch this space…
