For those year six induction days or the like, this is a drag & drop exercise to label the bunsen burner. Double click on the html file and there it is!
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.
Dig the funky accent.

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"
A simple cartoon with half equations. Electrode labels now correct! I have now added positive charges to the hydrogen atom cores/hydrogen ions. The you tube version adds a funky beat.
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…
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 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)
This is a simple powerpoint giving names and formulae of ions. Knowledge of these can provide a key to understanding chemistry at GCSE and A level. Print these off, laminate them, and display in a prominent position in a lab.
(NB I have corrected the ammonium ion error)
