In the past I have used a physical water circuit to explain to groups concepts such as potential difference and current. I wanted my own diagram of this, so produced this. Someone, somewhere might find it of use.
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.
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 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.
