All chemistry students should have this somewhere in their folder. Plus a sheet with ten questions.

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

A straightforward worksheet on the oxidation of alcohols with information on the front, questions, then answers. In black & white for ready photocopying.

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. Please note: in order to provide a rich interactive experience, my drag & drop 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.

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

A simple worsearch with some biology terms from KS3

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

Because I wanted to

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 used colour to enhance this simple display. Might be of use to someone.

My gift to you (now list in chronological order)

I made a crazy interactive widget thingy to illustrate the limiting factor graphs for photosynthesis. Just for fun really. Project it onto the whiteboard perhaps. Make it huge using the browser zoom controls. I hope that it entertains you.

I made a couple of graphics for my own use. Thought I would share them.

I made a very simple wordsearch. Update: I know have added a labelling exercise to compliment this

Double click on pretty poly(mers).html, and the activity will open in you browser. Simply drag the structure of each monomer to the box next to the name of the polymer. Good AFL around the whiteboard. A paper version is also available. Suitable for GCSE and A level students.

I made a tiny worksheet on calculating % composition

a simple worksheet

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